Garbage cleaning for Instagram

Posting a video or photo to Instagram will make a copy of the same thing.
If you post many times, this will accumulate more and more,
From a general photo gallery or other app, it looks like there are two of the same thing, and you can't tell which is the master.
This app deletes all the copy files that have been created automatically.
* Unconditionally delete everything under Movies \ Instagram and Pictures \ Instagram in the built-in memory, so please use at your own risk.
