Nested Duplicate Folder Finder
Select one large folder tree and find subfolders that were accidentally copy-pasted or duplicated at different paths within it.
How to use Nested Duplicate Folder Finder
- Start by providing the required input: Select the folder tree to scan.
- No additional settings need to be configured.
- This tool has no separate run button; its results update as you add or change the input.
- Review the result or preview on the page and confirm it matches your input before using or sharing it.
The copy-paste mistake that hides inside a large project
In a sprawling folder tree, it's easy for a subfolder to get duplicated at two different paths without anyone noticing — pasted once during a reorg, forgotten, then rebuilt independently somewhere else. Scanning every subfolder's combined content hash against every other subfolder's catches this automatically, no matter how deep it's buried.
Why this scans one big folder instead of separate selections
This is built for the single-folder-tree case specifically — select one large folder once, and every subfolder within it gets compared against every other subfolder in the same pass.
Does this compare every possible pair of subfolders?
Yes — every subfolder's content signature is computed and grouped, so any match anywhere in the tree is found regardless of how far apart the two copies are.
Will empty subfolders show up as duplicates of each other?
No — folders with no files are excluded from duplicate-group results, since an empty folder matching another empty folder isn't meaningful.
Comparing two separately selected folders instead?
Use the Duplicate Folder Matcher, built for checking whether two (or more) individually selected folders are duplicates of each other.
