What is a .tar file?

A .tar file is a Tape Archive Format. This is an archive โ€” a container holding other files, usually compressed.

How to open a .tar file

  • 7-Zip (Windows) or Keka / The Unarchiver (Mac) extract most archive formats, including old ones.
  • On Linux, try `7z x`, `unar` or Ark.

The registry records this extension against Tape Archive Format, so software from that family is the most likely match.

How to convert a .tar file

  • Extract the contents, then re-compress as .zip if you need to share them widely.

MIME type

When a .tar file travels over the web, servers label it with this MIME type:

application/x-tar
