Create .taz, .tar.Z TAR Archive

See more Tar Archive Examples

Demonstrates how to create a compressed TAR archive containing an entire directory tree. This example creates a compressed archive using Unix "Z" compression. The typical file extensions used are .tar.Z and .taz. Pascal (Lazarus/Delphi)
