Why 31 char limit on remote file names?

I noticed that the Finder still seems to enforce a 31-character length limit on file names. Why would that be the case, even if the remote volume is served by a Mac OS X machine? What kind of a hold-over from pre OS X times is that?

I don't know exactly, there's the same limit on idisks.

(no problem on a local volume for a name up to 256 characters)

Stupid OS9 left overs that I mentioned over a year ago and are still around.

It's not the case - we have absolutely not problems with long file names on our Xserves with Mac OS X Server 10.2.x.

How are you accessing it?

I'm having this exact same problem right now. I have a G4 Cube running OS X server. If I change the filenames from the Cube, everything's OK. But if I access that drive via AFP from my 17" Powerbook, not only can I not have more than 32 characters, I can't use Japanese characters! I found this out the hard way when a slew of my iTunes files and folders changed - Japanese names became ?????????.mp3 and "Singers and Songwriters, 1973-1974" became "Singers and Songwriters, 19".

I would guess the char limit is still around for AFP volumes because the OS X machine you are sitting at doesn't know for sure whether it's talking to OS X or OS 9 and doesn't want to violate OS 9. Just a guess.

That's what I thought. So what's the solution?

Looks more like a problem with the finder than with AFP - if the 31 character limit was in place then all folders and files would be shortened automatically.

Perhaps it's just a glitch with the finder and mounted network volumes?
Computer thez nohhh...

Again, we have no problems, and the Sharepoints are AFP volumes.

AppleTalk is turned off on the servers btw.

My Xserve doesn't give a darn about OS9 filename limitations. It's happy to serve up 40 character filenames that 9 truncates with that #DF32L type ending.....

Not true. I can easily make a file with a far longer name than 31 chars and put that on my iDisk. The name doesn't get shortened.

We always were talking about renaming a file to give it a name with more than 31 characters, while it is already on the remote volume.

I didn't say I mentioned it to Apple, I started a thread here and it is a widely reported problem since OSX 10.0
