Generally Scanner and Rebuilder have absolutely nothing in common. The scanner is setbased, the rebuilder filebased. The rebuilder only copies files from a given source to a given destination by a hash compare. It rebuilds anything it finds and which is valid (crc32/size match). It doesn't know anything about completeness of sets etc.

The scanner goes through all sets and does countless more tests (unneeded, checksum, size, name, etc...) and fixes them in place.

If you drag&drop files into the scanner, the current rebuilder options are used and in this case the rebuilder can be used as an 'Adder', adding missing files to your collection.

but as mentioned, generally Scanner and Rebuilder are two totally different things.
