Create shared folder on sdcard Is there any way to create a directory on an external sdcard that has read/write access for multiple apps. For example I want to us synththing or rsync under termux be able to sync this directory to my file server. I also want to be able to download music from a browser or other app and add it to the directory, which would then be synced with the file server. 

I am using an Android k7 with android 5.1.1

My phone is not rooted and I would rather not root it unless I have to.
Run

termux-setup-storage


And create anything you want in ~/storage/shared (which is a symlink to /sdcard.
