The default file manager in Windows phone does not allow you to transfer files via file manager. XDA Forum member MOHSEN-UNIQUE has come up with Unique File Manager, the very first file manager which supports Bluetooth file transfer. The unique file manager is as good as any other file manager in your app list, so it is definitely worth trying out. You will need a full unlocked ROM to install .
Unique File Manager lets you extract zip files, manage files and folders and read text files, install xap files, process script file etc. So here is how to install Unique File Manager.
1. Download DFT Bluetooth Driver from here and install it.
2. Download Unique File Manager xap file from the bottom of this thread and Install it.
It’s as easy as that. You can now transfer files using Bluetooth from WP file manager.
