BlackBerry software needs to make their file App slightly more user friend friendly . you should be able to file an attachment to a file folder very easily . Old bb10 was the simple eg save or move File etc

That's not BB's file manager - it's TCL's. But there are plenty of better file managers available on Android (try Solid Explorer or the ASUS file manager), so there's little point in investing money to make another one.
