Answer:
The importance of moving copying and deleting file on folders is that first of all it saves you more storage as you delete some files, and also you can organize your folders well. for example suppose you have documents folder but in that folder there is a image file stored on it, deleting it or moving it on the right folder will organize the documents folder so that only documents is stored in that certain folder and later on if you are finding a document file you won't get confused on where you have stored the files for documents only.
