The name field should always be filled in with an extension that can be
used to identify your data. Name should be considered a required field. If
no name is given, the system will give your data the name "Palm.exg". The
reason that Name is so important is that on non-palm systems - like
windows, name is the only field recognized. If you beam your data to a
windows machine, it must have a filename. If you receive data from a
windows machine, it will only have a filename.
The built in apps support the following filename extensions:
.txt -- memopad
.vcf -- address book
.vcs -- datebook and todo
.prc,pdb,.pqa --- Launcher
The type field is not currently transmitted over IrOBEX when you beam data.
So the type field will always end up as NULL on the receiving device. The
built in applications do not currently register for any types. These are a
bugs that should be fixed in some future PalmOS release. The correct thing
to do is to send both type and file information. The type field should
contain standard MIME types for data.
If you specify a creator, the creator will take priority over the other
settings. Creator will only work between two palm devices. In general you
only need to use creator if you want to force data to go to a particular
application.
