column "Name" in localweb page (no replies)

Hi,
this isn't really a problem, this is a kind request.
I have some long php files name in my localweb dir.
So they come out truncated on the localweb page displaying the content of the dir,
(there are about 20chars then a '..>' is suffixed).
I need long names because sometimes I have to add class name, student name and so on...
Is it possible change the size of that column?
Is is possible increase the number of chars displayed in the 'Name' column?
Thanks.
