Setting Mac OS File Type & Creator

[Martin Baxter]

Dan,

Under OS9 and earlier the type and creator are stored by the finder in a 
hidden file on the disk where the file resides. So forget the resource 
fork. Res Edit just sets the finder information in this case.
You can set the global filetype property in rev before writing the file. 
Once the finder has this info about the file, it will then be copied to 
any mac media that the file itself is copied to. To transmit the file 
via a network with this data intact I suggest zip or stuffit, both of 
which should keep type creator info intact.
