Question : After Robocopy has finished the new folder disappears in Windows, but is available in DOS

I need to use Robocopy to copy away a large amount of image data to a backup drive.
I have had success with 3 local drives being copied & the first time I ran the script for the 4th drive it worked fine.
But I ran the 4th script again & after it had finished the folder that it creates on the backup drive is no longer visible in Windows Explorer. This same folder is accessible in DOS..
I cannot use the RMDIR command to delete this hiding folder, it returns an access denied error.

Just wondering if it is to do with folder properties or something I should add to the script. The script I used was very basic.

Answer : After Robocopy has finished the new folder disappears in Windows, but is available in DOS

If the folder does not exist, robocopy creates it and marks it as a system folder. One way around this is to create the folder first, then run robocopy.
