Backup of a hard disk created with Norton Ghost; created when a backup is split into multiple files due to the 2GB file size limit in DOS; other parts of the split backup have extensions ".002," ".003," etc.
Split backups created with Norton Ghost also include a .GHO file, which contains information about the backup files and is necessary for restoring the backup.
First file of a split archive created with various file splitting and joining utilities; used for splitting large archives into smaller, more manageable files; can be used for saving files onto multiple floppy disks or CDs, or for creating smaller e-mail attachments.
Other parts of split archives use the extensions ".002," ".003," etc.
NOTE: Programs such as 7-Zip use compound extensions for split archives. For example, 7-Zip creates split archives with the .7Z.001, .7Z.002, etc. extensions.
Fax image file created by various fax devices and software programs; may contain the image of the first page of a multi-page fax, while subsequent pages use the extension ".002," ".003," etc.; used to store the image data from received faxes.
Saved game state created by Snes9x, a Super Nintendo Entertainment System (SNES) emulator; contains a game snapshot saved in the second of nine slots (slots 1-9); used to save and load SNES emulated game states.
Saved game slots 1-9 correspond to file extensions ".000" through ".009" on the Windows version of Snes9x. Their files are named using the ROM name followed by the respective slot extension. For example, GameA slot 2 would be named GameA.001.
Saved states are stored in the Saves directory of an Snes9x installation. On Mac versions of Snes9x, saved states use the the extension .FRZ ("frozen" states).
NOTE: Unlike a normal game saved state, which may only be created at certain points in the game, 001 files can be created at any time during gameplay.
Backup of a project (.MFA) file created with Multimedia Fusion, a game development program; generated by the program's Autobackup feature; allows the project to be restored in case the original file becomes corrupted or is accidentally deleted.
NOTE: Multimedia Fusion may create multiple backup files with the extensions ".001," ".002," etc, depending on how many backup copies have been selected in the program preferences.
