Not enough space available on storage (NAS)

Files cannot be copied to the FRITZ!Box's storage (NAS) although there is enough space available on the USB storage device connected to the FRITZ!Box.

When using the Windows Explorer or macOS Finder to copy files to the storage device or when copying files to http://fritz.nas, one of the following error messages is displayed:

  • Not enough space on FRITZ.NAS (\\fritz.box).
  • There is not enough space on the drive.
  • The operation can't be completed because the drive is full.
  • Copying was aborted. Please make sure that there is a connection, sufficient memory is available, and the storage medium is not write-protected.

Note:Some devices, such as windows computers, may display more storage capacity for FRITZ.NAS than is actually available. See our guide Incorrect storage capacity shown for USB storage device for further information on this topic.

1 USB storage device has a partition that is not supported

The FRITZ!Box supports USB storage devices with partitions of up to 4 terabytes. If data should be copied to a larger partition, the FRITZ!Box attempts to save it to its internal memory. However, this is only possible if the size of the files does not exceed the available storage space on the internal memory of the FRITZ!Box.

If you are using a USB storage device with partitions that are larger than 4 terabytes, reformat the USB storage device:

  1. Reformat the USB storage device and only create up to four partitions, each no larger than 4 terabytes and formatted with the file system NTFS, FAT/FAT32 or ext2.

    ATTENTION!Back up your data before reformatting your USB storage device because all of the data on it will be lost during this process. Refer to the manufacturer for information on the formatting procedure.

2 Copying files to the USB storage device

The main directory of FRITZ.NAS and the folders in the main directory (for example "images", "documents", "FRITZ") are located on the internal memory of the FRITZ!Box, which has limited storage capacity.

If you want to copy larger files to the FRITZ!Box's storage (NAS), make sure that you copy the files to the USB storage device connected to the FRITZ!Box:

  1. If you are using the Windows Explorer or macOS Finder, in the network folder "FRITZ.NAS" select the folder with the name of the USB storage device and copy the files to a directory on it (see Fig.).

  2. If you are using a web browser, click on the folder with the same name as the USB storage device and copy the files to a folder on it (see fig.).
