Blot, this beautiful closed system does not pour ringtone mp3, put in the ringtones folder with desktop windows via FTP.
P.S. But how else to move the files from Windows to Windows only FTP, it is logical, no cable. However, Windows does not see another cable.

It is over the cable and it is necessary to throw ringtones into the ringtone folder, they will no longer see any other way, but they will lie there but will not be dug, so only on the cable ...

* ansenin, * Ivanivanych255, * lctford,
Why do you create problems? The store has an application from Microsoft, called the "Melody Creator".
You open the application, specify a music file, cut the desired fragment (when the melody is loaded, you can redone to the right position), save (saved to the ringtones folder). The saved melody appears in the ringtone list to call and in the Melody list for SMS.

* Helgi2002, Sometimes it is easier to throw files. Especially if it is 20 or even less than a second file. You can also through Pocket File Manager. There is a item to make a ringtone or something like this

It is for nothing, it's easier to throw it on the cable than installing something ..., I think this is extra trash ...

Yes, they will lie there but will not twist, so only on the cable ...

Thanks for the advice. And then, from the clouds through the conductor, I threw the ringtones into the folder, they lie there but do not twist.



Rep: (430)
* lctford, Here you are in vain. The application is very useful, downloaded the song and on the smartphone itself chose the desired fragment and immediately put on a call, without PC and unnecessary gestures.

I repeat the question of a friend above, weighs gig in time, how to remove?



Rep: (430)
* iJleoH, Clear temporary files and more than once, clean the browsers all that is. Clear the same applications where everything is available through their menu. For example, the PDF file cache in Adobe Reader. You can still try the WinTools program

Good day to all. There is such a problem: Updated to Win 10, periodically when calling the subscriber GAS screen, turned on by pressing the power button, then began to go out with each call, tired. I rolled back to 8.1 (there were no such glitches on it), the problem was left. Maybe someone came across this, tell me what to do. Thank you.

The problem is most likely with the approximation sensor. It can be sealed with a film / glass, may just be stupid.
