Don’t let your photos and videos and other data become corrupt without being able to easily detect bit rot or file corruption. Rather, prove that your data is 100% intact, whether it be your originals or the 10th backup of a backup, on a SSD or hard drive or NAS or a download or to/from the Cloud.
The key new feature is extended file attributes (xattrs) in addition to the icjh files, supported on macOS and Linux*. This new feature is completely seamless (nothing new to learn).
In particular, extended file attributes store hash info in addition to the icjh files.
This comprehensive and unrivalled solution means that all files can be covered, and that hash info travels seamlessly with files that are moved. Even into the Cloud (macOS, iCloud and similar).
* Windows has no support for extended file attributes; there is no apparent way to support the feature.
Linux works well with attributes, but is inferior to macOS in that it has limited intelligence on preserving attributes during file copy or similar.
