Help with folders

Haha I promise this'll be my last question for awhile. You know when you delete a folder in your finder and there's a space where the folder would be if it wasn't deleted? Is their a way to make the next folder take it's place so everything is spaced evenly? I would prefer not to drag because it doesn't align its self perfectly and takes a while to drag many folders. Also, will downloading, and reinstalling things many times harm the computer/drive in any way? Thanks.

Go to view/arrange by/make your choice.

When this happens to me I just press Command + A to select all files in the window and then go to Finder Menu ~> View ~> and choose either Clean Up/Arrange By: ... 9 times out of 10 it cleans things up how I like it to look.
