The problem of database MS Access

[meggings]

When working with the database in MS Access error occurred, a message appears stating that it is necessary to compact and repair the database. But I can't even open a database, because it leaves the error message in the program. What to do?????? Is there a way bring back source file????

Compact and repair a database that is not open

Note: If other users are currently using the database file, you cannot perform a compact and repair operation. While you run the compact and repair operation, no one can use the database file.

1. Start Access, but do not open a database.
   
2. Point to Info, and then click Compact and Repair Database.
   
3. In the Database to Compact From dialog box, navigate to and double-click the database that you want to compact and repair.

it is necessary to clean the mdb file information about the category of users having access to it. This is done by a special utility. or you can use recover mdb online, a very good recovery service
