Repair a Broken ZIP or RAR Archive ?

As in my previous post I have provided a solution for extracting files from CRC broken zip files, and maybe checksum error as different applications shows different errors like some will also show writing error but that's different problem.

Problem occurs when a zip file is completely download but doesn't open or act like a corrupted one. I have downloaded a game and after completing the download, I can't open the file using any app. Its like program cannot excute any command from the zip file even it is completely downloaded.

Sometimes its just pause-resume problem, sometimes the file may be archived badly etc as many basic errors can cause such problems. But still there's a method to repair the archive without any problem that too using an Android phone.

You can repair the archive using RAR for Android developed by Alexander Roshal. I must say this app is great when it comes to compression or extraction because this app is so powerful in handling many files at once and doesn't waste time like other apps which keeps on holding the extraction process just to gather information of files.

After downloading the app, follow the provided steps to rebuild the archive ;)

Instructions!

  • Open RAR for Android app from app drawer
  • Find the file which is to be rebuild
  • Select the file
  • Now, click on menu and select "Repair Archive"
  • Then a pop-up will appear asking for confirmation
  • Select "OK" and your archive will be repaired
  • Then, the new rebuild file will be stored in the same folder with the name rebuild.xyz.zip or rar
  • Now extract the file and Done!

For any help or enquiries, comment box is open for everyone.

    1. Then either you've changed the directory of the file or it's already corrupted. Repairing only works in the same sectors of the drive where the file is originally created which makes the application to recalculate the CRC values and make a repaired rebuild but in case if you've moved the file to a different folder or it is not downloaded completely then you cannot repair it

    1. I'm sorry to say this but you can't fix that because the file got corrupted somehow when you were downloading it, this could cause by forced interruption of the download or you just closed your downloader application forcefully without pausing the downloading first and the file sector got mismatched in the storage device and now the application cannot calculate the CRC correctly you won't be able to repair and retrieve it. This solution comes handy when the file was working properly before but got corrupted somehow for example sudden removal of storage drive like pulling of the memory card without ejecting it first, that time your application repair it because t already have the sectors stored and it can relocate it to build a newer fresh file

  20. ok, I had a zip file encrypted with a password created by the X-plore app. it works fine. but, when I tested the app security on one of my encrypted zip files by attempting to access it with the Android file manager it corrupted the zip which now says no files. 156megs were zipped. I ran the repair option and it could not see any files or repair it.
    plus it needed to select a file(s) in the zip before it could start the repair.
    it should be able to analyze and repair a zip simply by selecting the zip file I think.

  21. I like and suggest you to try LongPathTool program. It is very helpful for copying/deleting or renaming long path files.

    2. Hey Christian, files downloaded from the internet often shows very low chances of repairing, this method only repairs that has their origin in the same location where you're repairing, the application has no information of the checksum of the files downloaded from the internet and hence making it difficult to repair, the only way remains is to download the files again

  30. I had a zip file containing obb file of GTA SA game, until now it worked perfectly without any problem. But i uninstalled the game 7 to 8 months before and now i wanted to play the game again so i extracted the zip file and after all this time one of the files inside the zip file is corrupted. I tried to repair both the obb file inside the zip file and the zip file also but it didn't work. Now i don't know how i can play the game without an obb file.

  31. I tried repair an iso file for dolphin emulator on my Samsung Galaxy s10e, but it says recovery record not found, and no files repaired. Why is that? Is there any way to fix an iso file without getting that message?

    1. I'm afraid it cannot, RAR files can be repaired to only an extent where you can save some data and not lose everything. I suggest you to download file again and do not externally affect the download process while the file is downloading that way you can atleast prevent files fragmentation.
