If you exit abnormally from ADMIN, for example because of a power failure or system crash, and you list the database files in the operating system, you may see files with a .deleted extension. This is because when you do any task that involves deleting a database file in ADMIN, AVEVA E3D™ copies the file to be deleted to a new file with the .deleted extension.

When you SAVEWORK, or exit normally which automatically does a SAVEWORK, the .deleted files are removed. However, if there is a problem which results in database files being deleted, and an exit occurs before the System database can be updated with the changes, AVEVA E3D™ will rename the .deleted files and remove the extension, so that the files will still be available.
