Does DeltaWalker Classic Support macOS Resource Forks?
A resource fork is a macOS file system construct used to store structured data in a file, alongside the unstructured data stored in its data fork.
DeltaWalker Classic supports resource forks as follows:
- Operations such as copy and move are aware of resource forks and, when present, copy or move them along with the files’ data forks.
- The Permissions column of a folder comparison shows ’@’ at the end for files with resource forks, as the screenshot below illustrates.
- The tooltips of files with resource forks show the resource fork size; see the screenshot.
- A byte-by-byte comparison of files with resource forks compares the data forks and, if they are the same, the resource forks.
