Thanks for your work on this JW and welcome to the development team Smile

As mentioned, I cleaned up those couple bugs and recompiled with PAL 2.1b2 to get the proper name to show up in UAC. I did language switching, too, but it won't work yet due the language filenames themselves being localized (Chris is working on a fix for PAL).

Nice looking app,

only i dont see my own flash drive to defrag (someting i would like)
nor i cant uninstall the app ( Uninstall of %APPNAME% failed )

maybe some1 got sugestions to do 1 or the other Smile

Defragging flash drives is not only unnecessary, it will decrease the life of your drive. Defragging is only useful for hard drives, not electronic memory storage.

This is probably why the flash drive doesn't even show up.

1. Flash drive are not supported for this program from what I can see from the program and from the official site, it dose not give support for flash drives. Sorry for that.

2. Applications do not need to be uninstalled the can be deleted like any other file.

But just in case what do you mean by

nor i cant uninstall the app ( Uninstall of %APPNAME% failed )

You can "uninstall" by right-clicking in the menu and selecting uninstall. I don't know under what circumstances, but sometimes it'll give that error stating that the "uninstall" failed.

As BuddhaCha stated, Flash drives probably aren't supported for a good reason, so I don't think there's anything to apologize for. People shouldn't be trying to defrag their flash drives, simple as that.

I like the real-time background defragging feature of this app, a rare feature among free defraggers. I tested this during the development phase and it seems a good quality apps. Thanks for bringing it to PA.c!

The ability to defrag a flash drive can be enabled in Options. It is disabled by default because you should *not* be doing this.

If Uninstall failed, it's because a file was locked. Could you check with Unlocker or similar to find out which one?

Well JKDefrag is really a Windows 32bit console application (it doesn't have a grahpical user interface), but Travis wrote a GUI for it. SmartDefrag is a full Windows applications with a GUI. From that perspective it's a little more user friendly and polished.

However, from a functional standpoint there seems to be little to choose between them. JKDefrag's optimization/defrag processes are a little more transparent because the author took some time to explain them in detail on his website, but the products are functionally equivalent.

SmartDefrag has a slight edge with it's always-on defrag that runs in the background, intelligently defragging your harddrive while your computer is on. It typically runs when your computer is idling or using very little resources. I've used it as I've worked at the computer and haven't noticed any performance loss. Naturally, you also have the option of not running this and just performing on-demand defragmentation.

So I think it really just comes down to personal preference. You'd really have to test both extensively, side-by-side to see which is "better". I'm guessing there wouldn't be much in it.

Thank you for the information. You seem a little more familiar with Defragging software than I am, so may I ask you one more question? How would your compare these two portable applications with an installed application such as PerfectDisk (in terms of effectiveness)? Thanks again.

I'm familiar with them because I've used them and made casual observations about how well they work or not. However, measuring the relative effectiveness of them is actually pretty difficult, and to get a true measure you would need some kind of scientific test. For the most part I think they rely on Windows APIs, so they all work off of the same base functionality that is part of the operating system itself. Obviously, how those APIs are implemented can vary and consequently some will perform better than others. However, this is much for muchness.

I'm not familiar with PerfectDisk, but perhaps you're really asking two questions in one:

  1. Are freeware/open source defragger better or worse than commercial counterparts?
  2. Are portable applications better or worse than installed applications

For number 1 I would respond that yes, some freeware/open source software is of questionable quality, but then so is some commercial software. To support my statement I would cite anti-virus software of which there are some notable free options that are just as effective if not more so then their commercial counterparts. Same applies here in my opinion.

For number 2, I would make a case that portable versions are actually better since you can run them independently of the drive you are trying to defrag. It means that the defrag/optimization can run more thoroughly or completely. The key point is that you don't lose anything by running a defrag program portably. It doesn't somehow diminish its effectiveness, with the possible exception of if you try to defrag the flash drive that the portable defragger is on, which you shouldn't be doing anyway.

I don't claim to be an expert on the subject but I've been using defraggers long enough to know what works and what doesn't. The default Windows defragger for example, doesn't.

I don't mean to be one of those guys but I hate that last bullet point. When I see something like this I assume it means GPL which would guarantee rights to the current version of the software code forever. I came close to tainting my portable apps install after taking pains to purify it. Luckily I double checked the bottom of the download page. I do wish there was some easy way to know what is open source from the news page. It would save me a few clicks every so often.

This is clearly mentioned in multiple locations. The end of the first paragraph of both the news story and the app's homepage says "It's freeware for personal and business use." The news story is categorized as "Freeware Release" which appears at the bottom right of each news story before the comments. And the page has the license detailed under Download Details. Additionally, "(Freeware)" appears after the app name on both the main Portable App Directory page and the Utilities sub-page. This is consistent with all other freeware releases.
