If you're looking for downloads on Android (https://devicefixes.com/blog/where-are-my-downloads-on-android/), you will find most of the files in the Downloads folder, which can be accessed from the Files app or built-in file manager on your device. Documents, images, videos, PDFs and other files that are downloaded from websites, emails, or apps usually appear in this folder. If you can't find the file in the downloads folder, looking in the app where it was downloaded from, can also help, as some applications store files in their own folders. Another easy method for finding particular downloads is to use the search function in your file manager. Frequently sort and remove the files that are not needed, it will be easier to locate important content and make room for the storage.
