Preconditions and environment

• Magento version 2.4.7

Steps to reproduce

When using file mode in the file lock provider, the system does not remove the file after use. If there are many variations of the cache hash, the directory size can become very large.

Expected result

The directory where cache files are saved should be small.

Actual result

If there are many variations of the cache hash, the directory size can become very large.
