What are LDB files and how to open them

What is a LDB file?

LDB files have multiple uses, and Microsoft Access Lock is one of them. Read more about the other uses further down the page.

Microsoft Access Lock file

The .ldb file extension is used by the Microsoft Access database application to prevent files from being edited by two people simultaneously. If a file is open by more than one user on a multi-user database and both users try to make changes to the file simultaneously, it could result in a corruption of the file and a loss of data.

The LDB file prevents this from happening by locking the file when one user already has it open. The LDB file is located in the same folder as the original file and with the same name, but the .ldb extension is assigned to the file rather than the .mdb extension. Once the user with the edit-enabled file has closed the file, the lock is removed from the file, and another user can open the edit-enabled version.
