That's my problem: I use, happily, link2sd and after installing a lot of apps I got my internal memory full again.
Now I'd like to delete apps but I have no clues on how internal space they use since I've moved them with link2sd...
Any apps/hints?
Use Disk Usage app. It draws nice graphical diagram with directories proportional to their size. There's a dedicated lookup option for apps too.
Link2SD comes with awesome filter settings and sort size.
So in filter settings choose 'Internal memory' and in Sort choose 'By data size'.
This way link2sd will show you all the programs that are in internal memory in descending order of their data size.
