    Is there an app that can do this? I am trying to extract petes latest Rom from a rar file he posted but can't extract on my phone and don't have access to a pc right now. What gives? Why would he post in a format that cannot be extracted on the phone itself? I have a hard time believing this can't be done.

    AndroZip, perhaps. But I hear it has issues with large RAR files (100MB+).

    I tried both "unrar" and "astro". I was trying to extract and install a BB rom without using a computer (forgot cable). Nothing worked. I ended up waiting till I got home...

    You aren't going to be able to. RAR is a proprietary compression, and unrar isn't included by default in linux. You won't be able to unrar it using tar commands because they handle different archives. You might be able to compile the source of unrar on your phone if you download it as a tarball, but that's a lot of work and I don't even know if it would work. If you have anyone you can email it to, ask them to unarchive it, and pack it again as a zip or gz (if they're on linux), it might be quicker.

    I still have a hard time understanding why .rar is so widely used. .zip can be opened out-of-the-box on about 90% of the computers in the world (that is, those running Windows). And .7z and .tar.gz have better compression ratios than .rar and the latter is natively supported on Linux. .rar really seems like a useless format to me.

    Partly b/c before 7z and other better formats were available, .RAR was out compressing .ZIP, and allowed for easy recovery to be included when making multiple-part sets. The other part is that a lot of people are set in their ways, or else have paid for a product that they now like to use.

    Back in 2001, for example (when *I* bought WinRAR), .RAR was 10 times better than .ZIP, 7Z wasn't around, and LZH was dying out in the world of Windows....

    Oh, and I am still able to use my license file from 2001, legally, as verified by RarLabs sales dept. last year. In addition, I can use it on my *nix boxes with the *nix versions of .RAR / unrar As long as I am not trying to use them simultaneously on multiple boxes.

    Having to buy a new version of WinZIP every time it came out got old fast. Now that FOSS programs are out like 7-ZIP with native 64bit support, it is still a tough choice, b/c making, testing, and extracting .RARs in Windows is a piece of cake, and the multiple-part file sets makes it a very attractive alternative to using .ZIP / .Z

    I will say, however, that I always install 7-Zip as well, as it has come a long way from its origins as well, and is every bit a robust archiving client as WinRAR....

    I used WinRAR to extract the nandroid ROM, did a great job

    EDIT: Sorry, I totally misunderstood the topic. I used WinRAR on the PC, not the Droid

    As others have said, I don't think you're going to be able to reliably extract large RAR archives on your phone. I've tried every tool under the sun and it just doesn't work. They handle ZIP files with ease, but RAR's are another story.

    He is talking about extracting it on the Droid itself.

    Hmm, yeah, I totally forgot that .rar files can be split into parts. If .7z can't do that I suppose .rar has something on it there.

    I use androzip for all my files unless andro can do it. Sometimes the files r too big though. But I've done all my rooting over the phone without ever usig a computer. Androzip can also creat zip files. I highly recomend it if u download files off of megaupload or rapidshare. I rarely have issues unpacking zip or rar files
