Thanks Ursidours for the report.

File operations always raise a ENOENT error when a file doesn't exist.
Checking the file exists before the operation adds a race condition
condition where the file could be removed between operations. As the
operation already raises an error on a missing file, avoid this race and
avoid checking the file exists twice. Instead only check a file exists
by catching the ENOENT error.

Fixed a failure on Windows.

Fixed #26679 -- Documented which methods are disabled on RelatedManager if there's an intermediate table.
