Fix CRC error when unpacking archives
The following instructions only work with RAR files. If you have a faulty ZIP file, it is usually worth checking the password or downloading the files again.
- Download the "WinRAR" program and install it. The program remains completely free even after the test phase has ended.
- Create a new folder on the desktop and copy the faulty file (s) into it.
- Click the Windows key and "E" at the same time, select the "C" drive, open the "Programs" folder and look for the "WinRAR.exe" file in the "WinRAR" folder. You have found the right file if you can use it to start the program. Copy this file and paste it into the new folder as well.
- Now press the Windows key and "R" at the same time, enter "cmd" and click "OK". A black console opens.
- Enter the following commands one after the other and press the "Enter" key after each command (see image): First, "cd Desktop". Then "cd new folder". Finally "rar e -kb TEST.rar". You must replace the word "TEST" with the name of your RAR file.
- The contents of the archive have now been extracted into the folder.
