The Runtime File Manager is a utility to help you recover from a data file error, should one occur. In the Premium version, only the administrator has access to the Runtime File Manager.
Highlight an individual file or use the Tag All button to select all of the files. Then click on the Info button to obtain basic information about each file in the database.
Should the need arise, this utility can fix data file corruptions. Do not be tempted to simply play with these functions unless you have a rock-solid backup of your data. Don't fix what is not broken!
