What is a zip file? A zip file is an archive that contains one
or several compressed files. There are many file extensions for
a zip file. You might find a zip file with the following file
extensions: .zip, .7z, .ace, .arj, .cab, .gzip, .rar, .tar. A
zip file may contain a password and an encryption to protect
sensitive data. You may have come across a self-extracting
archive zip file with the .exe file extension. You will not need
a zip utility program to extract this kind of file as it
extracts itself once you run it. There are many methods for
zipping files - contact us if we haven't covered them here.
