    Try un/compressing a 4GB zip or rar with any program other than Winrar.

    I use ALZip. It does all the normal things you need and it's free. 7zip works, but it always seemed clunky to me and ALZip seems very clean. They both get the job done though.

    In my experience Winrar is the only one the doesn't fail doing so.

    Most other un/compression apps will fail at this 70% of the time, and just leave you with corrupt files or just won't finish the process.

    As far as I know, winzip is the only one that can't do it. I'll try though.
    Pretty sure I've done it before with 7zip with no problems. I'll try again though. It's definitely a valid point, so worth testing.

    Yea, let me know the results as I don't think I tried 7zip for heavy use like that.

    I know Winzip, TUGZip, IZArc, Quick Zip, failed me.

    I'll wait to see what Jalf has to say about this. I'll wait before I switch over to 7zip.

    First results are in (on my T60, 2GB RAM, Core Duo 2GHz)
    The files I'm compressing is a bunch of CD images (.iso, .mdf and a few others, I just grabbed enough to get over 4GB)

    7zip (solid archive, normal compression, .7z format, multithreading on):
    Worked fine. No problems with file size > 4GB
    Uncompressed size: 6.19GB
    Compressed: 5.43GB
    Time: 39 minutes

    Running the same test with winrar and .rar file now.

    (I should probably mention that the main reason I prefer 7zip is... I like the icon better... Always hated how ugly the winrar icon is... Bunch of purple and green books, wtf? Looks like something from Win3.1. Call me weird, but that sort of stuff can really annoy me :D)

    Edit: Preliminary result:
    Oof, Winrar is definitely more CPU intensive... On the 7zip test, I really didn't notice it running in the background (both are set to run at high priority). With Winrar, my computer is sluggish as hell. Interesting to see if that makes it finish faster as well.
    Edit2: Well, passed the 39 minute mark, and WinRar is 51% done. Looks like we're in for a long haul here...

    WinRar (solid archive, normal compression, .rar format, multithreading on):
    Worked fine. No problems with file size > 4GB
    Uncompressed size: 6.19GB
    Compressed: 5.43GB
    Time: 81 minutes

    So, same compression ratio on the files I tested with, both can handle large file sizes. But 7Zip is about twice as fast, and uses less CPU to boot. (When I checked task manager, 7z used around 70%, while WinRar was 85-95%, and subjectively, it was a huge difference. I didn't notice 7z running in the background, while everything became sluggish with WinRar.

    Thanks for the information, Jalf! I'll give 7zip a try.
