.ORIG File Extension
What is an ORIG file?
An ORIG file is a file that may have been created by various programs. It stores a backup copy of a file, which has been renamed with the .orig extension so that the user knows it is the original. ORIG files are most often created manually by a user rather than by a program.
When creating ORIG files, you should name the file in such a way that it is easy to remember what file type the original file is. For example, when backing up an XML file, you may use the compound extension ".xml.orig" so that you know it is an XML file.
NOTE: Original files also use the .ORI extension.
