How to use Incremental Backup File Selector

  1. Select Parent folder with two sets using the file area.
  2. Review the selected filenames and sizes.
  3. Choose any available options and click Build Incremental List.
  4. Read the findings, then download the JSON incremental manifest.

What this file tool does

Compares relative paths between two folder trees and selects source files that are absent from the baseline or have different size or modification time.

The first top-level folder is treated as the baseline and the second as the source. The output manifest records the copy reason and source metadata.

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.

Example and practical tips

Practical example

Put the older backup folder first by name and the current source second inside one parent folder, then review the manifest before copying.

Tips

  • Keep an untouched copy of important source files.
  • Check filenames and sizes before downloading the result.
  • Use a current desktop browser for the broadest file API support.

Frequently asked questions

How can I use incremental backup file selector without uploading files?

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.

What does the downloadable json incremental manifest contain?

It contains the actual result or evidence produced from the selected file bytes and metadata, with the important findings shown on screen as well.

Can I use incremental backup file selector on a large file?

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.

Does this tool change my original files?

No. Browser file access is read-only here. The tool creates a separate result for download and does not overwrite the selected originals.

Is a clean result a complete security guarantee?

No. The result covers the checks described on this page. Use specialized desktop or forensic software when you need deeper validation.
