FTP Sync and space filename

Hello all,

I'm about to purchase SynbackPro, but I have an issue with FTP synchronization (this is SSL FTP) :
when a file name like

TOP HOUSE 2 (MACHINING) A1.pdf

(with spaces) is involved, the software wants always to copy it to the FTP server !

On the server, the file ends up this way

TOP HOUSE 2(MACHINING)A1.pdf

note that some spaces have been discarded.

It looks like to be a bug.

Or is there a workaround ?

Thanks
