How to Transfer Files from Dropbox to OneDrive

The fastest way to move, copy or migrate files from Dropbox to OneDrive is a direct cloud-to-cloud transfer: your files go straight from one provider to the other without ever being downloaded to your computer. Cloud Combo does this for free, for files and whole folder trees, with live progress.

Dropbox's free plan tops out at 2 GB, which many users outgrow quickly. OneDrive is the obvious choice if you use Microsoft 365 — 1 TB of storage is included with most subscriptions. Whether you are switching for good, consolidating accounts, or just keeping a backup copy in a second cloud, here is the step-by-step process.

Step-by-step

  1. 1

    Create a free Cloud Combo account

    Sign up at cloudcombo.app — it takes under a minute and no credit card is required.

  2. 2

    Connect your Dropbox account

    From the dashboard, click "Add Drive" and connect your Dropbox account. You'll sign in with the provider directly via OAuth — Cloud Combo never sees your password.

  3. 3

    Connect your OneDrive account

    Add your OneDrive account as well. Both drives now appear side by side in your dashboard.

  4. 4

    Select the files or folders to move

    Open New Transfer, browse the source drive, and select any files or entire folders — nested folders transfer completely, keeping their structure.

  5. 5

    Pick a destination folder and confirm

    Choose where the files should land, review the total size, and start the transfer. It runs in the cloud — you can close the tab and watch live progress on the Transfer List page. It works equally well for a one-time migration or a periodic backup copy.

Good to know for this transfer

  • Cloud Combo uses Dropbox upload sessions for large files, so there is no 150 MB single-file limit — files of any size transfer.
  • Transfers into OneDrive use Microsoft's resumable upload sessions, chunking large files so they arrive reliably.
  • Transfers run server-side, so they continue even if you close your browser. Failed files are retried automatically and reported individually — one problematic file never stops the rest.
  • Every file is checksum-verified: the destination must confirm the exact bytes that left the source, or the file is automatically re-transferred.
  • Your files are never stored by Cloud Combo: they stream directly between Dropbox and OneDrive over encrypted connections, authorized via OAuth 2.0.
