    This is fantastic, thank you!

    I had set up Zotero to use as a portable app with LibreOffice and the firefox connector so that I had a working desktop for research and writing on a thumb drive.

    Then all was shot to hell with the new version of FF

    You have saved my bacon, thank you!

    I'll report issues if and when they happen, please keep up your fantastic work.

    thx

    Thanks a lot for this comment Smile I recognize myself in your words. My problem was similar and with quantum & zotero 5, everything was thrown away. I made this version for me, so why not share it and learn stuff when doing it?

    When update is available,

    When update is available, Zotero will ask user to reboot to apply update. If the user clicks 'yes', Zotero will show an error saying that profile cannot be loaded. And it will create folders in %appdata% and in %localappdata%.

    This is expected, as when re-starting, Zotero won't use the launcher... But, is there a workaround that I can use in the launcher.ini options? Blocking the update, or force the launcher to be used when re-starting?

    As you're providing updates yourself, I recommend blocking the update as described here: https://forums.zotero.org/discussion/36581/disable-check-for-updates

    Your opinion?

    Thanks. I modified those lines in App\Zotero\defaults\preferences\prefs.js as follows:
    user_pref("app.update.auto", false);
    user_pref("app.update.enabled", false);

    It's working, but can I have a feedback here? Is it the best way to do it? Wouldn't it better to add a user.js or modify the prefs.js in the profile rather than in the program itself? If yes, I don't really know how to do it as such file in DefaultData folder won't work...

    Working, but need fix for multiple profiles

    Thanks for this, seems to work fine.
    I'm working on an install with multiple profiles (start with -P flag).
    Only issue is that I needed to comment out the command line argument for datadir and turn back on the option to allow it to be user set in the profile.
    This seems to revert back to the behaviour of creating a folder in the Windows user directory (I saw your post in the Zotero forum re this).
    Not critical for me at this time, but figured I'd say thanks, and mention this minor issue (I doubt many people are running multiple profiles).

    Hi !

    Hi !

    Thanks for your feedback. I'm personally using two profiles for Zotero, and I'm not experiencing your issue, since I'm using two Portable Zoteros!
    That's the most convenient way I found (for me) not to leave traces on the computer running the program...
    The only problem is that it uses twice the 100+MB that the program needs Beee But I personally don't care.

    I think your can workaround something with a batch file modifying the ZoteroPortable.ini at each run... I did this for a while before Zotero 5.

    It Does

    Symbolic links require admin rights. As such, they can't be used for apps which don't themselves require admin rights due to their nature (system tools, etc).

    Sometimes, the impossible can become possible, if you're awesome!

    Yes, I have forgotten about that. One can only hope there is an argument option to specify profile directory like chromium in the future.

    Workaround

    Well, it is possible to specify a profile directory in Zotero with the -datadir flag. Actually, I'm using this flag in this portable version.
    If you go to App\AppInfo\Launcher\ZoteroPortable.ini you'll find : '-datadir "%PAL:DataDir%\profile"'

    You can change it to something else... Like a hard-coded path instead.

    BTW, Zotero 5 is based on Firefox, and as Firefox, you can install it without admin rights on a computer. If you don't use Zotero from an usb key or if you don't care about leftovers on the computer, you can actually use the official installation package. Zotero will install in AppData and your profile won't move each time you launch it.

    Sorry

    Hi,

    Sorry, I don't really know how to do that properly. But you definitely can install multiples instances of ZoteroPortable. It just have to be in different folders. For example, you can install to F:\PortableApps\Zotero and F:\PortableApps\Zotero 2nd Profile. You'll have to exit the first instance before launching the 2nd one.

    That's how I'm doing it currently.

    Thank you for creating this

    Thank you for creating this portable version. Its very useful to those of us who lack admin rights to install software. Using a portable version of Zotero allows me greatly improved productivity at work.
    Your dedication to open source software and Zotero is surely helping many thousands of people.

    false positive?

    I think it's a false positive due to the adding of a nsis file to handle better portabilization. But I'll try to figure it out.

    edit: yes, looks like false positive to me. Official Zotero package has the same report from virustotal. I'll ask them.

    sorry for late reply

    Hey,

    I have no issue with that. I don't think it's related to my package or to Zotero. It's probably a configuration issue. What browser do you use? Do you have the latest version of the Zotero connector installed?

    Just got your portable program from GitHub. Thanks for creating it. I've got an older laptop as my primary computer now (unfortunately), so I'm trying to keep most apps portable. This is a big help, thanks!

    I'm using Firefox Portable.

