Connecting un-rooted Butterfly to PC as Drive letter

well, im still not giving up trying to recover my photos.

I have 5-6 different recovery programs on my PC. (once tried to recover a deleted sd-card).
Yet the PC only connects the Android device only as device, not with a drive letter. (which is required by any of the programs to recover anything.)

I've read around that in android 4+, google removed the option to connect as mass storage (with drive letter). Now i enabled developer options and tried using usb debugging, yet no drive letter. I head of the program PTPdrive and wanted to try that, but unfortunately, this program does not support Win10.

I have an unrooted, stock rom HTC butterfly with access to developer otions. I also read of something like accessing the phone over ftp, but found no real clue to my problem,
i want to connect my HTC to my PC (win 10) as drive letter to run a recovery program on it.

Anyone has a guide or tips, how to get my HTC a drive letter?

Marshmallow phones STILL NOT CONNECTING to S2

Samsung released a Marshmallow (Android 6.0/M update to the Gear app, the Gear Plugin, and the Samsung Accessory Service apps on October 12. They then released updates again on October 15 and 16.

None of these three updates allow the S2 to stay connected via Bluetooth to your Marshmallow phone. Phone will connect once, and then fail to reconnect UNLESS you do a "Light" or "Factory" reset. Of course you lose some or all of your data and settings. And then if your S2 goes out of range of Phone, reset time again.

Just wanting folks to be aware. Suggest you leave a comment in Google Play for all three apps, but who knows if Samsung even reads those comments. At this point I don't even know if the people at Samsung who need to know about this, are even aware of issue.
