I have using hundred of syncing tool…
with my huge data about 5 million files to mirror to about 30 server… and I tried so many special behavior like rename folder , rename file, even if copy fils in the same folder…
rename folder => auto detected and without tranfering the file, I think it’s just do the checksum and binary compare to transfer differ block…
rename file => too…
copy files in the same folder => detected and do the binary check and without any data between internet transfer
I have never seem tool do the “copy files in the same folder” check … It awasome best syncing tool
