Windows – List files recursively showing only full path and file size from Windows Command Prompt

command linewindows

I am trying to generate a text file containing the filename (including full path) and file size for all files in a particular directory and any of its sub-directories (i.e. recursively). Ideally, I don't want commas in the file size (but I'll settle for them!)

The following command does it but without the file size:

dir /b /s /a:-D > results.txt

An example output would look like:

C:\Users\Martin\Pictures\Table\original\PC120013.JPG  227298
C:\Users\Martin\Pictures\Table\original\PC120014.JPG  123234
C:\Users\Martin\Pictures\Table\original\PC120015.JPG  932344

I don't think this is possible using dir alone, although I would love to be proved wrong.
Is there another way to do this, using only commands that are available from the Command Prompt?

This should do it:

@echo off & for /f %a in ('dir /s /b') do echo %~fa %~za

It's not very efficient...running it for folders containing a ton of files may be sketchy, so try it on small folders first.

From the "for /?" help text (I used 'a' instead of 'I')

In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line
