ARC File Format

LH ARC (old version) compressed archive

ARC is a file extension for a compressed file used primarily by DOS. ARC stands for ARChive.

ARC files can contain either a Macintosh HFS archive, or an MS-DOS archive. No longer commonly used due to the outdated compression algorithms, there are many utilities that will open these files, including WinZip, and Macintosh Stuffit.

MIME type : application/arc, application/ArcMac

I noticed these rather LARGE files in a group of 8, and doing some disk space "housecleaning", wanted to see if these files were of any critical nature to the operation of my computer - so I could back them up and re-claim the workspace. That's all. I've backed them up, wiped them from the drive, and I'll let you know if there are any catastrophic results...however, I will make no further entries if the computer operation is NOT affected by removing these files.
