Dropbox

ApplicationDropbox, Inc.

Also called dropbox desktop, dropbox sync

Dropbox, Inc.Productivity

A cloud sync client. The process is Dropbox.exe. OneDrive is Microsoft and a different product.

What you need to know

Dropbox syncs a folder. OneDrive is a different client on the same PC.

Dropbox.exe watches a directory and talks to Dropbox servers. Running it next to OneDrive on the same documents tree is how disks stay busy.

What is it?: A folder sync client
Need it if I use the site?: Only for Explorer sync
Same as OneDrive?: No

Feex says

If both clouds own the same folder, I would pick one. Ending Dropbox.exe only pauses that client. OneDrive will keep writing.

What is Dropbox?

Dropbox is Dropbox, Inc.'s sync client. Smart Sync placeholders can wake the client when Explorer opens a file.

If you have never used it

If someone shared a dropbox.com link, you can often download from the website. The Windows app is for a live folder in Explorer. Install it from dropbox.com/install. It is not OneDrive, not Google Drive, and not a Windows component. Two clouds on the same Documents tree is how disks stay busy.

What is it used for?

Folder sync

A Dropbox folder that mirrors the cloud. Dropbox.exe is the worker.

Sharing links

Right-click share from Explorer if the overlay is installed. The site can do the same.

Selective sync

Keep some folders online-only. Opening a placeholder wakes the client.

Who is it for?

People whose work already lives in Dropbox
Users who want Explorer overlays
Anyone who should not stack it on the same tree as OneDrive

Current status

Actively developed. This article is the Windows desktop client, not Dropbox Paper.

How old is it?

Dropbox launched in 2008 as an early consumer cloud folder. It is not a new app. OneDrive and Google Drive grew later on the same idea. Dropbox Paper is a docs product, not this sync client.

Installed processes

These executables belong to this product when it is installed.

Installed processes
Dropbox.exe	Sync client

Startup components

Dropbox can start with Windows from its own setting. That is the tray, not a Windows service.

File locations

Common Dropbox locations
Client	Under AppData\Local\Dropbox or Program Files, depending on the installer

File formats

whatever you store in the folder

Common problems

Two sync clients

Dropbox plus OneDrive on one tree double-writes. Move one root.

Explorer overlay lag

The shell extension rides explorer.exe. The worker is still Dropbox.

Getting unstuck

Pick one cloud root if OneDrive is also installed

Two clients writing the same tree double the disk. Move one folder.

Pause sync from the tray before you debug Explorer

The overlay rides explorer.exe. The worker is still Dropbox.exe.

Install from dropbox.com/install

A "Dropbox sync tool" from a search ad is the wrong file.

Alternatives

OneDrive, a mapped share, or the Dropbox website. Pick them for the account you already have.

Related hardware

An SSD makes the first sync hurt less. A spinning disk plus two clouds is the worst case.
