Of course, this is the problem but not the origin of the error.

Removing the first two wrong characters from a DirectoryEntry name,  permit the system to found the relative file.

With not removing the system can't manage the file and after generate the error.

Yes this is the real question.  But i hoped my informations was sufficient for you.

The size of the file is 4096  ( the size of a directory entry on linux )

The copy from the stack of the file is :	 'Mac OS X        	2°â

The methodEntry, 	one   aDirectoryEntry  instance data is:

My configurations is based on local data network where i have two system:

	a MacBook where run:	1) 	Pharo 1.4 for manage the code
							2)  	Pharo 1.1 with GemTools Launcher - >=1.0-beta.8.7  for manage the GLASS repository

	a server based on Ubuntu system where run GLASS 3.1.0.4   and the samba support for sharing the DTRRepository directory  ( where i save the fileTree files )

> What user you are running as for GLASS and Pharo?
	
The glass user is:		 dario

The MacBook link the server volume DTRRepository as:	  guest

> Sample file permissions (ls -l) after a pharo write and after a GLASS write?

After Pharo write the relative ls -l is:
	drwxr-xr-x  9 nobody nogroup  4096 nov  7 14:05 DtrFinanza.package


After GLASS write the relative ls -l is:
		drwxrwx--- 15 dario  dario    4096 nov  8 11:09 DtrCRP.package
 
Ciao, thanks,
