Hi, I have 2 comments to the help file topic "Folder Pair Options":
1. Referring to
"Save overwritten files in the Recycle Bin:" ... "If this option is unchecked, the older file is overwritten with the newer file or, if it's being deleted, it is deleted permanently. The older file can not be recovered in that case, but less disk space is used."
I think you should indicate that for Vista users, it may not be necessary to turn the option on, because the file can usually be recovered also by using the Previous Versions feature.
2. Referring to
"Check file contents: This option is off by default. When running with “check file contents” selected, SyncToy will perform a SHA1 hash against all files. This hash, which is mathematically guaranteed to produce a unique value for the file's content, is used to compare files when determining whether files on both sides of the folder pair are already in sync."
Unless I'm seriously mistaken, I don't think the hash gurantees a unique value for each file. It only gurantees different values for different files.

Michael
