Hi,
I'm trying to upload files and to use the revision number field of the file.
By using PostedFile.SaveAs the files are uploaded.
The problem is that the summary tab and the revision number are deleted.
Is this behavior is "by design" or it is just a bug?
Thanks,
Hadar
Hi Hadar,
If you're referring to the summary information included with files like
Word's .doc files, I'm afraid you're out of luck. The summary
information is stored in an alternate data stream, which is an odd
feature you may not be that familiar with. Suffice it to say, I do not
believe any browser will include any alternate data streams when
uploading a file.

Quick summary of alternate data streams: Any particular path may in
fact represent more than one "file". There is one default data stream
(the one you or I would consider to be "the file"), and any number of
alternate data streams. These are accessed by placing a colon : after
the filename, and then the name of the stream you want to access, e.g.
foo.txt:stream2. I believe the summary information is stored in a
stream called ?SummaryInformation, where ? = U+2663, the club (or at
least, that's how it appears on my system)
