LibTar iconTAR ("tape archive") files are a way of archiving several files in one single file. The tar format is widely used in Unix and Linux operating systems. It does not compress the files, however popular compression tools like WinZip can read and write tar files.

With LibTar you can read and write tar files from your Delphi application, i.e. you can list and extract the files in a tar, and you can create new tar files.

NOTE that filenames in tar can be up to 100 bytes long. LibTar does currently not support the ././@LongLink records that allow files in the tarball to have longer filenames.
