On Library Creator, an error (Error occurred while writing library file. Error Code: E-04) is displayed and I cannot create a library.

1) There may not be enough free space on the USB storage device. Please check how much free space is available. In this situation, delete files from the USB memory device or USB hard disk to increase the amount of available free space prior to creating a library.

2) If you are using a USB storage device that has a lock function, the write lock may not be released. DISConnect the USB storage device from your PC, unlock the write protection and then you can use the device.
