Does the “Clean Up” Function Remove Only Definition Files in the Module Update Folder?

Overview

This article explains how the Clean up function in Settings > Module Update behaves and whether it affects non-definition files stored in the same directory.

How the Clean Up Function Works

Cleanup applies only to official OPSWAT update packages downloaded by the Update Downloader.

Each update package includes a YML file with a timestamp embedded in its filename, for example:

ds_3_windows-database-1553828845-1555551582691.yml

The cleanup logic evaluates this timestamp. If the timestamp is older than the configured cleanup interval, the Update Downloader removes:

  • The YML file
  • The corresponding ZIP file for the same package

The process does not rely on Windows “Date Modified” or file creation dates, only the timestamp inside the filename.

Which Files Are Affected?

Files that may be deleted

Only valid OPSWAT update packages that follow the expected filename pattern containing a timestamp.

Files that will NOT be deleted

Any file that does not match the update package naming format, such as:

  • readme.txt
  • custom_config.yml
  • manual_backup.zip
  • notes.docx

Even if the file extension is .yml or .zip, it is ignored unless the filename resembles an OPSWAT update package with an embedded timestamp.