    I'm using Firefox Portable. When I right click an item in Zotero and select "View online" or "View PDF" or "View Snapshot", how can I force the webpage link/snapshot or PDF to be opened within Firefox Portable?

    I guess it maybe easier and more possible to implement this in Zotero Connector to achieve a two-way communication, i.e., not only can Zotero connector send a webpage/PDF from Firefox Portable to Zetero portable to save it, but also it can capture all viewing requests from Zotero portable and send them back to the Firefox portable where the Zotero Connector is installed. This can allow viewing all Zotero items right within the portable browser.

    I understand that this request may be somehow out of scope, but if forcing the webpage/PDF saved in Zotero to be opened within Firefox Portable, it will still be really great and convenient.

    Thanks!

    %APPDATA%\Microsoft\Word (empty)

    Any way to turn off the two websites opened on first launch? Or are they necessary? Anything else that might get in the way of release? The defiined Base Directory in Options - Advanced, does that need to be portablized in some way? Anything in the sqlite database we'll need to portablize (relevant custom code is in Firefox and other apps that do this)? If this uses Mozilla style extensions, does that need portablizing like Firefox's does?

    Hey!

    Thanks for the feedback John.
    I just addressed the two empty folders. I'll publish the fix.

    For the rest of your comments:
    - Two websites? Only https://www.zotero.org/start is opened on first launch for me. It's not per se necessary, but Zotero is a bit useless if you don't install the browser extension. I could stop this by creating a default profile. Do you want me to do it?
    - The base directory is handled by the ZoteroPortable.ini file, on line 3 : https://github.com/pedrom34/ZoteroPortable/blob/9a5864f0086e122e307e8d3c...
    - For the sqlite database, I am sorry, but I don't really understand. Can you please link me the custom code you're referring to?
    - It does use Mozilla extensions. For the portablizing part of thoses extensions, I do not know how to do it... Can you point me a link?

    Single Site, Extensions, SQLite

    Ah ok. Yeah, I see what you mean by a single site. The other was due to the VM I was running in.

    For basic SQLite with a PA.c Launcher, check out Isotoxin Portable. The custom.nsh within AppInfo\Launcher shows the basics.

    For Mozilla extensions, check out Firefox Portable's launcher. It's custom code but similar to the above. It's in Other\Source. Line 536 of FirefoxPortable.nsi.

    If you need some help with it, reply and let me know. I'll hopefully have time next week as the unwanted bathroom reno should end tomorrow and our cat's last weekly appt is Friday for oral chemo starting monthly. And I should have the platform update out tonight or tomorrow.

    SQLite

    I took a look at sqlite. I ran some tests, added some documents, references... None contained hardcoded path like Isotoxin does. Every resource I added has a relative path:
    https://i.imgur.com/JtW3FiP.png

    I'll take a look tomorrow on the plugins, but I don't know all of them... So I don't really know if it will need to be handled like in Firefox... (list of plugins: https://www.zotero.org/support/plugins)

    I'll let you know if I run into issues.

    I really hope your cat is going to be ok!

    Have a nice evening/day Smile

    Regarding your questions, I couldn't find any extensions using hardcoded storage that will need me to add the custom code.

    You shouldn't do that.

    You shouldn't do that, as the profile will stays on the hard coded path you specify. But, if you really know what you are doing:

    - Copy ZoteroPortable.ini from Other\Source, modify it like this: AdditionalParameters=CommandLineArguments=-profile C:\Users\SanPe\Desktop\Profile -datadir C:\Users\SanPe\Desktop\profile
    - Open ZoteroPortable\App\AppInfo\Launcher\ZoteroPortable.ini and remove the line reading CommandLineArguments='-profile "%PAL:DataDir%\Mozilla\Profile" -datadir "%PAL:DataDir%\profile"'

    Or more simply, do not copy the ZoteroPortable.ini from Other\Source, and modify the line as you wish in ZoteroPortable\App\AppInfo\Launcher\ZoteroPortable.ini

    If you want to use different Zotero profiles, you can just install 2 Zotero portable on two different folders.

    Thanks!

    Thanks a lot for your detailed reply, which is very helpful.

