File System tech note
Chartarium can connect to any Local, iCloud, shared computer and remote server Working Folder which can be accessible through Finder (Mac) or File (iOS).
The reason of the Apple' decisions to make FTP protocol access to remote servers just read-only through Finder (for Mac OS X), orients the access to remote servers using the samba protocol (of kind smb://). File (iOS devices) doesn't allows any ftp connection.
As any other else app interacting with remote servers accessible through Finder or File, through the samba protocol, we noticed a performance quite embarrassing.
We experienced, anyway, excellent performances in terms of speed of connection with iCloud located Working Folders and obviously with local ones.
