This page is for your support questions and comments on my free utilities DeepTools (consisting of DeepArchive, DeepCopy and DeepUnarchive), which preserve versions of documents which are kept by macOS when their original files are copied or moved.
Full details, current versions, known issues, and much more about DeepTools are on this page.
You can also email me if you prefer: my address is given in the About page for this blog.
