The current folder is whichever folder you happen to be in at the time. So, for instance, you you open a command prompt and type in cd \, you will change to the root folder. The current folder will be the root folder.
What folder are the images you wish to capture the names of in? Let's assume the folder is called C:\Images. Open a command prompt and navigate to C:\Images to make it the current folder, then type in the command: for %x in (*.jpg *.gif *.png) do echo %x , >> out.csv This will create a file in the folder called out.csv. If you go into Windows Explorer and find that file and double-click on it, it will open in Excel and all of your image files will be listed there.
