Exclusions are only available in multi-destination mode. They're the mechanism for saying "don't migrate this folder, but do migrate everything around it."
Typical reasons:
~snapshot, .DS_Store directories, backup artifactsExclusions don't delete anything from the source; they just tell CloudMove not to migrate that content.
In the source tree (multi-destination mode), click the folder and choose Exclude from the destination choice modal.

The folder appears in the Excluded tab on the right. Its children inherit the exclusion — nothing inside gets migrated.
Excluding a parent and then mapping a specific child to a destination does re-include that child. The most specific mapping wins.
Example:
\\fileserver\Archive → Excluded\\fileserver\Archive\2025 → mapped to SharePointResult: only \\fileserver\Archive\2025 migrates. Everything else under Archive is skipped.
In the Excluded tab, click the undo icon on any entry. The folder reverts to unmapped and will inherit its parent's destination again.
Scans still analyze excluded folders — you'll see their issues in scan results. But during migration, excluded folders are entirely skipped.
This is intentional: the scan shows you what's in the source, even if you're not migrating it. Helps when you want to double-check before finalizing exclusions.
