Windows – batch find file extension


If I am iterating over each file using :

@echo off

FOR %%f IN (*\*.\**) DO (
    echo %%f

how could I print the extension of each file? I tried assigning %%f to a temporary variable, and then using the code : echo "%t:~-3%" to print but with no success.

Best Solution

The FOR command has several built-in switches that allow you to modify file names. Try the following:

@echo off
for %%i in (*.*) do echo "%%~xi"
