No, I'm not talking of file descriptors, I'm talking of Aliases (and those specifically - not symbolic links). I just checked Apple Developer docs, and they seem to be still available in Mac OS X:
Alias Semantics
When OW would use such an object for storing its Download history, and Hazel performs its move operations in the way recommended in that document (instead of manual copy/deletions - I don't know if it does, but would hope so), OW's entries would still point to the correct file even if Hazel has moved the file after a completed download. That's what I'm after: Having downloaded a file, and having moved it (e.g. by Hazel, or even manually), OW would still be able to perform its "Show" command on a download list entry, as it would be able to find the moved file based on its alias's unique identity component (which is the fallback if its path is no longer available).
Am I missing something?
