I misspoke. small files are files < 64 bytes, (NOT kb!) Oops!
As I understand it, with windoze systems, when you modify a file, you completely rewrite it as a new file. Those blocks that belonged to the "old" file are maintained in the snapshot inode listing. This is not an issue with Unix (As I understand it). So with file folding, the contents of the active file system are compared against the most recent snapshot (only) to determine if blocks are duplicates and can be freed. Also, small files (less than 64K, which really are written to the inode) NT streams and directories are not folded.
