How to open files for mobile applications, such as where are the files corresponding to external cache?

[tthbaltazar]

In later android versions external cache can only be viewed using the OS built in file manager.

It's on the SD card: Android/{application package ID}/cache.

Yes, if you want to access app's internal files, you can not use this app.
You can however view the apps themselfes, and see how much space their cache and so on takes.
