Architect
Project folder to an external SSD every evening
The change journal picks up the 40 changed files in two seconds instead of rescanning 400,000.

Sync & Mirror
Change-journal driven sync that knows what changed in seconds and never deletes without a preview.
The problem
FreeFileSync rescans everything each run. robocopy /MIR deletes silently. SyncToy is gone.
Features
- NTFS USN journal detects changes without rescanning
- Three-way state database to detect true conflicts
- Diff preview before anything is deleted, with versioned trash
- Verified copies via the Copy Engine
- Scheduled or on-change runs through the Job Engine
Who it is for
Video team
Two editors sharing one drive
Three-way state detects edits on both sides and asks instead of overwriting.
Admin
VM export folder to the NAS
A scheduled mirror with versioned trash for exports that were deleted.
Benefits
- Mirrors in seconds instead of long scans
- Nothing deleted without a preview
- Conflicts detected, not silently overwritten
Built to be trusted
- Deletions go to a versioned trash with retention
- Journal gap detection triggers a safe full scan
- Never mirrors onto an empty target without typed confirmation
Good to know
USN only exists on NTFS and ReFS. On exFAT USB drives and network shares we fall back to a scan, like everyone else.
Under the hood
For technical readers
- FSCTL_READ_USN_JOURNAL and FSCTL_ENUM_USN_DATA
- ReadDirectoryChangesW fallback
- SQLite three-way state store
- Copy Engine
