To ECHO Hex characters in the Command use: 0xHH

Examples:

To find every text file on the C: drive
FORFILES -pC:\ -s -m*.TXT -c"CMD /C Echo @FILE is a text file"

To show the path of every HTML file on the C: drive
FORFILES -pC:\ -s -m*.HTML -c"CMD /C Echo @RELPATH is the location of @FILE"

List every folder on the C: drive
FORFILES -pC:\ -s -m*. -c"CMD /C if @ISDIR==TRUE echo @FILE is a folder"

For every file on the C: drive list the file extension in double quotes
FORFILES -pc:\ -s -m*.* -c"CMD /c echo extension of @FILE is 0x22@EXT0x22"

List every file on the C: drive last modified over 100 days ago
FORFILES -pc:\ -s -m*.* -d-100 -c"CMD /C Echo @FILE : date >= 100 days"

Find files last modified before 01-Jan-1995
FORFILES -pc:\ -s -m*.* -d-010195 -c"CMD /C Echo @FILE is quite old!"

note:
'0x22' is hex 22 - the double quote character - put these around any long filenames.

Version 1.0 of FORFILES will only search for files newer than a specified date.
Version 1.1 (described above) can search for file dates Newer or Older then a specified date.
The Vista/2003 version of ForFiles is not compatible with Windows 2000

An alternative method of dealing with files older or newer than a specified date is to use ROBOCOPY
