Hello
Do you mean you want to move the files from the lash drive to your new computer?
If so, in your new computer, I assume it is a Windows 11 computer? Then go to File explorer > This PC, do you see the flash drive listed? It can be listed as D drive in most common case, double click and access it. Then find the files or folders you are looking for, right click, choose copy, then go to the folder you want to move them to, right click and choose paste.
