A file with the Z file extension is a UNIX compressed file. Like other archive file formats, Z file are used to compress a file for backup/archive purposes. However, unlike more complex formats, Z files can store just one file and no folders.
Z files can be opened with most zip/unzip programs.
Unix system can decompress .Z file without any software by using this command, where “name.z” is the name of the .Z file so as csv.z
