my emulators on Android Studio were buggy so I decided to reinstall them. Prior to deleting 2 emulators (they were about 11 and 9 GBs large) I took a screenshot of available space on my file manager, and after deleting them I noticed that the available space increased by 4.8 GBs, and not ~20 GBs. I checked the trash folder and ran a disk usage analysis, but couldn't see where the emulator files went if they weren't deleted.
My OS is Pop!_OS 20.04, my Android Studio version is 2021.1.1 Patch 2 (Flatpak version) and my ADB version is 1.0.39.
Edit: The answers to this question weren't helpful, since I use Linux (and hence don't have an AppData folder) and the size of my ~/.android/avd directory is 12.5 KBs.
