Note
Forfiles is most commonly used in batch files.

Forfiles/s is similar to dir/s.

The following table lists the variables that can be used in the/cCommand command string.

Variable	Description
@ File	File Name
@ Fname	File name without extension
@ Ext	File Extension
@ Path	Complete file path
@ Relpath	File relative path
@ Isdir	If the file type is directory, the calculated value is TRUE; otherwise, the value is FALSE.
@ Fsize	File Size in bytes
@ Fdate	The Last modified Date stamp in the file
@ Ftime	The last modified timestamp in the file.

Using forfiles, you can run commands on multiple files or PASS Parameters to multiple files. For example, you can run the TYPE command on all files with the *. txt extension in the tree. You can use the file name extension myinput.txt as the first parameter to execute each batch of files (*. bat) on the C: \ drive ).

By using forfiles, you can perform any of the following operations:

Use/d to select a file based on the absolute or relative date.

Use variables such as @ fsize (file size) and @ fdate (File date) to construct the File Archive tree.

Use the @ isdir variable to differentiate files and directories.

You can format the output content by including special characters in the command line and using the hexadecimal code 0xHH.

Forfiles works by executing the "loop subdirectory" mark on a tool that is intended to process only a single file.
