FRITZ!Box 7430 – Service

Files contained in FRITZ!NAS cannot be played, edited or deleted

Files contained in FRITZ!NAS (http://fritz.nas) cannot be opened or played with the web browser or a different application. You also cannot edit or delete the files. When you attempt to play the files with a FRITZ!Fon, the message "The mediaserer is not responding correct" is displayed.

The names of the files correspond to the directory where they were originally saved on the computer (for example "C:\Users\Martin\Music\Pharrell_Williams_Happy.mp3").


  • The Internet Explorer was used to copy the files to http://fritz.nas and the browser modified them.

2 Deleting files from FRITZ!NAS

Delete the corrupted files from FRITZ!NAS:

  1. Remove the USB storage device from the FRITZ!Box and connect it to a computer.
  2. Use the computer to delete the corrupted files from the USB storage device.

    Important:If you also cannot delete the files with the computer, you must reformat the USB storage device. Since reformatting the USB storage device will delete all of the data on it, you should back up your data before reformatting it.
