From "Technical Notes on SyncToy" in SyncToy Help:
•SyncToy uses the following folder to store data used to facilitate synchronization operations: On Windows Vista: %LOCALAPPDATA%\Microsoft\SyncToy\2.0\, On Windows XP: "%USERPROFILE%\Local Settings\Application Data\Microsoft\SyncToy\2.0\" •The SyncToyDirPairs.bin file is used to store data describing the folder pairs that have been created with the local instance of SyncToy. •At the root of each of the folders associated with a folder pair is a marker file with the following naming convention: SyncToy_[ID].dat. ID is a unique identifier to allow SyncToy to locate each root folder being synchronized. The marker files are used to enable the dynamic drive letter assignment feature. •SyncToy does not allow editing of the left or right folder in a folder pair because changing either path invalidates the stored snapshot and disables -- for the next run at least -- many of SyncToy's most important features.
Thank you for the comprehensive explanation of SyncToy. I use the "Echo" mode in order to modify the files on the Left "C" which then are changed on the Right "D" side.
However, my question was about the Registry. Is there a separate folder containing the Registry and if so where is it? If not, is there a way for me to use the SyncToy in the "Echo" mode so that changes in the Registry on the Left "C" are reflected on the Right "D".
