How to send a whole folder from a Mac to someone else

If the other person is nearby with a Mac, iPhone or iPad, AirDrop the folder as it is: it arrives whole, subfolders and all. If it has to travel by email or a chat app, right-click it, choose Compress, and send the zip, because most of those take files but not folders. For a big folder, or one you will keep changing, put it in iCloud Drive and share a link instead of sending a copy.

Pick the route by where the folder is going

A folder is a container, not a file, and that one fact decides most of this. Some routes carry containers and some do not.

• AirDrop carries a folder intact between Apple devices that are close to each other. There is no account to set up and no internet connection involved.
• Email and chat apps carry files. A folder has to become one file first, which is what Compress does.
• A shared iCloud Drive folder does not send anything. It gives the other person access to the folder where it lives, so your later changes reach them too.

The useful question is less “how big is it” and more “does the other person need a copy of how it looks today, or ongoing access to it”.

AirDrop: the folder as it is

1. Select the folder in Finder.
2. Right-click it, choose Share…, then choose AirDrop. Or click AirDrop in the Finder sidebar (Go > AirDrop, Shift-Command-R) and drag the folder onto the other person’s picture.
3. Pick the person or device. They accept on their end.

On a Mac, the folder lands in Downloads with everything inside it. Where AirDropped files go on a Mac covers the receiving side.

If the other device never appears, check its AirDrop setting. On a Mac, the AirDrop window shows “Allow me to be discovered by:” with choices including Contacts Only and Everyone. Contacts Only works only when you are in their contacts with the email address or phone number your Apple Account uses, so switching the receiver to Everyone for the moment is the quick fix. Both devices need Wi-Fi and Bluetooth on, and both need to stay awake and near each other until the transfer finishes. A folder of several gigabytes can take a while, and closing a laptop lid halfway through stops it.

An iPhone or iPad handles an incoming folder according to its iOS version and what is inside. If it does not land the way you expected, send a zip instead; the Files app can expand a zip with a tap.

AirDrop works only between Apple devices. A Windows PC or an Android phone needs one of the other two routes.

Compress it for email or a chat app

1. Right-click the folder in Finder.
2. Choose Compress, which shows the folder’s name in quotes, such as Compress “Site photos”.
3. A file called Site photos.zip appears beside the folder. The folder itself is not changed.
4. Attach the zip to the email or drop it into the chat.

The person on the other end double-clicks the zip and gets the folder back with its structure intact. A Windows PC opens zip files without extra software.

Three things to know before you send. The zip will not be much smaller if the folder is mostly photos, video or PDFs, because those are already compressed; zipping is about making one file, not saving space. macOS tucks a few housekeeping files into archives it makes, and they can show up as a folder called __MACOSX on other systems; they are harmless. And check the size before you attach anything: select the zip, press Command-I, and read the Size line in the Get Info window.

If the things you want to send are scattered across several folders rather than sitting in one, how to zip files from different folders into one archive covers gathering them, including a Terminal route that moves nothing.

Share a link from iCloud Drive

A link suits a folder that is large, that will change after you send it, or that several people need. The folder stays in your iCloud Drive and they get access to it. The share sheet’s own description puts it plainly: add people to the folder and everyone will see the latest changes.

1. Put the folder in iCloud Drive, in the Finder sidebar. Dragging it there from elsewhere on your Mac moves it; hold Option as you drop if you want to leave the original where it is and put a copy in iCloud Drive.
2. Wait for it to finish uploading. Finder shows upload progress beside items that are still on their way.
3. Right-click the folder and choose Share…
4. In the share sheet, find the pop-up menu that switches between Collaborate and Send Copy, and choose Collaborate. Send Copy sends a one-off copy, which puts you back on the email route.
5. Click Share Options to set who can access it (Only people you invite, or Anyone with the link) and the permission (Can make changes, or View only).
6. Choose how to deliver the invitation: Mail, Messages, or Copy Link to paste anywhere.

Those are the words macOS 15 Sequoia uses. Older versions offer the same choices with different wording or in slightly different places, so look for Collaborate and Share Options rather than an exact layout.

A few honest caveats. The folder counts against your iCloud storage. The people you invite may be asked to sign in with an Apple Account before they can open it. And because it is one shared folder rather than a copy, deleting it from your iCloud Drive takes it away from them too. To change or stop sharing later, right-click the folder and look for Manage Shared Folder.

Size limits, in general terms

There is no single number, because each route and each service sets its own.

• Email. Many providers cap a message somewhere around 20 to 25 MB. Attachments also grow by roughly a third when they are encoded for sending, so a 20 MB zip can already be too big. Mail on a Mac can hand a large attachment to Mail Drop, which delivers it through iCloud as a download link; how to attach a whole folder to an email on a Mac walks through that.
• Chat apps. Each sets its own upload limit, and free plans often allow less than paid ones. The app tells you when a file is over.
• AirDrop. There is no attachment-style cap to plan around. The practical limits are time, battery, and both devices staying awake.
• iCloud Drive. The space left in your iCloud storage plan is the limit you are most likely to meet.

Where a shelf fits

None of these routes needs extra software. What slows people down is the step in the middle: the zip is in a Finder window, the conversation is in another app, and the two are rarely on screen together.

Ledge gives that step somewhere to wait. Drag the zip up to the notch at the top of a MacBook screen, or to the top center of the screen on a Mac without a notch, and let go; it lands on a shelf that drops from the notch. Then open the chat, find the right conversation, press Option-Space or click the notch, and drag the zip off the shelf into it. A chat app uploads the file. Dropped on a Finder folder instead, the file itself moves there.

Be clear about what it does not do. Ledge does not send anything to anyone and does not carry files between devices: AirDrop, Mail, a chat app or iCloud Drive does the sending. It has no account and no cloud, so nothing leaves the Mac until you hand it to one of those.

Questions

Can I AirDrop a folder to a Windows PC?

No. AirDrop works only between Apple devices. Compress the folder and send the zip by email or a chat app, or share an iCloud Drive link the other person can open in a browser.

Why will my chat app not take the folder?

Upload fields expect files, and a folder is a container with no single file to send. Compress it and drop the zip in instead.

If I change the folder after sending it, does the other person see the change?

Only with a shared iCloud Drive folder set to Collaborate. AirDrop and a zip are copies of the folder as it was at that moment, and later edits stay with you.
