.GZ2 File Extension
File TypeMisnamed BZ2 File
What is a GZ2 file?
Compressed file that actually should use the .BZ2 file extension; used on Unix-based systems and mistakenly named with the ".gz2" extension, likely because the user thought it was related to the .GZ format; should be renamed as a ".bz2" file and opened with a bzip2 compatible utility.
NOTE: GZ2 files may also be seen with the compound .TAR.GZ2 extension.
