How to save midi files

Hello
I would like to simply save the midi files into the telephone, not using Drive or other application.
Is it possible ?

You could try installing a File manager which might give you an option to save to internal memory. I have checked using Solid Explorer (there are others) and it shows up in the Share window as an option alongside Gmail, Drive etc. When you choose it you can specify exactly where you want to save it within the device.
There are often free versions of the file managers that might work to test with.

Thank you for your clear answer !
