The finder info/attributes are stored in a stream called "AFP_AfpInfo". The default data fork stream is called "$DATA" and any of these can be accessed thus: "c:\filename.txt:forkname". Finder comments are stored in a stream called "Comments".
As a result, ResKnife prohibits creation of forks with the following names: "" (empty string, Mac data fork name),
"$DATA" (NTFS data fork name),
"AFP_Resource", "AFP_AfpInfo" and "Comments".
It is perfectly legal in ResKnife to read in forks of these names when accessing a shared NTFS drive via SMB. The server does not need to be running SFM since the file requests will appear to be coming from a PC. If the files are accessed via AFP on a server running SFM, SFM will automatically convert the files (and truncate the name to 31 chars). */

#warning Note to Uli: how about changing the selector that the plug should implement to -(BOOL)dataForFileExport:(NSData **)fileData ofType:(NSString **)fileType. This is basically a concatenation of the two methods you came up with, but can allow the host app to specify a preferred file type (e.g. EPS) to a plug (say the PICT plug) and if the plug can't return data in that format, that's OK, it just returns the fileType of the associated data anyway. I would also recommend adding a plug method called something like availableTypesForFileExport: which returns a dictionary of file extensions and human-readable names (names should be overridden by system default names for that extension if present) that the plug can export data into, useful for say populating a pop-up menu in the export dialog.
