Google file viewing options

When sharing a Google Doc, Sheet, etc. with others, the ending of the URL matters. Change from the "/" to the end of the URL to be...

/edit
Opens the file with your editing rights.

/copy
Forces users to "Make a Copy" of the file.

/view
Opens the file with View Only rights (unless you have editing rights to the file).

/preview
Opens the file in a preview, without the Google Editing navigation. This is a very "clean" way to view a file. This is a great way to preview a file that was shared with the "/copy" ending before making a copy of it.
