There are a few ways to delete files on Android. The first way is to use the File Manager. To open the File Manager, open the Settings app and select “File manager.” From the File Manager, select “Delete.” To delete a file, drag it onto the “delete” icon in the top left corner of the File Manager. If you want to rename a file, click on its name and then drag it onto the “rename” icon in the top left corner of the File Manager.
