Had an unusual situation, where I was using nero to backup a large number of files (over 1000, all in the same folder).
I hate having this many files in 1 folder, but many customers let this happen.
Nero would think about it for an hour, an then give the error message: not enough quota is available to process this command
I’m not sure about nero 7, but this is very irritating behaviour.
I eventually decided to just split the files into sub-folders, just to complete a backup.
