File or Folder Not Found

This error occurs when a target file or folder is deleted, moved, or renamed between the time the sync started and the time the file is reached.

For example, a Sync is processing 1000 files. The Sync generates a list of the 1000 file names and begins processing them. File number 999 is renamed partway through the run. When the Sync reaches file 999, it cannot find it because the name has changed. A subsequent Sync run picks up the renamed file, as long as it isn't renamed, deleted, or moved again.
