File properties

[tfs]

Is there a way in asp.net to get the file properties such as: author,
subject,title and category. Apparently, fileinfo doesn't have that.

I need to get the these as we are going to use them for our document
display system.

Thanks,

Tom

For Word and PDF documents, these properties are part
of the file data itself. You should look up the documentation
on each format to extract the info.

On NTFS file systems, this data can sometimes be found in
a so-called "named stream" inside the file (I know it exists with RTF
and graphic files).

To find out more about this last type of data, there's a
free utility, available at:

I hope this helps you...

I tried that, but it doesn't seem to show the alternative data stream for a
..doc file - which is where the title, subject and category are. It does
show the security and object identifiers types (both unnamed). It does show
the alternative data streams for rtf files (summary and document), however.

No, as I said, the info for doc files is inside the file itself.

More information about the doc file format (and others) can be found here:

You're right.

I must have missed it.

Thanks,
