What are these files?

[David Hite <dhite@mitre.org>]

I have two files that I can't erase from my 755CX. One is called 
"ea data. sf" and the other is called "wp root. sf". Yes, there are 
spaces in the names. Are these OS2 files? I tried to erase OS2 from 
my system, but I'm thinking these files may not have gotten erased. 
The first one occupies almost 7 megabytes, so I'd like to get rid of 
it. When I try to delete it, file manager says 
"Cannot delete ea_data._sf: Cannot find file". 
Anybody know how to get rid of these files?
