Hi, have you already downloaded Fossify File Manager? If not, you can refer to the instructions here.
If you’ve already installed it, you can check how much storage space each folder is using. You can also send me screenshots, and I can help confirm which files or folders can be safely deleted.
If you’re not sure how to check the storage usage, you can send me the device ID separately. I’ll try to look into the relevant information and confirm which content can be removed.
