Where is android /storage/emulated/0

[Andrew Beckett]

The default location for Apache K9mail attachments is:

Settings > Account settings > Storage > Storage location =
regular internal storage

Settings > Global Settings > Miscellaneous > Save attachments to =
/storage/emulated/0

One of many ways to address regular internal storage is
"/storage/emulated/0"

I guess that means that the "0" must be the "Phone" mount point which
shows up when I plug in an Android device onto a PC by USB cable.

So, for example, the "Phone/Download" folder at the top level of that
mount point must really be at "/storage/emulated/0/Download", with the "0"
taking the place of the "Phone" mount point.

Likewise with the digital camera directory "Phone/DCIM", which would be
at "/storage/emulated/0/DCIM" and the "Phone/Pictures/Screenshots"
directory at "/storage/emulated/0/Pictures/Screenshots".
