Hello,
When copying files, the source path is too long, which can generally be solved by enabling long path support by Group Policy in Windows:
Open the local Group Policy Editor (gpedit.msc) and navigate to: Computer Configuration> Management Templates> System > File System, find "Enable Win32 Long Path" and double-click to open it. Select the "Enable" option and click "OK" , then restart your computer.
However, this method only works on Windows Server 2016, Windows 10 and above, Windows server 2008 is not covered by technical support, you may consider using a third-party tool to resolve this issue.
I hope this information helps.
Best regards,
Jingjing Wu
