You can make copies of files, for instance if you want an easy to find backup (rather than having to wade through Revision history) or if you want two forms that are very similar. For most purposes, you can use copy and paste, but there is an easier way, and forms cannot be copied using copy and paste. Google has a built in copy function that copies an entire file, forms included.
- For documents, go to File -> "Save as new copy"
- For spreadsheets or forms, go to File -> "Create a copy" (Note: Copies of forms like this show up with the spreadsheet icon in your main Google Docs page, but the form is there in the copy also, with a new link.)
- For presentations, go to File -> "New copy of presentation"
Note: Revision history is not copied with the file.
