ERR: Not a Database File in FoxBASE+/Mac
Last reviewed: April 17, 1995

Article ID: Q102457

The information in this article applies to:


 * Microsoft FoxBASE+ for the Macintosh, version 2.01

SYMPTOMS
When you open a FoxBASE+/Mac database, the error message "Not a database file" is returned.

CAUSE
The database was probably subjected to an abnormal shutdown caused by a system error. If a large RAM cache (over 64K) is used, corruption is more likely to occur when a system error is experienced.

RESOLUTION
The following are three possible resolutions:

Attempt to recover the corrupted database (back up the corrupted database first).

Open the database in FoxBASE+ for MS-DOS. FoxBASE+ for MS-DOS can sometimes open databases when other products cannot. Decrease the size of the RAM cache to prevent future corruptions.

If you know the database structure, create a new database with the same structure, and then use the following command to import the corrupted database.

APPEND FROM TYPE SDF
