# Why is my Pictures folder so big?

Almost always because of the **Photos Library** — your whole photo and video collection lives in that one item inside Pictures. Other libraries live there too, such as **Photo Booth**, plus any images or exports you've saved directly.

Don't open the library and delete things inside it; manage photos within the Photos app. To shrink it, delete what you don't need (then empty Recently Deleted), or move the library to an external drive. See [where the Photos library is stored](https://storagestudio.us/faq/mac-storage-basics/where-is-the-photos-library-stored-on-a-mac) and [why the library is bigger than your photos](https://storagestudio.us/faq/mac-storage-basics/why-is-my-photos-library-bigger-than-my-photos).
