Dropbox Storage Full? How to Free Up Space
Founder and CEO, The Drive AI
TL;DR: First check which "full" you have. If dropbox.com says your account is full, the fix is to remove files, leave shared folders you don't need, or upgrade. If your computer's disk is full because of Dropbox, make files online-only: that frees the disk but not your Dropbox quota. Shared folders you've joined and Dropbox Backup both count against your storage, which is why an account can look empty and still be full.
Disclosure: The Drive AI publishes this guide and makes a file agent that can measure and clean up a connected Dropbox. The Dropbox features below are described from Dropbox's own help pages as of October 2026.
Why is my Dropbox storage full?
Your Dropbox storage is full because the files you own, the shared folders you've joined, and any Dropbox Backup or Replay data add up to your plan's limit. Dropbox Basic starts at 2 GB (Dropbox Help). Shared folders count against every member's quota, so a folder someone else shared can fill your account even if you uploaded nothing.
Dropbox's storage bar splits your usage into five parts, as of October 2026: regular files (what you own and haven't shared), shared files (shared files and folders you've joined), unused space, Backup and Replay. (Dropbox Help, check storage space) Look at that bar before deleting anything.
Is it your Dropbox account or your computer that is full?
They are two problems with two fixes, and the message tells you which. (Dropbox Help, storage space limit)
| Message | What is full | What fixes it |
|---|---|---|
| "Your files have exceeded the storage on this plan" | Your Dropbox account | Remove files, leave shared folders, or upgrade |
| "Your account is full and has stopped syncing" | Your Dropbox account | Same as above |
| "You are running out of disk space" (Windows) | Your computer's drive | Online-only files or selective sync |
| "Your startup disk is almost full" (Mac) | Your computer's drive | Online-only files or selective sync |
The confusion comes from the word "free up space". Making a file online-only removes its copy from your computer, but Dropbox is explicit that "online-only files take up storage space on dropbox.com". (Dropbox Help, online-only files) So online-only fixes a full disk and does nothing for a full account.
Why is my Dropbox storage full but there are no files?
Usually because the space is used by something outside your own file list: shared folders you've joined, Dropbox Backup, or Replay. Each has its own segment in the storage bar. Deleted files are not the cause.
- Shared folders. "The size of a shared folder will be counted against the quota of every member of that folder," unless everyone is on the same Dropbox Standard, Advanced or Enterprise team or the same Family plan, where it counts once against the shared quota. (Dropbox Help, shared folders and storage) A 1.8 GB folder a colleague shared with you uses 1.8 GB of your 2 GB. Shared folders you haven't joined don't count.
- Backup and Replay. A computer or drive backed up with Dropbox Backup, or video in Dropbox Replay, shows under its own segment, not in your files.
- Deleted files. Not the cause. Dropbox's delete page says: "Deleted files don't count against your storage quota, so permanently deleting them won't free up space." (Dropbox Help, delete files)
So emptying Deleted files frees nothing and only removes your chance to restore them.
How do you see what is taking up space in Dropbox?
Open the storage bar for the totals, then look for the largest files. On a Mac, the desktop app sorts local files by size. Team admins get a Manage storage tool on dropbox.com that ranks folders and files by size. Dropbox's help pages describe no equivalent for personal accounts.
Step 1: Check the storage bar
On Basic, Plus, Professional or Essentials: log in to dropbox.com, click your avatar in the upper-right corner, click Manage account, and check the storage bar under Subscriptions. On Standard, Business, Advanced and similar team plans: click your avatar in the bottom-left corner, then Settings, then Plan. (Dropbox Help, check storage space)
Step 2: Find the large files
On a Mac, the desktop app has a Manage hard drive space tool: click the Dropbox icon in the menu bar, open the account menu, click Sync & storage, then Manage hard drive space under "Available offline files". It lets you "view and sort files by size and the date they were last modified." (Dropbox Help, online-only files) Its button makes files online-only, which helps your disk, not your quota. Use it to spot what is large, then delete what you no longer need on dropbox.com.
Step 3: For team admins, use Manage storage
On Standard, Business, Advanced, Business Plus and Enterprise, admins can click the more options icon next to a folder, then More, then Manage storage. It shows how much each file and folder uses and sorts by Largest or Last Activity. (Dropbox Help, manage team storage)
For a personal account with many folders, see what is taking up space in Dropbox shows how to get the biggest folders and files in one request.
What happens when your Dropbox storage is full?
Syncing stops. Dropbox lists three effects of a full account: file syncing stops, "You can't upload new files", and "Some sharing, moving, and preview features may be limited." Syncing resumes once the account is no longer full. (Dropbox Help, storage space limit)
For some Dropbox Basic accounts that stay over the limit, Dropbox says it may delete files you own, after notifying you "through multiple emails in advance", starting with "your least recently modified files first" until the account is back under the limit. Shared folders you don't own are removed from your account without deleting their contents. Those files can be restored from Deleted files for 30 days once you have enough space. (Dropbox Help, exceeding storage on Basic)
The same page warns that online-only placeholders on your computer, and files marked for offline use in the mobile app, may be deleted too. So don't leave a full Basic account for later: download anything you need to keep first.
