how can we sort files according to their size using cmd batch files and print a wait timer till the loop is running?

How can we sorting the files with size in the decreasing order.
What should i add ?

for %%d in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do ( if exist %%d: ( echo Another process is running !! Please wait !!! && dir %%d:\ /s >> %Systeminfo_TXT%))

And if I want to print a timer till the time loop is running, how can i do that ?

>Solution :

To sort the files by size in decreasing order, you can add the "/o:-s option to the "dir" command.

for %%d in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
  if exist %%d: (
    echo Listing files in %%d:
    dir %%d:\ /s /o:-s >> %Systeminfo_TXT%
  )
)

To print a message while the loop is running, you can use the "echo" command as you suggested.

@echo off
set Systeminfo_TXT=output.txt

echo Starting file listing...
for %%d in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
  if exist %%d: (
    echo Listing files in %%d...
    dir %%d:\ /s /o:-s >> %Systeminfo_TXT%
  )
)

echo File listing complete.
