Occasionally, when trying to extract a .RAR file with WinRAR, you may encounter an error. In some cases, the error is related to CRC or the MD5 hash check. This means the ID of the file does not match the original. As long as the file is complete, you can correct the issue using the WinRAR application itself.
Open the WinRAR application. Click on "File" and then "Open Archive" and browse to the damaged .RAR file.
Press "Alt" + "R" on your keyboard. This will bring up the WinRAR repair dialog screen.
Designate an easy-to-find location in the "Folder to put the repaired archive" box.
Check the box that says, "Treat the corrupt archive as RAR."
Press the "OK" button. Once it has finished repairing, a new archive will be built and placed in the location you designated.
Tips & Warnings
- If using the WinRAR built-in repair feature does not resolve the issue, you may find success in trying other extraction software.
- If there are files actually missing or incomplete from the archive and you do not have the PAR2 file for the .RAR, the archive cannot be repaired and must be downloaded again.
- Packet loss or memory errors can cause a .RAR to become corrupted during download.
