Folder vs folder, byte for byte
Two folders.
Every difference.
FolderManifest walks both folder trees and hashes every file — then shows changed, missing, renamed, and identical files in one interactive report. Verify backups, migrations, and mirrors with proof.

The first useful result
In one scan, you know what changed.
The trial gets you to the aha quickly: choose the source and mirror, run the comparison, and inspect the exact files that are missing, changed, renamed, or identical.
- 01
Choose both folders
Use local disks, USB drives, NAS shares, or any two readable locations.
- 02
Run the content diff
FolderManifest hashes the files so timestamps and names cannot hide drift.
- 03
Act with evidence
Filter the interactive report, export it, and reconcile only what truly differs.

Where two folders meet
Copy tools promise. Folders drift.
Interrupted copies, selective sync, offline edits — plenty of things leave two “identical” folders quietly different. A content diff ends the debate.
01 / BACKUPS
Trust, but verify
Your backup tool says success. Compare source vs mirror by content and get the actual truth — including the one truncated file it forgot to mention.
02 / MIGRATIONS
Old server → new server
After the copy job, compare old share against new share. When the report shows zero differences, decommission with your eyes open.
03 / TWO MACHINES
“Which copy is current?”
The laptop folder and the desktop folder diverged weeks ago. Diff both trees and see exactly which files changed on each side — then reconcile deliberately.
How it works
Walk both trees. Report the truth.
1
Choose folder A and B
Pick the two trees to compare — across disks, machines, or network shares.
2
Recursive hash & diff
Every file on both sides is hashed with SHA-256; matches, changes, and one-side-only files are grouped.
3
Review and export
Explore the interactive report, filter by state, export HTML or CSV — evidence both sides can see.

Verify before you trust
“Success” is a claim.
A diff is evidence.
Sync logs summarize; FolderManifest itemizes. When the two folders truly match, the report says so — and when they don't, you get names, not vibes.

Questions
Before you diff
How do I compare two folders in Windows?
Built-in options exist (robocopy /L, dir diffs) but they compare names and sizes, not content. FolderManifest hashes every file on both sides with SHA-256 and shows changed, missing, added, and identical files in one interactive report.
Will it detect files that were renamed?
Yes. Renamed-but-identical files appear as content matches at different paths, so you can see the rename instead of a confusing pair of “missing” and “new” files.
Can I compare a folder against a backup or mirror?
That’s the classic use: point one side at the source, the other at the mirror, and get byte-level proof of what matches and what drifted — before you trust or delete either side.
Does it work across drives and network shares?
Yes — internal disks, USB drives, NAS shares, and cloud storage mounted as drives. Any two locations Windows can read can be compared.
Can I try it without installing anything?
Yes — the free Folder Compare Online tool diffs two folder uploads right in your browser with recursive SHA-256 checks. No sign-up, no install.
Is folder comparison included in the trial?
Yes. The seven-day full-access trial includes folder compare, integrity monitoring, duplicate finding, Safe Archive, and the CLI. One $59 lifetime license keeps everything.
