Sending one file by email is easy. Sending a whole folder feels like trying to mail a suitcase through a letterbox. The good news? You can do it. You just need the right trick. This guide shows you the best ways to send a folder by email using Gmail, Outlook, and cloud storage.
TLDR: You cannot attach a normal folder directly to most emails. First, turn it into a ZIP file, or upload it to cloud storage and send a link. For example, if Mia has a folder with 42 vacation photos that is 180 MB, Gmail will not send it as a normal attachment. The best move is to upload it to Google Drive, OneDrive, or Dropbox, then email the share link.
Why You Cannot Just Attach a Folder
Email apps like files. They do not like folders. A folder is more like a box that holds files. Email wants the items inside the box, not the box itself.
So you have two main choices:
- Compress the folder into a ZIP file.
- Upload the folder to cloud storage and share a link.
The first method is best for small folders. The second method is best for big folders. Simple.
Method 1: Turn the Folder Into a ZIP File
A ZIP file is like a suitcase for your folder. It packs everything into one neat file. It can also make the folder smaller. Sometimes a little. Sometimes a lot.
How to ZIP a Folder on Windows
- Find the folder on your computer.
- Right click the folder.
- Choose Send to.
- Click Compressed zipped folder.
- A new ZIP file will appear.
Now you can attach that ZIP file to an email.
How to ZIP a Folder on Mac
- Find the folder in Finder.
- Right click or control click the folder.
- Choose Compress.
- Your Mac creates a ZIP file.
That is it. Apple keeps it tidy.
How to Send a Folder in Gmail
Gmail does not let you attach a folder directly. But it does let you attach a ZIP file. Gmail also has a file size limit. Attachments can be up to 25 MB. If your ZIP file is bigger than that, Gmail will try to use Google Drive.
Send a ZIP Folder in Gmail
- Open Gmail.
- Click Compose.
- Write your message.
- Click the paperclip icon.
- Select your ZIP file.
- Click Send.
If the file is small, it sends like a normal attachment. Easy win.
Send a Large Folder with Google Drive
For large folders, use Google Drive. This is better for photos, videos, work projects, and design files.
- Go to Google Drive.
- Click New.
- Choose Folder upload.
- Select your folder.
- Wait for the upload to finish.
- Right click the uploaded folder.
- Click Share.
- Choose who can view it.
- Copy the link.
- Paste the link into your Gmail message.
Tip: If the person only needs to download the folder, choose Viewer. If they need to add files, choose Editor. Do not give edit access to everyone unless you enjoy chaos.
How to Send a Folder in Outlook
Outlook works in a similar way. It does not attach regular folders. You must use a ZIP file or a cloud link. Many Outlook accounts have attachment limits around 20 MB to 25 MB. Business accounts may allow more, but it depends on settings.
Send a ZIP Folder in Outlook
- Open Outlook.
- Start a new email.
- Click Attach or the paperclip icon.
- Select your ZIP file.
- Add your message.
- Click Send.
If the folder is small, this is the fastest method. If it is large, Outlook may complain. Outlook can be dramatic like that.
Send a Large Folder with OneDrive
OneDrive is Microsoft’s cloud storage. It works very well with Outlook.
- Open OneDrive.
- Click Upload.
- Choose Folder.
- Select your folder.
- Wait for the upload.
- Right click the folder.
- Select Share.
- Set the permissions.
- Copy the link.
- Paste it into your Outlook email.
You can also attach from OneDrive directly inside Outlook. Look for options like Browse cloud locations or Attach from OneDrive.
Best Cloud Storage Options
Cloud storage is the best choice when your folder is too big for email. It is also better when the files may change later. Instead of sending new attachments every time, you can update the cloud folder.
- Google Drive: Great for Gmail users. Simple sharing. Good for teams.
- OneDrive: Great for Outlook and Microsoft 365 users.
- Dropbox: Very easy for sharing folders with almost anyone.
- iCloud Drive: Useful if you live in the Apple world.
- Box: Popular for business and secure file sharing.
Cloud links are also kinder to your recipient. Nobody wants a giant email that takes forever to load. Nobody.
ZIP File or Cloud Link: Which Should You Use?
Here is the quick rule:
- Use a ZIP file if the folder is under 20 MB.
- Use a cloud link if the folder is over 25 MB.
- Use a cloud link if the folder contains videos.
- Use a cloud link if several people need access.
- Use a ZIP file if the folder is final and will not change.
Think of ZIP as a package. Think of cloud storage as a shared room. If people need to visit the room often, send a link.
How to Make the Folder Smaller
Sometimes your folder is just too chunky. It has been eating too many videos. Here are easy ways to slim it down:
- Delete duplicate files.
- Remove old drafts.
- Resize huge images.
- Convert videos to smaller formats.
- Split the folder into smaller parts.
- Compress the folder as a ZIP file.
Helpful example: A folder with 100 high quality photos might be 600 MB. If you resize the images for web use, it may drop to 80 MB or less. That is a much friendlier folder.
Do Not Forget Permissions
Cloud sharing is powerful. But permissions matter. A lot.
Before sending the link, check these settings:
- Viewer: The person can only view or download.
- Commenter: The person can leave comments.
- Editor: The person can change files.
- Anyone with the link: Anyone who has the link can access it.
- Restricted: Only invited people can access it.
For private files, use restricted access. For public handouts, “anyone with the link” may be fine. Just do not send your tax folder to the entire internet. The internet does not need that.
What If the Recipient Cannot Open the Folder?
This happens. Do not panic. Try these fixes:
- Ask if they can open ZIP files.
- Check if the download finished.
- Send a fresh cloud link.
- Make sure permissions are correct.
- Try a different browser.
- Split the folder into smaller sections.
If they are on a work computer, their company may block some downloads. In that case, a trusted cloud service may work better.
Safety Tips Before You Send
Email and cloud links can travel fast. So take a tiny safety pause before you hit send.
- Scan the folder for viruses.
- Remove personal files by mistake.
- Use a password for sensitive ZIP files.
- Send the password in a separate message.
- Double check the recipient’s email address.
- Set an expiration date for cloud links when possible.
This is boring but important. Like wearing a seatbelt. Not exciting. Very smart.
Final Answer
The easiest way to send a folder by email is to compress it into a ZIP file. This works well for small folders in Gmail and Outlook. If the folder is large, use Google Drive, OneDrive, Dropbox, or another cloud service. Upload the folder, copy the share link, and email that link instead.
So, next time someone says, “Can you email me the whole folder?” you can smile. You now know the magic trick. Zip it, link it, send it. Done.
