### file extension - DoubleSpace compressed volume

What is ### file? How to open ### files?

File type specification:

Archive and compressed file type

The ### file extension was related to DriveSpace. Also known as DoubleSpace, it was Microsoft's disk compression software.

It was included as part of Windows 95, 98, and Me, as well as DOS 6.20 and later. The latest version in Windows 98 and Me was version 3 (DriveSpace3).

Disk compression software compresses data on the fly when the data is to be stored on the hard drive or a floppy, and expands the data as it is read from the drive. The process happens in the background, and is transparent to the user.

With DriveSpace, compressed drives are actually one large hidden file on a host drive. For instance, if you compress the C: drive, you will find a Drive H on your computer afterwards. This drive will appear to have no space on it, since the hidden file (which you will not see, of course) is actually taking up all the space.

This ### 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.
