# Better Performance: The speed of file copy operations is significantly increased across the board.
# Improved Robustness: Much more resilient to transient network and file system errors and better error reporting which pin-points which file the sync failed on in case thereâ€™s a fatal error that stops the sync.
# Folder pair configuration backup: Folder pair configuration is automatically backed up under %localappdata%\microsoft\synctoy\2.0. User can replace SyncToyDirPairs.bin with the backup copy to resolve last saved configuration.
# Bug Fixes:
* Fixed the data corruption issue when using SyncToy with NAS drives.
* Fixed the issue that prevented uploading files to SharePoint when using SyncToy 2.0.
* Fixed the issue that prevented delete changes from being synchronized when the sync option is set to â€œEchoâ€.
* Fixed the UI issue where reported file time were off by the difference between local time and UTC when destination is a FAT volume.
