I have a HTC Desire 510, Android version 4.4.3, HTC Sence version 6.0 Software number 1.51.401.7 HTC SDK API level 6.25
When I go to storage I see:
- Apps 3.56GB
- Music 110MB
- Photos & videos 60.82MB
- Other 3.88GB
- Available 400MB
I want to make more internal memory available. When Clicking on more space (or selecting apps from the settings menu) I see:
- 7.59GB / 8.00GB
- Apps 1,21 GB
- Gallery 47.74MB
- Miscellaneous: 107MB
About 6.5 GB of memory use is not listed!
Does any one have an idea what that can be and how I can free it?

I understand that the system also uses some internal storage. The frustrating part is that the "missing" memory used to be less.
It seem something beyond my control is eating away internal storage. I've followed the instructions at https://www.xda-developers.com/install-adb-windows-macos-linux to install adb and get the following result:
Filesystem Size Used Free Blksize
/dev 432M 152K 432M 4096
/sys/fs/cgroup 432M 0K 432M 4096
/sys/fs/cgroup/memory: Permission denied
/mnt/asec 432M 0K 432M 4096
/mnt/obb 432M 0K 432M 4096
/system 2479M 1611M 868M 4096
/data 4091M 3646M 444M 4096
/cache 309M 256K 309M 4096
/devlog 15M 9M 6M 4096
/fataldevlog 15M 8M 7M 4096
I'm fine with a system needing 2GB for other stuff. What amazes me is the 3.5GB for data when I only have a few small app's installed. When I want to do an ls for /data I get permission denied.
I've used SD Maid Storage analyzer. It tells me /storage/emulated/0 has 3.6GB used / 3.9 GB capacity. Clicking on it gives me only 534MB used. More than 3GB is gone! I really want to have it back because I can hardly update any app let alone install new ones.
With regard to the .data directory: There is one other directory in it with a dozen of files with sizes in KB's (not even in MB's)
