Because the space occupied by application manuscripts and data will increase with the increase of use time, QQ's own cleaning function can't clear this part of cache files for the time being. So deleting the APP means deleting all the manuscript data, but I suggest you back up the important things.
Method 2:
Open "Settings" in "Me" in QQ and enter the "General" interface, and you can see "Clean up QQ storage space". Select click, and after the information is loaded, you can see what junk information is, and you can choose to delete it or delete it all. Select and click "Delete" in the lower right corner, so you can choose to clean up what you want and clean it up.
