Mailing List Archive: uploaded image file/dir names?

I've posted a question at
http://meta.wikimedia.org/wiki/Talk:MediaWiki_file_usage
which reads as follows. Any hints on this? The webpage seems to be
incorrect. (My reason for looking into this is that I want to do
multiple file uploads, but the 'bot' scheme isn't working for me so I'm
trying to read the code and docs to learn how to automate this a bit
better.)

I'm confused about the image filename hashing. Is the following
statement correct? Filenames are MD5-hashed, and since many filesystems
don't handle large directories well, uploads are broken into
subdirectories with the first and first two hex digits of the hash, eg:
upload/7/79/Wikicontestlogo598932.jpg. I tested this by downloading the
linked-to file. The result was
ee3fe2bfeffd646b0bee15265af96c37 Wikicontestlogo598932.jpg

which should have gone into a directory e/e3 instead of the directory
7/79 as indicated. --DK 18:52, 2004 Jul 21 (UTC)

Oh, lord, I hate to do this but ... I already realized my error.
Please ignore my prior posting. (The answer is that it's the FILENAME,
not the file contents, that are md5 hashed.)

Sorry, folks.