    Now I'm ready to load another datadir. But this could be tricky: the datadir I would like to load (by Zotero 6 portable) belongs to an older version of Zotero. In fact, that datadir was generated with Zotero 4 within Firefox portable U:\PortableApps\FirefoxPortableESR\Data\profile\zotero, and I have been using this datadir within Firefox portable for almost 10 years. Now I would like to switch to the newer version of Zotero 6 portable and hopefully get rid of the dependency on a very old version of Firefox portable, but without losing the ability to load the old datadir by Zotero 4 within the old Firefox portable. This is because, in this older version of Firefox portable, I have many browser sessions containing hundreds of tabs which are opening too many PDF attachments stored in this old datadir of Zotero 4 within Firefox portable (some of them are using zotero://xx/ as URL, while the others contains absolute paths such as U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\storage\ABCDEXYZ\filename.pdf). So I can't move the datadir U:\PortableApps\FirefoxPortableESR\Data\profile\zotero to other folder. Also, this datadir is too huge to make a full backup or move: it's almost 10GB containing ~300K files in ~4K folders.

    So what I want to achieve is to use Zotero 6 portable to load U:\PortableApps\FirefoxPortableESR\Data\profile\zotero as a datadir specified in \ZoteroPortable\App\AppInfo\Launcher\ZoteroPortable.ini (thanks again for your reply), and use it normally (editing & adding new Zotero items/entries). But occasionally, I still want to load the same datadir in Zotero 4 within the old Firefox portable (after closing Zotero 6 portable so that there is no conflict), at least in read-only manner, without editing any entry/item or adding anything new. After all, it would be extremely painful to migrate all browser sessions/tabs pointing to Zotero 4's PDF attachments to another browser, so I might have to keep the paths and file structure of this old datadir unchanged.

    From my understanding, once I load the old datadir by Zotero 6 portable, the SQL database U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\zotero.sqlite will be updated to a newer format/version. Then, when I load the same datadir and the updated zotero.sqlite database using Zotero 4 within the old Firefox portable, will there be any corruption in Zotero's database file zotero.sqlite? I can backup the old zotero.sqlite before loading it using Zotero 6 portable, but when editing and adding new entries, the zotero.sqlite will be updated to a newer version/format as I remember, so I wouldn't be able to load the updated zotero.sqlite (containing new entries added by Zotero 6 portable) using Zotero 4 within Firefox portable if the updated zotero.sqlite is incompatible or if this results in corruptions. So what could be the best practice/solution for my situation?

    Many thanks again!

    WOW.

    Wow... I'm sorry, but wow. This situation is really unbelievable.

    I don't think there's a good way out.
    Personally, I would switch to Zotero 6 and never go back to Zotero 4, no matter how long it takes to switch.

    But, two comments:
    - Zotero, like Firefox, is not really designed for such use. You are in a situation related to a side effect of your non-standard use,
    - I think this forum is not really the right place to ask that kind of question.

    Maybe try the official Zotero forums where there are more researchers and students who may have faced a similar situation.

    Thanks for your suggestion. I'll probably install another Zotero 6 portable and copy all the contents from U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\ to U:\PortableApps\ZoteroPortable_Copy_2\Data\profile\, and then upgrade that datadir (and the zotero.sqlite) using Zotero 6 portable (hopefully there won't be any issue, or should I first upgrade using Zotero 5 portable and then upgrade again using version 6?), while gradually and painfully changing all the old U:\PortableApps\FirefoxPortableESR\'s sessions/tabs' URLs from something like U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\storage\ABCDEXYZ\filename.pdf to U:\PortableApps\ZoteroPortable_Copy_2\Data\profile\storage\ABCDEXYZ\filename.pdf, and maybe also migrating these very old browser tabs to another browser or to Zotero 6 portable's PDF reader tabs.

    So now my question is, once you and John make Zotero portable official, when I update Zotero using PortableApps.com Platform's updater in future, will both U:\PortableApps\ZoteroPortable\ and U:\PortableApps\ZoteroPortable_Copy_2\ get updated (just like Firefox portable's "_Copy_2" or "_Copy_N")? And for now, before it goes official, after I manually download the .paf.exe from GitHub, and choose "Install a New App (paf.exe)" from the PortableApps.com Platform's "Apps" menu and locate the downloaded .paf.exe to update Zotero portable, will it update both the U:\PortableApps\ZoteroPortable\ and U:\PortableApps\ZoteroPortable_Copy_2\?

    Thanks again!

    Well, if you update ZoteroPortable, it won't update a copy of ZoteroPortable.
    I guess we could workaround a solution about a second profile just like Firefox2ndProfile does. But I really don't understand how to adapt this to Zotero...

    No problem. According to

    No problem. According to this and this, it seems that the installer is already able to update both U:\PortableApps\ZoteroPortable\ and U:\PortableApps\ZoteroPortable_Copy_2\.

