For just one filename i would use the explorer.  
if there are more files to be renamed, I am not quite sure whether a search/replace on the pseudo variable filename works.  
If it does not:  
format a custom tag with the name e.g. "newfilename" with %\_filename%.  
replace all blanks in "newfilenmae" with nothing with a simple replace action.  
copy the value of newfilename into the pseudo tag %\_filename%.  
the FAQ  
[/t/967/1](https://community.mp3tag.de/t/967/1)  
shows you how to copy values from one tag to another.
