How To Fix MS Access Could Not Lock File Error?

Let’s know what fixes you can try to resolve MS Access Could Not Lock File Error.

1: Delete Lock File

MS Access lock files (ldb) are one such temporary file that gets created each time with the creation of a new file in the Access database. It automatically gets deleted by itself when you close your MS Access database program.

But sometimes they don’t get deleted by themselves and this raises problems like Access could not lock file.

Workaround:

When these stubborn Access lock files won’t get deleted by itself then you need to delete it manually.

For this, you have to search this MS Access locking files in your entire hard drive. You can easily recognize it as they have .idb extension.

In the search criteria type *.ldb and delete all the .ldb file you get. This will surely fix MS Access could not lock file error.

2: Prevent Opening Of Access Database In Exclusive Mode:

Another very obvious reason behind this Access database could not lock file error is that your database is opened in exclusive mode.

Chances are high that some other user has opened your database in exclusive mode and making modifications like as modules editing.

Workaround:

Close your Access database completely and once again open it normally without choosing the exclusive mode option.

3: Convert Old Access 97 Version Of The MDW File To New

Note: This solution is applicable to MDB files, not the ADP or the ACCDB files.

If your Access database is not opened exclusively then another reason behind this Access could not lock file error can be:

  1. If in case the two instances of MS Access (DAO database engine) are using diverse system MDW files then this will create confliction.

In this situation, the database starts appearing exclusively locked by some other instance.

  1. MDW file, which is used by your MS Access instances, can easily be checked in the VBA codes by checking the DBEngine.SystemDB value.

Copy of MS Access or DAO may have opened your database using another MDW file and thus this causes the conflict. This issue may be raised in the MS Access instance, VBA Add-in, MS Access add-in, or library reference. Or with some other application program like VB6, .NET, etc. which is being connected with the database.

workaround:

To avoid such a situation, ensure that your entire MS Access instance is pointing to the same MDW file mainly if you are using the workgroup security.

It is also defined within the shortcut used for launching MS Access.

Or when you are trying to open the Access database programmatically, within the VBA code.

Convert Old Access 97 Version of the MDW File

If you are using Access 2000 or its later version, then chances are high that you are still using the MDW file in Access older version. This generates Access database error could not lock file.

As we all know Access 2000 has come up with a new file format i.e MDB.

You can say “MDW” is an older Access database file format just like the latest Access database (mdb or accdb) file format.

Even though the latest Access database version can also open the older Access 97 database version files. But for this you need to convert them, here are the steps that you need to be followed:

  • Create a complete backup of the MDW file that you have.
  • Now try opening the MDW database in your Access application.
  • If your MS Access file is in Access 97 format then your Access application will ask you for converting this to the latest MDB file format.
  • After making the conversion, now you can freely use your new MDW just like the workgroup security file.
