Room tidying and cleaning

For the last week been busy with tidying up my study room. Then i realize that i have stacks of stacks of notes and also articles and literature, getting all of it together and also rearranging it took me about 3 days. After getting everything together and place it into my shelf, i realize that I need to get a new cabinet because the current one is already full and there is still some stuff that is not being place into the shelf. But even if a get 1 new one my study room would not manage to fit it in, every conner of the room have been occupied. So it looks like I need to look for a new 'Base' to keep all my stuff and it should have a bigger space.

My Shelf with all my books and notes(looking at it make me feel stress)

All bags and files
