Everything is in the title : I've got a smb share with write access on a FAT32 file system (I'm aware of the 4GB limit).

I've got 426 GB free of 736 GB shown on the network drive.

Still if I try to upload a medium sized file (94MB) I've got the error :

The file 'fileName.extension' is too large for the destination file system.

Do you know what can cause this error ? (maybe a by user quota ?)

And do you know how can I avoid it ?

The smb server is running on a Debian based ARM linux (Cubian on cubieboard) I access it on my Windows 7 64 pc.

I've install the samba using packages: samba samba-doc samba-common smbfs smbclient and adding in /etc/samba/smb.conf :

path = /folder
comment = comment
writable = yes
browseable = yes
public = yes

Edit :

Here is the output for cd /media/path/ ; df . :

Filesystem     1K-blocks      Used Available Use% Mounted on
/dev/sda2      771772352 324799744 446972608  43% /media/MULTIMEDIA

Edit 2 It appear that the file name being too long was the cause of this. (Same file with shorter name works fine) So I update my question : What is this filename length limitation about ? Does it take the full path into account or just the filename itself. and what it the actual limit ?

Thanks to commenters anyway :)

"4726 GB free of 736 GB"? – That Brazilian Guy Jun 27 '14 at 14:27
from the server, whats the output of cd \path\to\upload\dir ; df . – Frank Thomas Jun 27 '14 at 15:10
I've edit the mistake 426 Go of 736 ;) – Guian Jun 27 '14 at 17:30
I dont know what a samba is, But the error looked to me at first that the files name itself is to long, for the file system, not the data size? – Psycogeek Jun 27 '14 at 20:14
You're right... 0kb file, very long name : same error. 94Mb file short name : copy without error. Would you explain us What happens here ? – Guian Jun 27 '14 at 20:56

Check this table in the Wikipedia:

In the Limits section, you will find that the maximum filename length is 8.3 for FAT32 file systems.

8.3 filenames have at most eight characters, optionally followed by a period "." and a filename extension of at most three characters. For files with no extension, the ".", if present, has no significance (that is, "myfile" and "myfile." are equivalent). File and directory names are uppercase, although systems that use the 8.3 standard are usually case-insensitive.

Just in case you are wondering, apparently there's no length limit for the path, though.

I would add, it appear that special characters are longer than normal ones : a space or a 'é' are considered longer than '_' or 'e'. So we should avoid those characters in filenames. – Guian Jun 29 '14 at 16:24
