For public convenience WhatsApp is making it easier to clear up storage right from the app.
WhatsApp already had basic functionality for clearing stored media, but now you get full-fledged data management. If you head to WhatsApp >> Settings >> Storage and Data >> Manage Storage, you’ll be greeted with a new interface that categorizes items by size, and allows you to preview files before deleting them.
You can then select multiple items to delete, while maintaining the files you want to keep.
The new feature will also divide media into two categories: files larger than 5MB, and files that have been “forwarded many times.” Furthermore, WhatsApp will also now display a warning when your phone is running low on storage, prompting you to delete some media files.
