Delete an Album in Gallery auf Xiaomi
The Gallery app on Xiaomi phones sorts photos and videos into albums. Some albums are created automatically, such as Camera or Screenshots, while others are custom folders you made yourself or that came from apps like WhatsApp.
Deleting an album removes the album entry and every file stored inside it, not just the folder shell. If a photo only exists in that one album, it is gone once you confirm the deletion. If the same photo also appears in another album or was backed up separately, only that copy inside the deleted album disappears.
To remove an album, open Tap on Gallery ➔ Tap on Albums ➔ Tap and hold an Album ➔ Tap on Delete ➔ Tap on OK. The album and its contents move to the device trash for a limited time before permanent removal, depending on how your Gallery app handles recently deleted items.
If you only want to declutter without losing media, move the photos to another album first, then delete the now-empty original. This is the safer option for albums tied to messaging apps or downloads where files are not stored anywhere else on the phone.
