LCK File

What are LCK files and how to open them

Are you having problems opening a LCK file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a LCK file?

A .LCK file is a Paradox Lock file.

Files that contain the .lck file extension are lock files that have been created by a variety of database software applications.

When a user has a shared database file open on his or her computer and another user tries to open that file, an LCK file will be automatically created. This file allows the second user to view the contents of the database but prevents them from making any changes. This prevents information in the database file from being accidentally overwritten or deleted.

Once the user has closed the LCK file, the file is normally deleted automatically by the software application. These files should not be opened by other software than the database program.

You usually do not need to edit or view these files, as they only contain information usable by the software program that uses them.
