How to change the ringtone of IPHONE SMS? In which folder?

Open itunes, enter the music list, and find the song you want to ring, such as Direct Answer. Double-click Play, and you can see that the playing time is displayed at the top of itunes, and the recording time is the climax of the ringtone, for example, 1: 05- 1: 35. The ringtone file size of iphone cannot exceed 40 seconds.

Step two:

Right-click the name of the song that you want to ring, enter "Show Introduction", enter "Options" in the top label menu bar, enter the start time and stop time respectively, and then confirm.

Step 3: Return to the itunes music list interface, right-click the song again, and select "Convert selected content to AAC" in the menu. After that, you will see an audio file with the same name in the song list, but the playing time is much shorter than the original file. This is the matrix of the ringtone file we want:

Right-click the file, select "Display in windows Explorer" from the menu, and change the file suffix from "m4a" to "m4r" in the pop-up window.

A friend said that you didn't see the changed ringtone because the computer you used didn't set itunes as the default player to play the .m4r format file, so the ringtone file was not opened through itunes, so it won't be added to the ringtone database in itunes.

Put the ringtone file with the suffix changed into a folder, and then add the ringtone file to the itunes repository through the File-Add Folder to Repository function in the itunes menu, just like importing music files, or right-click the original double-click operation and select itunes to open the file.

The last step: synchronize iphone with itunes, select all the ringtones or select the ringtones to be synchronized separately, and then click "Sync" in the lower right corner to get it.
