The file extension BKP is used by several programs that create automatic backups of files that would otherwise be overwritten or eliminated. The BKP extension is typically appended to the end of the backed-up file's original file name; for instance, if a program automatically creates a BKP file for a data file, called "example.dat," the BKP file will be named "example.dat.bkp." This naming convention makes it very easy to restore BKP files to their original, functional state, as long as the program that was used to create the file is still installed on the computer.
- Skill level:
Navigate Windows Explorer to the folder that contains the BKP file that you wish to restore to operation.
Right-click on the BKP file to open a file options menu. Left-click "Rename" from the file options menu. Doing so will highlight the file name and will insert a blinking cursor that indicates the position in the file name that you are currently editing.
Press the right arrow key repeatedly until the blinking cursor is located at the far right of the BKP file's file name.
Press the "Del" key four times to remove the .BKP extension that was appended to the end of the file. Be sure not to delete the BKP file's original extension if it has been preserved; for example, if the BKP file is named "example.dat.bkp,"rename the file to "example.dat." If the original file extension was not preserved in the file name, you will need to delete the ".bkp" portion of the file name and type in the file's original extension.
Press "Enter" to save the rename operation.
Double-click the restored file to open it in the program that is associated with its restored file extension. Alternately, run the program that was used to create the original file and open the restored file in that program.
