Running from R/O source

Hello,

I've tryed to install filezilla portable on a network share where users have only read access.
I've copy the file filezillaportable.ini in the same directory as the launcher and change the setting "SkipBackups=false" as explained in the read me file.

But I've always errors saying that the files *.xml could'nt be writen ? ...

Please help ...

Thanks in advance.
