If you delete database objects in the Access database or delete objects in the Access Project, the Access database or Access project may be fragmented and the disk space usage efficiency will be reduced. Compressing the Access database or Access project is actually copying the file and reorganizing the storage mode of the file on the disk. Compressing database files can indeed improve database performance and fix database errors. Generally, Microsoft Access database or Microsoft Access project cannot be compressed for the following reasons:

1. the disk space cannot accommodate the original and compressed Access database or Access project versions at the same time. Delete unnecessary files and try again.

2. You do not have the "open/Run" or "open in exclusive mode" Access Database permissions. If you do not own the database, contact the owner to determine whether the two permissions of the database can be obtained. If you have this database, you must have the update permission.

3. Other users open the Access database or Access project.

4. The Access database or Access project is located in a read-only shared network, or its file attribute is set to "read-only ".
