How do i empty the trash can on my optimus zone 2?

i just want to know how i can access the the trash can so i can empty it and also retrieve anything i accidentally threw away.

Hello. Welcome to Android Central.

I don't think it's like Windows recycle bin.
There's a hole in the bottom.

There may be ways to retrieve something if it has not been overwritten, but it's gone. (Unless I'm mistaken)

Recovering Deleted Files

When Android deletes a file, it doesn't just move it to a hidden folder. (That's what Windows does.) It actually marks the space that the file is sitting on as being unused. The data is still there (there's always data, even on a new, empty hard drive), but it's just about all marked as unused. When Android deletes a file it sets that space back as unused. If nothing gets stored in that space, the file can be recovered.

And there's a hole in the bucket, Dear Liza. (Name that singer.)
