Bad mysqldump backup file?

[xmagic_world]

I want to try use mysqldump to backup my database, this is what i used:
mysqldump" -u UserName -pPassword -B DBname>c:\backup.sql

the file creates fine, the problem is when I load the file into mysql Administrator 1.0.20 retore function and click "Analyze Backup File Content", it stops after around 3344 bytes processed. total bytes is more than 30000.

Anyone have an idea what might be the problem?
I am running windows xp professional and DB server 4.1.11

Thanks in advance
