During first time synchronization, Shared Folder Sync will makes a full sync of the select ed s hared folder(s).
Afterwards, only changed files will be synced from the client to t he server.
All files that have been removed from the client will also be removed fr om the server.
The access privilege to folders synced to the server will be set as default, which means not s pecified.
During the syncing process, the client will copy the selected shared fol der s to the server. However, if a folder with
the same name already exists on the server, that folder will be renamed as " s hared_folder_name 1" to prevent its
data from being overwritten.
Task name must be of 1 to 32 Unicode characters and must not contain the followi ng characters:
! " # $ % & ' ( ) * + , / : ; <= > ? @ [ ] \ ^ ` { } | ~
If you sync shared folders from ext4 to ext3 file system, you may encounter er rors when a folder has over 32,000
files in a single directory.
If the shared folders on the server have been synced with another cli ent, Shared Folder Sync will perform a full
sync for the task.
