File Extension OLD

File type: Backup File

About the OLD file type:

If Windows cannot find the appropriate program associated with .OLD files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .OLD file extension identifies an old or archived file which is kept on your disk for future backup needs. Many applications or operating systems such as Microsoft Windows may rename system files with a .OLD file extension so they can be retrieved, if necessary, at a later date.

Additional Information:
To access .OLD files you will need to identify which application created the file originally.
