Full name?
Since he has his full name in his profile, would it be okay to list his full name on the team page? Or has he previously said he doesn't want that?
That is..
That is fine with I have no problem at all!
Thanks John..
Thanks John and thanks to the rest of the developers and testers for all there help and support they have provided.
Again thank John and thanks to the rest of PortableApps.com for allowing me to become a member and part of the community.
current download..
Hey John the current download link is not working.
Fixed
It's fixed, sorry bout that. Typoed when I did the revision.
typo
The \FreeUPXPortable\DefualtData\ directory is spelled wrong, so if you're using the default locations in the code (and it looks like you are), the settings file in that directory will never get used.
At the ..
At the moment that is not a problem for there is only a empty .ini file. And I do apologize for the mist spelling, just keep in mind that I am Dyslexic.

No problemo
I'm just trying to have the program work correctly. No harm, no foul.
LOL..
LOL man thats not a problem, thank you for pointing it out.
Something wrong
I know this isn't exactly the right place, but I can't find a support forum for this app rightnow.
I must inform you that there appears to be something wrong with this app.
I've tried to compress Firefox Portable and after that I could not start Firefox anymore. So I decompressed everything, and still it wouldn't start. The only solution was to reinstall Firefox Portable once again.
So compression works definitely but apparently it compresses something it shouldn't compress.
B.T.W.:
I've tried it with upx commandline version and that does a good job.
From the early days of portableapps.com I had some app called appcompactor. It uses upx too and it can compress Firefox portable without any problem.
Whatsmore, appcompactor has a nice feature so you can add complete folders to the compactor. Adding file by file is definitely not useful. If you want to compress portable Java that way it takes much too long to add all files separately, so please add this feature (it is already possible in UPX, so it is only a matter of adding the right switch).
And believe me: compressing portable Java really makes a difference, so you should try compression of portable Java.
Don't Do That
If you compress one of our launchers (FirefoxPortable.exe) it'll break. Permanently. So do NOT do that.
This is for *advanced* UPX compression selections on multiple files. It serves a different purpose than PortableApps.com AppCompactor. For what you want to do, you shouldn't use this.
Like John..
Like John said this is not to be used on the Launchers them self's. This is for very advanced user(s). If you are going to use this for compressing an application, only use it the main program and not on the Launcher or it will not work at all.
[Fixed] Updater: Missing DownloadPath.
