    Changing all files with no extension in the folder using powershell


    I don't know how to change extensions of all files in my folder.

    All files don't have any extension and I dont know how to do it with powershell.

    How do I change it so all of them have extensions?

    :)

    File extension *.docx

    Hi Randy,

    To change the file extension when saving a document in Word 2013, you may follow the steps below:

    • Click on File; then, select Options from the list.
    • In the Word Options window, choose Save.
    • Under Save files in this format, select *.doc from the list.
    • Hit OK button to confirm and save the changes.

    If ever your Word 2013 application is not recognizing the changes you have made, you may restart the application; however, if the issue still persists, we suggest that you repair it. To do this, see this
    link.

    We would appreciate it if you could get back to us and provide us your feedback.

    Changing all files with no extension in the folder using powershell

    How to rename image files in a folder all to .jpg format

    Hi,

    Since you now only have the option to use the PowerShell to change file extensions by batch, here's an example of how you can use
    PowerShell in replacement of the Command Prompt:

    ie. Changing .png to .jpg.

    • Open the folder where you will change the file extensions by batch. (Note:
      This will change all the format of the files inside the folder.)
    • Click the File tab, then Open Windows PowerShell.
    • Type or copy this:

      Dir *.png | rename-item -newname { [io.path]::ChangeExtension($_.name, "jpg") }

      Note: Make sure that you change ".png" and ".jpg" to the file extensions based on your situation.
    • Press the Enter key from the keyboard.
    • Refresh the folder.

    Oh, by the way, have you noticed an option to open a Command Prompt
    from the File tab when you were on Step #2?

    We're just a post away should you have further queries.

    Regards.
