Repair And Unpack Compressed Archives With AutoUnpack

It happens quite so often that a set of downloaded archive packages carry voids, incomplete binaries and other problems which thwarts user to unpack the archive correctly, if you’ve faced such exceptions in the past while extracting compressed archives, you should consider giving AutoUnpack a shot. It is a Windows application which uses PAR2 mechanism (famous successor of PAR1) to verify completion of downloaded files. When there are some incomplete binaries, it will promptly fix and fill the voids from PAR2 blocks to unpack/extract all the contained content. Another noteworthy build-in feature is auto-removal of all the sources – RAR, 7z, ZIP,TS, etc., after unpacking of corresponding archives is successfully completed

To start, you need to specify archive folder (source) and a location where archives are to be extracted. It consistently monitors the source folder for archives, on finding a new archive in specified source folder, it will start listing them down in the main interface. Since it processes all the archive in top to bottom sequence, you have options to sort the list in different orders. Once done, click Start to begin unpacking the archives.

By default, after all the archives are processed (unpacked or repaired), it moves them to Recycle Bin. The application is highly customizable in terms of features’ behaviors, you can change this removal behavior and customize other general options from Settings window. Since it is largely built to repair archives, it maintains a detailed list of statistics and history of all the processed files to review the errors it encountered during repairing the archives.

    • Google the program name and version and there are a bunch of freeware sites that have it available.

      On the other hand, I tried this on Windows 7 Ultimate x64 and frankly it just didn’t work as advertised – it ignored the output folder and used the source folder, and for some reason, the “empty recycle” bin froze. After restarting Explorer.exe I tried again with this app still running and it again froze. Restarted Explorer.exe, killed this app, and recycle bin was fine. Not sure it is just related to x64 or not.
