My Lenovo P770's internal memory usage is very large – although I have deleted some unimportant data/apps. This is what it looks like using DiskUsage application:

Screenshot (click for larger variant)

I noticed that theres a huge "Data" (755 MB) in my internal storage. What is this data? Is it save to delete it? How to do it (where is it's location)?

Sorry for much questions, please help me out. Thanks a lot

Note: I have used CCleaner but it doesn't help much. I think the main problem is this huge "Data".

As the screenshot shows, the "huge data" is mostly "applications" (each column represents a "detail view" of the one left to it). From the apps, most space is consumed by Facebook and Twitter. –  Izzy Jul 20 at 18:09

As you can see on the right, it contains the private data for all apps. If you want to delete these data, you can do it by uninstalling apps or by clicking "Clear data" in the apps manager.

How do i know which apps have that huge data? Thanks –  Blaze Tama Jul 20 at 9:42
    
You can see in your screenshot. Facebook is using 122.9 MiB, Twitter is using 90.4 MiB, etc. On recent Android versions, the same data are available in the apps manager: each app shows how much space it takes up, and you can sort largest-first. –  Dan Hulme Jul 20 at 9:46
    
Do you mean that "Data" is "Applications" + "System data" + "Free space" ? –  Blaze Tama Jul 20 at 9:50
    
Yes, that's how the app works. Everything to the right is inside the thing on its left. –  Dan Hulme Jul 20 at 9:57
    
Okay, i will try to do something (i think i have moved all of the apps data to the USB storage). Thanks, i will let you know what happened. –  Blaze Tama Jul 20 at 10:00
