Sync Panes with SHA-256 hash comparison

Panes > Sync Select > Select Different
Now it checks different size or modified date
Can you add SHA-256 hash comparison?

Select "Overwrite if different contents". It uses SHA-256 hash comparison.

Where can I find such an option? That's all I've got.

You're probably talking about Sync Folders and what I'm asking is to add the same hash functionality for Sync Select.

Yep, you got it!
My mistake, I will add that function to Sync Panes later... good idea.
PS: Since content comparison is much slower I will add a new option "Select Different Content".

Great! Speaking of a speed, is there a way to use a faster hash function?

AFAIK Blake is not supported by the Windows API:
https://docs.microsoft.com/en-us/window ... yptography
There are tweaks in XY already now where you can choose SHA-1 or SHA-512:
Code: Select all
v22.00.0004 - 2021-07-02 15:39
+ Added three tweaks to control the hashing method used by the content check
in Custom Copy/Move, Backup, and Sync Folder. Each of them
factory-defaults to 4 (SHA-256):
ContentCheck=4 '1=ByteToByte, 2=MD5, 3=SHA-1, 4=SHA-256, 5=SHA-512
BackupContentCheck=4 '1=ByteToByte, 2=MD5, 3=SHA-1, 4=SHA-256, 5=SHA-512
SyncContentCheck=4 '1=ByteToByte, 2=MD5, 3=SHA-1, 4=SHA-256, 5=SHA-512
Any other value than the listed ones will fall back to 4 (SHA-256).
