Wildcard file extensions xcopy

Solution 1:

In your command line:

 xcopy /C /D /Y /I "C:\Temp\Source" "C:\Temp\Destination" 

as far as I can see, you haven't told xcopy what to copy. If you're trying to copy everything in C:\Temp\*.* then try:

 xcopy C:\Temp\*.* C:\Temp\Destination\ /C /D /Y /I

Solution 2:

Use robocopy instead of XCOPY. It supports the same options and allows to select file patterns:

robocopy source dest file(s) [options]  

For file pattern you could use ? for any single character, * for zero to multiple chars and so on. It would help if you gave an example of how the extensions are looking like.
