  --- BEGIN ISSUE ---
  file:// sync deletes files from directory
  **Version**
  Pulpcore 3.39
  
  **Describe the bug**
  When syncing file:// repositories, files are disappearing after the sync.
  
  **To Reproduce**
  1) Copy these two repositories to the FS:
    - https://github.com/Katello/katello/tree/master/test/fixtures/test_repos/file1
    - https://github.com/Katello/katello/tree/master/test/fixtures/test_repos/file2
  2) Sync one, then the other
  3) See that some files disappeared.
    - In my case, file2 lost every file except PULP_MANIFEST
  
  
  **Expected behavior**
  No files disappear.
  
  **Additional context**
  This also occurred with RPM content type files.
