USE CASES

When to use Compare two folders?

Compare two local folder trees without modifying files, distinguish added, removed, modified and identical content, then export a verifiable report.

CONCRETE EXAMPLE

BEFORE

Folder A: 1,240 files · Folder B: 1,252 files

→

AFTER

18 added · 6 removed · 9 modified · 1,219 SHA-256 identical · CSV report

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Quick mode never claims same-size files are identical: it leaves them as “Review”.
Browsers do not expose empty folders, symbolic links or permissions, so those elements are not compared.
A rename or move appears as one removal plus one addition; WorkToolset does not automatically infer identity across different paths.
Exact SHA-256 must read candidate files and can use substantial memory for very large files.
WorkToolset never moves, renames or deletes original files.

HOW IT WORKS

1Choose A as the reference and B as the newer version.
2Use Exact mode to SHA-256 only files that share the same relative path and size.
3Filter changes or display confirmed identical content.
