/EXCLUDE:filename
Excludes the files listed in the specified file from the

are supported). If any exclusion pattern in the file matches
any part of the path of a subject file, that file is not copied.
Examples
Copy only files older than Christmas day 2000:
FOR /F "tokens=1* delims=:" %%A IN ('XCOPY *.* D:\Mydir /D:12-25-2000 /H /I /L /R ˆ| FIND ":"') DO (>>%TEMP%.\exclude.lst ECHO.%%B)
XCOPY *.* D:\Mydir /EXCLUDE:%TEMP%.\exclude.lst /H /I /R
Delete files created or modified after Christmas 2000:
FOR /F "tokens=1* delims=:" %%A IN ('XCOPY *.* D:\Emptydir /D:12-26-2000 /H /I /L /R ˆ| FIND ":"') DO DEL /F %%B
