Hello.

In my dissector, a user has to define a network path, in which some text files
are saved. Therefore I am using the function
‘prefs_register_directory_preference( )’ to get the path to a folder.
I also searched for the difference between UNIX and WIN network path names and
noticed, that WIN uses the backslashes (e.g.: ‘D:\Development\...’ ) and UNIX
the slashes (e.g.: ‘…/Development/…’ ). 

Before using Wireshark 2.1.0 everything was fine with this functionality. The
path was correctly been given to the program, for example for my windows pc
‘D:\Development\files’ (backslashes). Since I have upgraded my patch up to
Wireshark 2.1.0, I still use the same function, but in comparison, Wireshark
now returns for the same machine ‘D:/Development/files’ (slashes). 
Even the protocol ‘MATE’ also uses the preference functionality , to define the
path to a special file. But also there, the same problem appears.

For explanation:
I am using this path, to find several different files in this folder, which are
including important information for my dissector. Therefore I add (depending on
the operating system)  \<filename> for WIN or /<filename> to open the file and
to search for the information in it. But getting the path
‘D:/Development/files’ from Wireshark I’m adding for my windows pc \<filename>,
which gives me the total path to the file ‘D:/Development/files\<filename>’.


Alexis La Goutte told me to report this to bugzilla, so I hope it will help
you.
