Identify files that should be copied into an incremental backup by comparing a source folder with a baseline folder. The result is a practical manifest of new and changed candidates.
Compares relative paths between two folder trees and selects source files that are absent from the baseline or have different size or modification time.
Your selected files stay in this browser session. Selection uses size and timestamp signals, not content hashes. Deleted source files are not included because an incremental copy cannot restore deletions by itself.

| Item | Support |
|---|---|
| Input | Parent folder with two sets |
| Output | JSON incremental manifest |
| Processing | Local browser session |
Put the older backup folder first by name and the current source second inside one parent folder, then review the manifest before copying.
Choose the requested files in this page and run the tool. Processing happens in your browser, and only the result you download leaves the page.
It contains the actual result or evidence produced from the selected file bytes and metadata, with the important findings shown on screen as well.
Browser memory and device speed set the practical limit. Start with a smaller sample if the file is several gigabytes or the device has limited memory.
No. Browser file access is read-only here. The tool creates a separate result for download and does not overwrite the selected originals.
No. The result covers the checks described on this page. Use specialized desktop or forensic software when you need deeper validation.
