To make two columns in Google Docs, select the text (or nothing, for the whole document), click Format → Columns, and choose the two-column option. Use Insert → Break → Column break to push text into the next column. For two independent columns, such as a resume, insert a 2×1 table and hide its borders.
To download a large Google Drive file with curl or wget, share it as Anyone with the link, copy its file ID, and request https://drive.usercontent.google.com/download?id=FILE_ID&export=download&confirm=t. The confirm=t parameter skips the virus-scan warning page. Private files need the Drive API with an OAuth access token.
To find a Google Doc's parent folder, click the Move icon (a folder with an arrow) next to the document title. The dialog shows the current location; click the open-in-new-window arrow beside it to open that folder in Google Drive. You can also use File → Details, which lists the document's Location.
To lock a Google Doc, open Google Drive, right-click the file, choose File information → Lock, and confirm. A locked Doc can't be edited, commented on or suggested on until someone unlocks it. Anyone with edit access can unlock it, so locking prevents accidents rather than enforcing security.
