Sharing files from Delta Drive and My Drive

You can share any file or folder in Delta Drive or My Drive with the people you name — and only them. Each person gets an email, opens the share in a browser with a one-time code (no account, no password), and can do only what you allowed, until the date you chose.

Making a share

1. Select the file or folder and choose Share in the bottom bar, or right-click it and choose Share… (shortcut ⇧⌘S).

2. Optionally give it a name under Name this share (optional).

3. Under Who can open it, type the email addresses, separated by commas. Only these addresses can open it.

4. Under What they can do, pick a level:

   Level	What it allows
   Read	Open and download. Nothing they do can change anything.
   Comment	Open, download, and leave comments on the files. Still can't change them.
   Read / Write	Add, rename, move and bin things inside what you shared — and comment.
   Reshare	Everything Read / Write allows, plus passing it on to other people.

5. Under Stops working after, choose 1 day, 7 days, 30 days or 90 days.

6. Choose Create share. Storage Studio emails everyone on it. The link only works for them — it's useless to anyone else.

The levels on offer come from our servers, so the list in your app always matches what a share actually allows. A disposable email address is refused when you create the share.

Changing what one person can do

On an existing share, each person has their own row under Permissions, set to Same as the share by default. You can give one person more or less than the rest. Owner — full control of what you shared, as if it were theirs — can only be given to someone who has already opened the share.

Who opened it, and withdrawing it

• The Shared screen in the sidebar lists everything you've shared. Copy link copies a share's address; Withdraw stops it working straight away. Turn on Show expired and withdrawn to see past shares.
• In the Share sheet's list, Activity shows what has happened on a share, and where it was opened from by country and city — never the visitor's own address.
• The Recent screen, set to Opened, shows when somebody you shared with last opened or downloaded a file.

Items inside a live share carry a small two-person mark, so you can see at a glance what others can open — see What the Delta Drive badges mean.

Things shared with you

When someone shares with your address, it appears in your drive's Shared folder on the web, in a folder named after the person who shared it, alongside anything you keep there yourself.

Shares belong to one drive

A share remembers the drive it was made on. If you switch that drive off, disconnect it, or your My Drive is paused, the people you shared with see "This share isn't available right now" until it is back. They never see files from a different drive.
