Following command works fine with one type of files ,
forfiles -p \"C:abc\\del\" -s -m *.exe -d -70 -c \"cmd /c echo @path\"
Is it possible
It's also possible to traverse the directory structure in a single pass and test each file extension with an IF.
forfiles -p c:\ -s -c "cmd /c (if @ext==\"exe\" echo @path) & ( if @ext==\"dll\" echo @path) & ( if @ext==\"xyz\" echo @path)"
Just remember to escape the inner quotes \"dll\" instead of "dll", because the whole command is in a single string.
