What is an OLD file?

An OLD file is a backup copy of a file, such as a .JPG or .DOC file. It may be created automatically by a software program or created manually by a user to indicate that the file is a backup copy of a file.

More Information

The ".old" extension is often placed after the original file suffix of a file when a newer version of the file has been created or saved by a certain program. For example, document.doc.old would be a backup copy of the document.doc file. The ".old" extension may have to be deleted in order for the file to be opened correctly.