How do you free up space on Dropbox?
Leave shared folders you don't need, delete files you no longer use, and remove backups you don't need. If you would rather keep everything, upgrade. Dropbox lists the same options, plus referral bonuses and promotions.
Step 1: Leave shared folders you don't need
This is often the fastest win. Dropbox says: "After you leave a folder, its contents no longer count toward your Dropbox storage quota." On dropbox.com, click Shared in the left sidebar, open the folder's more options menu, choose Remove from Dropbox, then Remove me. To rejoin later, the owner has to invite you again. (Dropbox Help, leave a shared folder)
Step 2: Remove duplicates
Paid plans have Find duplicates on dropbox.com: click the settings icon next to All files, then Organize, then Find duplicates. (Dropbox Help, find duplicate files) Basic has no duplicate finder. Find duplicate files in Dropbox covers both cases, and why a "conflicted copy" is not a duplicate.
Step 3: Delete the largest files you no longer need
On dropbox.com, hover over a file or folder, click the more options icon, choose Delete and confirm. Deleted files stop counting against your quota straight away, so there is no need to permanently delete them.
Step 4: Check Backup
If the storage bar shows Backup usage you didn't expect, a computer or external drive is being backed up into your account. To delete a backup, open the desktop app's account menu, then Preferences, Backups, Manage backups and Delete backup. (Dropbox Help, delete Dropbox Backup) Check the storage bar again afterwards to confirm the space came back.
How do you get deleted Dropbox files back?
Open Deleted files in the left sidebar on dropbox.com, check the files you want, and click Restore. They go back to the folder they came from. How long you have depends on your plan, as of October 2026 (Dropbox Help, recover deleted files):
| Dropbox plan | Recover deleted files for |
|---|---|
| Basic, Plus, Family | 30 days |
| Professional, Essentials, Standard, Business | 180 days |
| Advanced, Business Plus, Enterprise, Education | 365 days |
A data disposition policy can remove some files sooner.
How do you free up Dropbox space on your computer or phone?
On a computer, make files online-only or use selective sync. On a phone, turn off offline access for files you don't need on the device. Neither changes your Dropbox quota.
- Online-only (Windows or Mac): right-click a file or folder in your Dropbox folder and choose Make online-only. It stays visible but takes no space on your drive. Opening it downloads it again, so you need enough free space for that file.
- Selective sync: in the desktop app's Preferences, open the Sync tab and click Modify to uncheck folders. Unchecked folders are removed from your computer and "only stored on dropbox.com". Selective sync is available on every plan, including Basic. (Dropbox Help, selective sync)
- Phone or tablet: open the file's more options menu and turn off Make available offline. Dropbox's mobile page says: "removing files you've made available offline will free up space on your phone." (Dropbox Help, mobile storage)
How does The Drive AI find what is filling a Dropbox?
The Drive AI's file agent works inside your connected Dropbox with your own Dropbox permissions. Ask in plain English:
What is taking up the most space in my Dropbox? List the biggest folders and every file over 500 MB.- It measures folders. It summarizes a folder's whole subtree (file counts, total size, file types, date range), so the biggest folders show up without opening each one.
- It finds files by type, size or date, counts every match and their total size, and shows the largest.
- It finds identical duplicates by Dropbox's own
content_hash, and lists look-alikes to compare. Look-alikes are never removed automatically. - It proposes, then waits. Any removal is one plan you approve first, and it can be undone. Removed files go to Dropbox's Deleted files, where they stop counting against your quota and stay recoverable.
It works on your files and folders, so check the Backup and Replay segments of the storage bar yourself. Working in a connected Dropbox needs a Max or Team plan.
Frequently Asked Questions
Why is my Dropbox storage full but there are no files?
Shared folders you've joined count against your quota even though you didn't upload them, and Dropbox Backup and Replay use space outside your file list. Check the storage bar under Manage account: it splits usage into regular files, shared files, Backup and Replay. Deleted files don't count, so emptying them won't help.
Do shared folders count against my Dropbox storage?
Yes. Dropbox counts a shared folder against the quota of every member who has joined it, unless all of them are on the same Standard, Advanced or Enterprise team or the same Family plan. Shared folders you haven't joined don't count. Leaving a folder takes it off your quota.
Do deleted files count against Dropbox storage?
No. Dropbox says deleted files don't count against your storage quota, so permanently deleting them won't free space. Leave them in Deleted files until your plan's recovery window ends: 30 days on Basic, Plus and Family, and 180 or 365 days on the other plans, as of October 2026.
Does making Dropbox files online-only free up space?
It frees space on your computer, not in your Dropbox account. Online-only files stay stored on dropbox.com and keep counting against your quota. Use online-only or selective sync when your disk is full, and delete files or leave shared folders when your account is full.
Start with the storage bar, leave the shared folders you don't need, then clear the largest files and duplicates. To find the biggest folders and files in one request, connect Dropbox and ask The Drive AI: What is taking up the most space in my Dropbox? List the biggest folders and every file over 500 MB, and do not delete anything. If your Google account is the one that is full, Google Drive storage full covers the same steps there.
