What is a .LDB file?

A .LDB file is a type of file used by Microsoft Access, a database management program. This file helps manage who can make changes to a database at any given time. When someone opens a database in Microsoft Access, the program automatically creates an LDB file. This file works like a lock, ensuring that only one person can make changes to the database at a time, which prevents any confusion or loss of data that might occur if multiple people were editing the same information simultaneously.

The LDB file also makes sure that when updates are made, they are not accidentally erased or overwritten by someone else. Once the database is closed, Microsoft Access automatically deletes the LDB file, unlocking the database so others can use it later.

You typically do not need to open LDB files yourself. They are handled by Microsoft Access in the background. However, if you are using Microsoft Access and need to know which program can interact with LDB files, it is Microsoft Access 365.

It's important to note that LDB files are directly linked to the database they are locking. They have the same name as the database file (which usually ends in .MDB) and are located in the same folder as this database file. This setup helps Microsoft Access keep track of which database is open and needs to be locked.
