A Dropbox conflicted copy is a second version of a file that Dropbox creates when the same file is changed in two places at once, and Dropbox says the last version saved is always the one labeled as the conflicted copy. Which file to keep depends on whether the two actually differ: if they are byte-for-byte identical, the conflicted copy is redundant, and if they differ, you need to compare and merge. DupeDoctor from Automata Labs confirms exact duplicates by content on Windows, so you can separate the identical copies from the ones that hold real changes.
Find byte-identical copies by content, not by name, and send the extras to the Recycle Bin.

What is a Dropbox conflicted copy?
Dropbox’s help article What’s a conflicted copy? defines it as “a file that Dropbox creates when multiple people edit the same file at the same time.” Dropbox adds the editor’s username, the words “conflicted copy” and the save date to the filename, so it sits next to the original with a longer name.
Dropbox lists three ways it happens:
- Two users change the same file at the same time.
- Someone edits a file offline while someone else edits the same file.
- A file is left open on another user’s computer, which Dropbox saves as a new edit, which it calls “especially common when using applications with an auto-save feature.”
The same thing can happen with one person and two computers, for example a laptop that was offline while you edited the file on a desktop.
Which version is the conflicted copy, the newest or the oldest?
Per Dropbox: “The last version saved will always appear as the conflicted copy.” So the file with “conflicted copy” in its name holds the most recent save, and the file with the original name holds the earlier one. That surprises many people, who assume the conflicted copy is an old leftover and delete it.
| File | What Dropbox says it holds | Common mistake |
|---|---|---|
| Original name | The version saved first | Assuming it has the latest edits |
| Name with “conflicted copy” | The last version saved | Deleting it as a stale duplicate |
Should I delete the conflicted copy?
Only after you know what is in it. There are two very different situations:
- The files are identical. This happens when an app re-saves a file without real changes, such as auto-save on a document left open. Keeping both just wastes space and causes confusion. Removing the conflicted copy loses nothing.
- The files differ. Each one contains edits the other does not. Dropbox’s advice is that “the best way to resolve a conflicted copy is to compare both versions and merge them manually.” For Word documents, Dropbox points to Microsoft’s compare and merge feature.
The trap is that you cannot tell which situation you are in from the names, dates or sizes. Two files of the same size can still differ by one changed character.
How do I tell if a conflicted copy is identical to the original?
Compare the content, not the metadata. The reliable way is a cryptographic hash: if two files produce the same hash, they are the same bytes. You can do that one pair at a time with a command line hashing tool, or across a whole folder with a duplicate finder that verifies by content.
DupeDoctor’s Microsoft Store listing describes exactly this approach: “a quick size grouping prunes the obvious non-matches, then a fast BLAKE3 hash verifies true byte-for-byte copies, so renamed files are still caught.” That last part matters here, because a conflicted copy always has a different name from the original.
A cleanup routine for a Dropbox folder:
- Let Dropbox finish syncing so you are not comparing files mid-update.
- Scan your Dropbox folder, or just the project folder that has the conflicts.
- Use Filter by path to focus on the folder you care about.
- Review the exact duplicate sets. Any conflicted copy that appears in a set with its original is identical and safe to remove.
- Any conflicted copy that does not appear in an exact set differs from the original. Open both, compare and merge.
How do I clean up many identical conflicted copies at once?
DupeDoctor’s listing describes one-click auto-keep rules, “keep newest, oldest, or shortest path,” which pre-select the redundant copies in exact sets. Because Dropbox appends text to the conflicted file’s name, a shortest path rule will usually keep the original name, but check the selection before you remove anything.
Its safety rules, per the listing:
- Deletion “always goes to the Windows Recycle Bin,” and there is no permanent-delete path.
- “At least one file in every duplicate set is always kept.”
- You can move selected extras to a folder instead of recycling them.
- You can export a full report of what was found as CSV or JSON.
Clear out identical copies with keep rules, undo and a Recycle Bin safety net.

Two cautions of our own. First, a file removed inside your Dropbox folder is a change Dropbox syncs like any other, so if the folder is shared, think before cleaning someone else’s files. Second, DupeDoctor can replace exact duplicates with hardlinks, but we suggest not using hardlinks inside a cloud-synced folder, since sync clients are built around ordinary files.
What if I deleted the wrong version?
Dropbox keeps earlier versions of files. Its article on recovering older versions explains that you can right-click a file in File Explorer and select Version history to preview and roll back. How far back you can go depends on the plan:
| Dropbox plan | Version history window |
|---|---|
| Basic, Plus, Family | 30 days |
| Professional, Essentials, Standard, Business | 180 days |
| Advanced, Business Plus, Enterprise | 365 days |
Locally, anything DupeDoctor removed is also in the Windows Recycle Bin until you empty it.
How do I stop conflicted copies from happening?
Dropbox’s own suggestions:
- Collaborate in real time with an app built for it, such as Dropbox Paper or Microsoft Office Online.
- If you cannot collaborate in real time, move the file out of the Dropbox folder while you work on it, then move it back.
- Create an “In Use” folder for files being edited so collaborators know to wait.
- On Dropbox teams, coordinate when the Dropbox badge shows someone else is editing.
From experience: close files you are not editing, especially in apps that auto-save, and let a laptop finish syncing before you start working on shared files. If files seem locked or out of date while syncing, see Dropbox or Google Drive file locked on Windows. For the OneDrive version of the same clutter, see OneDrive duplicate files with your computer name.
Frequently asked questions
Is the conflicted copy newer than the original?
Dropbox says the last version saved always appears as the conflicted copy, so yes, it holds the later save.
Can I just rename the conflicted copy back to the original name?
Only after you have decided which content to keep. Renaming over the original replaces its content.
Why do I get conflicted copies when I am the only user?
The same file can be edited from two devices, or an app can save a file that is open on another computer you own.
Does DupeDoctor find conflicted copies by name?
It groups the “file (1)” style of copy name, but conflicted copies are found as exact duplicates by content when they are identical, regardless of name.
Can DupeDoctor merge two different versions?
No. It finds and removes identical copies. Different versions need comparing and merging in the app that created them.
