Dropbox offers two ways to send files: a shared link to something already in your Dropbox, and Dropbox Transfer, which delivers a copy with an expiry date. Both work well — until the files are bigger than the free 2 GB, the upload takes hours, or the recipient gets a ZIP instead of your folder. This StrongFolder vs Dropbox comparison explains which tool fits which job, including when Dropbox is clearly the better choice.

What is the main difference between StrongFolder and Dropbox?
Dropbox stores; StrongFolder sends.
Dropbox is a place where files live. You upload or sync them, they count against your storage, and a shared link lets anyone open, preview or download them for as long as you keep them. Dropbox's help center says you don't need a Dropbox account to download the files in a shared link. That is ideal for files people will come back to.
StrongFolder is a pipe. It moves files or folders from your device to another device and keeps nothing. Files are never uploaded to or stored on a StrongFolder server. To create the link, the service keeps transfer metadata: file and folder names, sizes and the number of files. The cost of that model: The sender's browser tab must stay open and online until the recipient finishes downloading — files come from the sender's device, not from a server.

What about Dropbox Transfer?
Dropbox Transfer is Dropbox's delivery feature: pick files, get a link, the recipient downloads a copy. On Dropbox Basic, the help center lists a 2 GB transfer size limit and a 7-day expiry; transfers are deleted 30 days after expiry. Custom expiry dates, passwords and branding are available on specific paid plans. The recipient doesn't need a Dropbox account.
StrongFolder works like a transfer too, but without the copy in the cloud: the recipient downloads from your browser, with no size limit set by the service. If you need the recipient to download days later, Dropbox Transfer is the better fit. Compare with other services in our list of WeTransfer alternatives.
Is StrongFolder a good Dropbox alternative for large files?
Yes, when the problem is size. Dropbox's help center says every file you upload must be smaller than your storage space, so on Basic a single 2 GB file fills the account. To share a 30 GB video through Dropbox, you'd need a paid plan with room for it, and then upload all 30 GB first.
StrongFolder has no storage to fill, so your plan doesn't matter. A 120 GB folder of camera footage goes straight from your disk to the editor's disk. The practical limits are the recipient's free disk space, your upload speed and both devices staying online. See how to send a 100 GB file free, send files without uploading and limits.
Does the recipient get the folder or a ZIP?
From dropbox.com, a ZIP. Dropbox's help center says folders download as compressed .zip files, and a folder can only be downloaded if it's smaller than 250 GB uncompressed and contains fewer than 10,000 files — files in nested folders count too. For large downloads, Dropbox recommends its desktop app.
StrongFolder sends the folder as a folder. The recipient picks a destination and the same subfolders and file names appear there, written file by file — no ZIP, no file-count ceiling set by the service. Saving a whole folder with its structure uses the File System Access API: Chrome, Edge, Opera and other Chromium browsers on a computer. Other browsers can download the files one by one or as a ZIP.

When is Dropbox the better choice?
Choose Dropbox when:
- the files already live in your Dropbox — sharing a link takes seconds;
- people will come back to the files over weeks, or edit and comment on them;
- you can't stay online while they download, or they'll download at different times;
- you need sync across your own devices, version history or access control;
- the recipient should download in a few days — Dropbox Transfer keeps the copy for them.
For a shared project folder that lives for months, Dropbox is the right tool, and StrongFolder doesn't try to replace it.
When is StrongFolder the better choice?
Choose StrongFolder when:
- the file or folder is bigger than your free Dropbox storage or the 2 GB Transfer limit;
- it's a one-off delivery — final footage, a photo shoot, a build, a dataset;
- the recipient should get a folder, not a ZIP, or the folder has more than 10,000 files;
- you'd rather not upload a copy to anyone's cloud;
- neither side wants to sign in — no account is needed;
- several people need it now — One link can be opened by several recipients; each downloads directly from the sender.
Keep your computer awake and the tab open until everyone finishes.

Can I use both?
Yes. Keep working files in Dropbox, and use StrongFolder for the heavy one-time transfers that would eat your storage or take hours to upload: raw footage to an editor, a project archive to a client, a big folder from a work computer to a home computer. If you prefer one click from the browser, the Chrome extension puts StrongFolder in your toolbar. The same logic applies to other drives — see StrongFolder vs Google Drive and StrongFolder vs OneDrive.
Summary
Dropbox is storage with sharing: best for files people will open over time, limited on the free Basic plan to 2 GB of storage and 2 GB per Dropbox Transfer that expires in 7 days. StrongFolder is a direct transfer: no upload, no storage, no size limit set by the service, folders kept as folders — as long as your tab stays open. Use Dropbox to keep files, StrongFolder to deliver big ones.
