File type specification:

Graphics file type icon Graphics file type

pac file icon: pac filetype icon

File extension pac was used for a special Atari ST graphic format called STAD.

This format contains a header followed by a single block of RLE-compressed image data. The header is seven bytes in size and contains only information necessary to decompress the image data.

The Atari STAD pictures are viewable in XnView photo editor and manager.

This pac file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
