Wirelessly sync music folder to microSD card I am looking for a way to sync, wirelessly or over a cloud service, a (music) folder from my computer to the microSD card on my rooted phone.
I've been trying this on Android MM with Titanium Media Sync app but it seems MM restricts the app from writing on the SD-card "Error. Failed to create local folder." 
I recall to be able to do so on another phone with CynogenMod...
Probably the feature that TMS is missing is superuser permissiom request. FolderSync as noted in the comments does asks for superuser priviledges and can perform two way syncing!
