Can you provide more information? The error message you have posted doesn't make sense to me for the following reasons:
Code: Select all
MOVE:/Multimedia: Read-only file system
* no source file path; no target file path
* /Multimedia doesn't make sense; macOS doesn't allow you to create folders in the / root folder; network shares would be mounted into /Volumes at the very least
* no space between :/ indicates that you didn't just copy & paste the error message verbatim; ideally you'll want to copy & paste the error message from the log verbatim

Can you copy & paste the complete log so that we can see the complete error message? Please read
How to Request Help on how to find and print the log.
