What is the .SET File Extension?

.SET File Extension Description:

Several software uses the SET file extension but it is primarily utilized by Microsoft Backup for Windows to produce its Backup File Set.

MSBACKUP uses the parameter setup_file to specify the setup file that defines the files to be backed up and the type of backup that can be performed. It creates the setup file when the program settings and the file selections are saved. Setup files must have the SET file extension.

MSBACKUP allows users to back up the files on the disk using three types of backup procedure, namely full backup, differential backup, and incremental backup. Full backup simply backs up all the selected files and marks each file as backed up. Incremental backup just backs up the files that you have made changes to since your last back up and marks them as backed up while Differential backup also backs up the files that changed since your last back up but does not mark the files as backed up.

Files with the .set file extension contain one of the following switches for MSBACKUP to perform its operations:

* /BW - starts the backup process using black and white color scheme

* /LCD - starts the backup process using a video mode compatible with laptop displays

* /MDA - starts the backup process using monochrome display

* /T[D|I|F] - specifies what backup type can be used where D is for differential, I am for incremental, and F is for full backup.

As part of the backup process, a backup catalog is created by MSBACKUP, which contains information about the files you have backed up. When one or more of these files need to be restored, the backup catalog can be loaded so you can easily select the files from the backup set.

Files with the .set file extension also stores the configuration and settings preferences for various programs, which are loaded when the applications are opened. Several programs such as AutoDesk AutoCAD, Corel Painter, XANA Web browser, Nikon Capture, Diablo II, Alpha Five, and the Sibelius music notation software, reference these files. They identify these programs' personalized preferences, thus they cannot be manually opened and edited except through the program itself.
