.A01

If Windows is unable to open A01 files you may not have the appropriate program installed or may have a registry related error. The .A01 extension identifies a section of an archive. When compressing, some archives are divided into a number of files which are then combined, when uncompressed, to get a full archive. Since the .A01 file extension forms part of a sequence, you might expect this file to be accompanied with other files, with names between from .A01 to .A99.. Incorrect associations are the cause of many file extension errors.
