Misc. files that I can't find but that take up about a half of available storage I have the following problem: about half of my phone storage is filled by files that grouped as Misc in Android Storage app. The problem is that I can't find these files. If I open the Misc. category there is no files displayed that can fill up that much space (the same thing goes for ES File Explorer SD card analyst). 

So the question is how I can find this files.
(I have a suspicion that it's some kind of remnants from BOINC application,  but this is not helping me in any way)

Here should've been another image to illustrate the situation with analysis from ES File Explorer SD card analyst, but I don't have enough karma for that.
You can try DiskUsage app (free), it shows detailed information about memory usage and also gives you option to:


Scan internal or external SD and graphically display space occupied by directories/ sub directories
Choose files / sub directories / directories for deletion
Re-Scan after deletion so that you can free up desired storage space
