I want to copy a file in my Google Drive using the web interface. Adding it to another folder seems to create a hard link rather than a file that can be changed independently of the original. There doesn't appear to be an action with a name like "copy," "duplicate," or "clone."
Yes. While editing the document open the File menu and select Make a copy...
You can optionally copy the collaborators from the original document. Comments are not copied.
It appears Google have made this very difficult, I guess to stop the accidental creation of various versions of documents.
If the file is a Google format, you can open it and select File → Make a copy to duplicate it.
If it isn't, the only work around I've seen within the web interface is this cumbersome solution. (Only for files smaller than 25Mb.)
Right click file name in Google Drive > Share > Email as Attachment to yourself > open file in Email > Rename > save to Drive
Doesn't work for folders, but you can Right-Click each file and "Make a copy", which you can then drag-n-drop to your new destination. Although lots of clicking, I'm using this method.
If you select a file then hold control (CTRL) key and click "move to" google drive will create a hard-link of sort so the file will appear in both locations but if delete from either location it will delete the file i think.
Open Google Drive in the browser and select one or more files or folders.
You can use the Ctrl key on Windows, or cmd key on Mac, to select non-consecutive files and folders. Now press Shift+Z and you'll see an Add to Folder pop-up.
Select the folder where you wish to place the selected files and click OK.
There is a workaround to this. If you have Microsoft SkyDrive, put your Google sync folder inside the SkyDrive and do your copying from within SkyDrive.
