Multiple Folders in Google Drive
You can have a file in Google Drive “live” in multiple folders. The paradigm shift, of course, is there is no such thing as folders. Folders are what are in filing cabinets. A virtual folder is actually a label. When you put a file in Google Drive into a Folder it is labeled with that folder name and removed from the view of My Drive. When you put a file in multiple folders, the file is not in multiple folders it really just has multiple labels.
This will give you the option to add the file to multiple folders.
Also, if you go to docs.google.com/create or slides.google.com/create or sheets.google.com/create a new file is created quickly, but it also is in My Drive, not a specific folder. Click the folder icon next to the file name or use the File menu to organize the document into a folder. Notice the blue button says “Move here.” This places the document into a folder (labels it) and removes it from the My Drive view.
If you want to create a file in a specific folder, first go to Google Drive and open the folder. Then click the New button. This will create that file in that folder.
In Google Drive if you right click on a file and choose the “Move to…” icon (which is also in the toolbar) this will MOVE the file OUT of the current folder (which might be My Drive) and into the folder you designate.
