On older Windows® (including Windows 8.1®) I could browse Bluetooth devices (using the same hardware as today) so I could choose where I was sending files on my phone. I could also browse the computer from my phone (I always used my ᴘᴄ as my phone lack a true keyboard).

Since Windows 10, the share tab does no longer exists in the Window above (only 3 tabs remain).
My phone has 2 memory, and the first (the default) is only 2Mb large (the second is micro sd). So If I send a file without browsing the phone (in which directory I put it), then the file is rejected if it is larger than the memory used for storing sms (the 2Mb memory).
Samsung confirmed there’s no way to change the default memory for receiving Bluetooth files.
Since the reorganization of the user interface on Windows® 10, I’m unable to find how I can browse my phone over Bluetooth (it has only Bluetooth connectivity).
So I’m in the situation I can send only tiny files to my old java phone, as I only found how to pair the device or send files without browsing it.

As far as I can tell, Microsoft removed the ability to natively mount your phone's file system in Windows 10 so you can browse it.
Previous versions of Windows had this ability, but it's gone now and most posts I see out there say you need a third party program to do it.
Someone alleged that this is because of some interface problem Microsoft was having, but the explanation was vague and seemed implausible to me. Essentially, the files weren't displaying cleanly. Again, that makes no sense considering the modular nature of the Windows interface.
