Is SyncToy 2.1 much faster than 2.0

"Again I've stayed with SyncToy v1.4, as I found v2.1 to be also too slow to be of any use.

First I ran v1.4 to make sure everything was already synched and echoed, and then I installed v2.1 over v1.4 (which kept its settings and upgraded it).

Then I previewed two known-to-be-identical folders, each 7.16Gb (containing 53,817 Files and 2,594 Folders). SyncToy v2.1 took 11 minutes and said that it would need to overwrite 46,650 files (and that 60,972 files did not require action). This was too slow and was incorrect about having to overwrite any files.

So I uninstalled v2.1 and reinstalled v1.4, and did the same test. This time it took 2 minutes to compare the same folder pair and no files needed copying (except for a few SyncToy_*.dat files left by v2.1)."

"Syntoy 2.1 doesn't decrypt encrypted files and folders whereas Synctoy 2.0 won't copy file attributes such as for encryption.

When using version 2.0 all my encrypted files and folders are decrypted.

This occurs when copying between two NTFS formatted drives. If copying between an NTFS and FAT drive encryption and NTFS file attributes should be automatically removed.

I'm uncertain about ver. 1.4. Previous download links are broken and MS replaced the 1.4 download link with version 2.0.

If you have many encrypted files to copy to a removable drive, you don't necessarily want backup files and folders to be encrypted when attached to other PCs.

I remember Synctoy 2.1 being somewhat faster than ver. 2.0 but haven't actually performed any testing, 2.1 seems to be faster.

I have both 2.0 and 2.1 (x64) installed. Perhaps MS should have added some sort of option(s), but wanted to keep Synctoy simple as possible.

If you have many encrypted files that need to be decrypted. When using ver. 2.1 you would need to add additional time for decrypting hundreds to thousands of files vs the amount of time it takes version 2.0."
