Revisionist & DeepTools

Revisionist – opens up the full power of the macOS versioning system

revisionist09
Revisionist makes deep copies of documents with all their versions, and carries versions across iCloud Drive and other barriers. It also identifies and lists files with multiple versions, lists versions with details for individual files, previews them using Quick Look, and removes/deletes selected versions from the macOS database. New version fixes a bug in moving through the list of versions using the arrow keys.
Revisionist 1.7 (El Capitan, Sierra, High Sierra, Mojave and Catalina)

DeepTools – three quick and simple tools to preserve versions associated with your documents when copying or moving them

DeepCopy preserves versions when copying/moving within a local volume, or between volumes. DeepArchive and DeepUnarchive ensure complete mobility, keeping versions intact for other Macs on iCloud, when copying to memory sticks, networked storage (NAS), even sending documents by email, and with other operating systems including Linux/Unix and Windows. Now with interface improvements and compatible with Catalina.
DeepTools 1.3 (El Capitan, Sierra, High Sierra, Mojave and Catalina)
