How do I rename all file in a folder using DOS command

I have a folder called c:\myFolder,
inside it have "file1", "file2" and "file3",
I wish to rename all files inside the folder with the suffix "_o",
so the result will be
"file1_o", "file2_o" and "file3_o",
How can I do so?

Hi william007,

From command line, type..

FOR %f IN (*.*) DO ren %f %f_n

If you are running it from Batch file, replace % by %%
