iOS operating system has a number of limitations which, in their turn, bring some limitations to Sync. This article contains details on how Sync works due to these limitations.
- Files are copied when opening them in other apps.
When you choose "Open In..." to open a file in another app, the file is actually copied to other app. As a result, that app works on a copy of the file and all changes you make are not reflected in the file which is stored in Sync. To sync changes to other peers you'll need to send back the modified file to Sync. Click here to see an example.
- Deleted files are not deleted from other peers.
When you delete a file from iOS it actually simply "un-syncs" it from iOS. It will not send command "Delete this file on all peers as user deleted it".
- Media Library is not accessible.
Media Library on your iOS device can only be accessed via iTunes. So, Sync cannot save your music and videos to Media Library. Though, Sync can send them to other apps.
- Sync cannot "Open In..." many files.
So you can transfer files to other apps only one-by-one.
- Sync cannot access files of other applications.
As a result, you cannot sync files which are stored in other applications unless you transfer them to Sync explicitly using "Open In..." mechanism from other apps.
- Not working in the background.
Sync cannot transfer data in the background. It needs to be open to transfer data. So, if you are using backup for Camera Roll, you need to open Sync to let it actually transfer your pics.
