Open LCK File

The LCK extension is a type of resource lock file.

The LCK extension is added to the name of the file being locked, for example to lock a word file with a DOC extension, like the one below, document.DOC, will result in the creation of a document.doc.LCK file, which is responsible for locking the original file.

The application that locks a given file usually keeps LCK active to prevent the original file from being deleted.

This locking mechanism, which uses the LCK extension, is commonly used by database engines, spreadsheet applications, or even office document files.

Locking can also be used when multiple users access the same file.

In such a case, the LCK file has the ability to track which user has access to the file or its part in a given session.

Different applications implement the lock algorithm differently.

LCK files are of the ZIP type and are usually empty, but some programs may store additional lock-related data within these files.

It is recommended that LCK files are not manually edited.
