I have a folder with images :

1.png
2.png
3.png
...
11000.png.

And I want to rename this files adding a p- as follows:

p-1.png
p-2.png
...
p-11000.png

How can I achieve this? I tried

ren *.png ???-p.* 

but this is giving the opposite results.

  • You can use either a batch script or a tool like den4b.com/products/renamer . Look also at the Related links on the right of this page. – FedonKadifeli Jul 14 '19 at 12:10
  • some more info on ren can be found here : superuser.com/questions/475874/… – Pathfinder Jul 14 '19 at 13:09
  • @NexussimLements .... Did you look over the cmd batch file rename method as described and such below which I wrote up for you a while back? – Pimp Juice IT Aug 23 '19 at 1:02
  • @Pimp Juice IT Yes , it worked like a charm. Thanks (I don't have enough reputation to upvote your answer.) – Nexussim Lements Aug 23 '19 at 10:24

Append a string (or characters) to the beginning of file names

You can use a for loop to iterate each file in a directory and use variable substitutions to get the specific name portion of each file. You can use those and add in the "p-" string and append it as a prefix with the ren command for each file getting the expected output result you desire.

Essentially this. . .

  • Iterates all *.* files in a specific directory (not recursively)
  • Uses variable substitutions for getting the file name portions from each file
  • Appends the p- string to the beginning of each files and passes that per file as the second argument to the ren command for the new name

Command Line

for %a in ("C:\path\*.*") do if [%~xa]==[.png] ren "%~a" "p-%~Na%~Xa"

Batch Script

SET "Src=C:\path"
SET "Str=p-"
for %%a in ("%Src%\*.*") do if [%%~xa]==[.png] ren "%%~a" "%Str%%%~Na%%~Xa"

FOR

  • Variable Substitutions (FOR /?)

    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 (")
    %~nI        - expands %I to a file name only
    %~xI        - expands %I to a file extension only
