Using command “forfiles” in Windows

C:\Users\Vichhaiy>forfiles /?

FORFILES [/P pathname] [/M searchmask] [/S]
[/C command] [/D [+ | -] {MM/dd/yyyy | dd}]

Description:
Selects a file (or set of files) and executes a
command on that file. This is helpful for batch jobs.

Parameter List:
/P pathname Indicates the path to start searching.
The default folder is the current working
directory (.).

/M searchmask Searches files according to a searchmask.
The default searchmask is ‘*’ .

/S Instructs forfiles to recurse into
subdirectories. Like "DIR /S".

/C command Indicates the command to execute for each file.
Command strings should be wrapped in double
quotes.

The default command is "cmd /c echo @file".

The following variables can be used in the
command string:
@file – returns the name of the file.
@fname – returns the file name without
extension.
@ext – returns only the extension of the
file.
@path – returns the full path of the file.
@relpath – returns the relative path of the
file.
@isdir – returns "TRUE" if a file type is
a directory, and "FALSE" for files.
@fsize – returns the size of the file in
bytes.
@fdate – returns the last modified date of the
file.
@ftime – returns the last modified time of the
file.

To include special characters in the command
line, use the hexadecimal code for the character
in 0xHH format (ex. 0x09 for tab). Internal
CMD.exe commands should be preceded with
"cmd /c".

/D date Selects files with a last modified date greater
than or equal to (+), or less than or equal to
(-), the specified date using the
"MM/dd/yyyy" format; or selects files with a
last modified date greater than or equal to (+)
the current date plus "dd" days, or less than or
equal to (-) the current date minus "dd" days. A
valid "dd" number of days can be any number in
the range of 0 – 32768.
"+" is taken as default sign if not specified.
