Access Record-Locking File
Every Access database version uses a lock file that prevents users from making a modification on the same record simultaneously. This Access lock file doesn’t contain any data and can be deleted by itself when the database is getting closed. In some cases, this file doesn’t delete itself. When you try to attempt such delete procedure you may encounter issues like “cannot delete Access record locking file”. and further your database continues to appears locked.
In the newer Access database version, the default Access file extension is accdb. it’s lock file shares the same name and location the same as the main access database file but having extension LACCDB. But the older Access database version like 2002/2003, these extensions are MDB and LDB.

Well, you can see this file in a plain text editor using some editors that might return odd characters. So, make use of the MS Word instead of the notepad and you will see machine and user name listed for members that are currently using the Access database file.
When the last users using the Access database closes down the shared Access database, it will automatically remove Access database lock file. but some time it won’t delete itself and you need to delete it manually. So, that you can use your Access database without any restriction.
Why You Can’t Delete Access Record Locking File?
Whenever the last user of your Access database closes the database, the respective ldb/accdb file is gets deleted. But the problem arises when a user doesn’t have such rights to delete such a lock file or when the Access database is getting corrupted somehow.

What Issue Encountered Due To This Ldb/Laccdb File?
MS Access jet database engine mainly uses this lock file information to obstruct users from writing data to pages or records which other users have locked. And also, for knowing which pages and records are been locked.

Meanwhile this lock conflict situation, users encounter “Write conflict“ pop-up message which allows you for saving the records, copy it to the Clipboard, or drop the modification that you have done.
In some cases, users receive the following error message:
Couldn’t lock table <table name>; currently in use by user <security name> on computer <computer name>.
If the .ldb file is get corrupted, then you may see scrambled text instead of user names in the above-shown lock conflict error message.
