But os.chmod() could surely be used as a "best attempt" to make the files readable and writable -- in this case by clearing the Windows read-only attribute. (And I agree, if any filesystem-specific attributes were involved, I would shut my mouth now.)
If using os.chmod() to grant RW permissions failed for a particular setup, no-one would be any
worse off, but in many/most cases where:
a) I have RW access to the auto-add directory so I can add files and see if they are still there later,
b) I'm running Calibre from an account which has RW access to the auto-add directory so Calibre can import the files and delete them,
c) I put files in the auto-add directory because I want the files to be imported by Calibre if at all possible, and
d) only the common read/write attributes need setting for this to happen;
... it should work, and then I would be much
better off... wouldn't I?
