Missing Files after doing cmd z moving a folder

[MIB93]

Hi, So I was moving a folder from one drive to another in osx 10.85 the folder was 8gb I changed my mind to where I wanted to move it quite quickly and used cmd-Z to undo. Now I have the folder on both drives but the data inside has gone. I tried a redo but nothing changes. I know it must be there still (I hope) is there a way to get my data back?

Thanks

There is a way: from your backup.
Since you ended the process in progress, you might very well have lost the files.
If you had been doing a Copy, then the files would still be in their original location.