    I also got confirmation from the developer that upgrading Zotero 4 for Firefox to Zotero standalone 6 should be fine https://forums.zotero.org/discussion/95892/. Meanwhile, I also need to migrate the preferences and profile (not just the data directory and zotero.sqlite) of Zotero 4 for Firefox to the relevant folder of Zotero 6 portable (from U:\PortableApps\FirefoxPortableESR\Data\profile to U:\PortableApps\ZoteroPortable\Data\Mozilla\Profile), so I'm wondering how to easily do it without manually setting Zotero's preferences one-by-one in the UI window (when eyeballing two preferences UI windows of Zotero 4 and 6, and copying the checkboxes & text fields from one preferences UI window to the other).

    I noticed that some preferences of Zotero 4 for Firefox are stored in U:\PortableApps\FirefoxPortableESR\Data\profile\prefs.js, which also contains quite a lot of other settings for Firefox portable and other extensions. However, preferences of Zotero 5 & 6 are stored in U:\PortableApps\ZoteroPortable\Data\Mozilla\Profile\prefs.js, which doesn't contain too many stuffs other than those related to Zotero.

    So how can I migrate the preferences of Zotero 4 for Firefox to another location for use with Zotero 6 (without setting them one-by-one manually by eyeballing 2 UI windows)? When you originally develop the first several test versions of Zotero 5 standalone portable, how did you migrate all the preferences of Zotero 4 for Firefox (portable) to Zotero 5 standalone portable? And if I open U:\PortableApps\ZoteroPortable\App\AppInfo\Launcher\ZoteroPortable.ini and modify the CommandLineArguments line to CommandLineArguments='-profile "U:\PortableApps\FirefoxPortableESR\Data\profile\" -datadir "%PAL:DataDir%\profile"' (after copying all contents from U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\ to %PAL:DataDir%\profile which is U:\PortableApps\ZoteroPortable\Data\profile), will that work?

    I have this concern because for Zotero Better Bibtex, its preferences UI window & tabs contain too many options to manually set one-by-one, and I have too many automatic export in Better Bibtex, which is impractical to manually set one-by-one. It seems that Better Bibtex has a better-bibtex folder and several betterbibtex.sqlite.bak-like files under my Zotero data directory U:\PortableApps\FirefoxPortableESR\Data\profile\zotero. If the automatic exports are stored in these files & folder, then probably it's OK to simply copy all the contents from the old Zotero data directory to the new one for Zotero 6 (but please correct me if it's not the case). But if the automatic exports are stored in somewhere else, it would be a nightmare, and I've no idea about how to migrate them...

    Sorry for the delay, I was very busy.

    No. This sources are for Firefox and Thunderbird Portable, I don't know how to do this with Zotero, and at the moment you cannot install a second profile this way.

    | So how can I migrate the preferences of Zotero 4 for Firefox to another location for use with Zotero 6 (without setting them one-by-one manually by eyeballing 2 UI windows)?

    Well, there's not a lot of preferences for Zotero... So I would incline for setting them manually, since I don't know if there's a real compatibility between Zotero 4 and 6 on all preferences...

    | When you originally develop the first several test versions of Zotero 5 standalone portable, how did you migrate all the preferences of Zotero 4 for Firefox (portable) to Zotero 5 standalone portable?

    I didn't migrate any preferences. I did it by hand.

    | And if I open U:\PortableApps\ZoteroPortable\App\AppInfo\Launcher\ZoteroPortable.ini and modify the CommandLineArguments line to CommandLineArguments='-profile "U:\PortableApps\FirefoxPortableESR\Data\profile\" -datadir "%PAL:DataDir%\profile"' (after copying all contents from U:\PortableApps\FirefoxPortableESR\Data\profile\zotero\ to %PAL:DataDir%\profile which is U:\PortableApps\ZoteroPortable\Data\profile), will that work?

    Well, here you're not talking about Zotero preferences but about a plugin preferences... You should see with the Better Bibtex dev, I don't use this plugin myself.

    Testing, Go official?

    I gave this a go in Win7 in a clean VM and don't see anything left behind other than the usual Windows tracing bits, so we're good there. I think we should portablize additional paths within prefs.js. And it looks like extensions.json isn't being portablized. I can add these for release easily, so not a big deal. Otherwise, would you be comfortable with this going official?

    Hey John,
    Oh gosh, yes... I see hardcoded paths in extensions.json and in prefs.js But I don't really know how to modify this? I guess it should be done by an nsi script?
    If you're willing to do it, I'm all for it, since I don't really understand nsi...

    Of course I'm okay with making it official! How should we proceed? Will I still be involved in updating?

    It's handled in the launcher ini. For example, this handles relative paths all the way to the drive letter in prefs.js:

    The current entry only handles a single path. If something else drops a different path in there that's not the Data\profile path, it won't be adjusted.
