Restrictions for file name length and other

[jaakennuste]

I have some occasional problems, syncing content between my XP home media server and PCH 200 hard drive. I noticed, that it happens with long path names/filenames. What is the max filename length in NMT, are there some restricted chars in filename? Any suggestions?

[halfelite]

linux has no said restriction on path/file name length, you would hit windows limit first which you might have done. as for characters dont have asterisks, backslashes, or question marks, or end a file in a period

Update

Too long path/filename crashes A-300. This behaviour has only remedy -- rename/shorten path and filenames.

Would you like to expand a little? I use A300 and my network PC uses Windows and have not seen any crashes but I don't use long pathnames. What path names are you talking about?

An example would be nice.

Try that: http://isohunt.com/torrent_details/31152...ab=summary

Use local HDD or open it from NAS (do not stream). Try to play it and please share Your experiences.

Do you have a network share to PC or do You stream? This probably occurs only from local HDD or network share.

You have lost me why do I need to download a torrent?

Are you saying that the downloaded FLAC files will not play when placed on your local storage? If so then that is nothing to do with path names and is an issue with filenames or perhaps even the FLAC file itself.

If it is the FLAC file that you cannot play from local storage then make a report in the 300 seri9es Audio Section. Also check filename size in the 300 and 200 section as there have been issues with filename length sizes.

I use Samba shares on both my PC and my Synology NAS/ I also test NFS from the NAS.

Thats one badly named file!!

Just counted one filename at random, its 155 characters long. It also has 'special characters' in it and numerous spaces, commas, and full stops in there for good measure.

wow that is long, once you add the rest of the nmt path to it, it's pushing over 200-250. It seems like bad handling on the pch when path is too long..

[chris57]

Well I tried the files via Samba shares with the files in my torrent directory on my PC. The songs played fine. The embedded cover showed up in the audio player.
I use a direct HDMI to TV connection.

[accident]

You might want to do a little test and keep adding 5 or 10 more characters to the folder it's in to see where the path approximately breaks.. from my googling, it looks lke with smb your looking about 259 being the max windows will handle. of course it shouldn't be crashing the pch so maybe it's just bad error handling where it's not catching the path too long error and then tries to use the file liek it opened it.

[chris57]

I wonder if he's using the cue file that is in the folder?

Cue files are not wokring on the 300. They do/did on the 200 series.

Cris75, no I don't use CUE file, as it does not work (as You already).

I downoalded filest from the torrent, placed it to my DiskStation directory system Music -> Classical -> Prokiofiev -> Romeo and Juliet -> ...... During the playback they crash the system. They actually start playing and in few minutes A-300 will reboot.

Interestingly they didn't cause any problem for You. Just try to play all album, and probably You'll see.

[accident]

ok so your path once you add on the internal pch path just to get to the network does break 259 characters.. yes that's a damn long path.. I agree there is a bug here, it shoudln't be crashing.

[jaakennuste]

Yes, it about path+filename length (directory structure + filename) on local media or NAS, not just filename length. Tested on one piano album, shortened directory name and it works.
