Android Marshmallow (rooted): How to read / write any file

I recently updated to Marshmallow (Cyanogmod CM13) and, due to the new permissions regime, a lot of my apps no longer work.

Note that these apps are not on the Play Store and are for my own personal use. So security is not much of a problem - I'll let my apps access whatever I want them to access.

The problem is how to achieve that.

I've tried doing a "su -c chmod" to modify the permissions but that does not work.

Other apps (eg Jota+) can browse to and write to a file. How do they do that? (Yes, I've tried searching but have not hit on the right search terms - if the answer is "out there".)

EDIT: The sdcard has been "adopted" and all relevant files transferred to it.

Edit platform.xml at /system/etc/permissions/platform.xml.

Find these lines

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
    <group gid="sdcard_r" />
    <group gid="sdcard_rw" />
</permission>

Change to

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
    <group gid="sdcard_r" />
    <group gid="sdcard_rw" />
    <group gid="media_rw" />
</permission>

Now you'll be able to write to sdcard like in earlier Android versions.
