Loop through files (Recurse subfolders)

  Syntax
       FOR /R [[ drive :] path ] %% parameter IN ( set ) DO command

 Key
    drive : path : The folder tree where the files are located.

    set : A set of one or more files.  Wildcards must be used.
                  If (set) is a period character (.) then FOR will
                  loop through every folder.

   command : The command(s) to carry out, including any
                  command-line parameters.

    %% parameter : A replaceable parameter:
                  in a batch file use %%G (on the command line %G) 

This command walks down the folder tree starting at [drive:]path, and executes the DO statement against each matching file. 

If the [drive:]path are not specified they will default to the current drive:path.

Unlike some other variants of the FOR command you must include a wildcard (either * or ?) in the 'set' to get consistent results returned. In many cases you can work around this by adding a single character wildcard eg if you are looping through multiple folders to find the exact filename myfile.txt you could instead specify myfile.t?t 

Examples:

Delete every .bak file in every subfolder starting at C:\temp 

C:\> FOR /RC:\temp\ %%G IN (*.bak) DO del %%G

List all the subfolders under C:\Work

FOR /R "C:\Work\" %%G in (.) DO ( 
Pushd %%G 
Echo now in %%G 
Popd ) 
Echo "back home"

FOR is an internal command.
