Can one exclude obfuscated files from PHP Explorer?

I have a PHP project, which partly consists of files that were obfuscated
(and/or precompiled?) using ZendGuard.
In PHP explorer these files are all marked with a red X.

Can one somehow exclude selected subdirectories from PHP explorer so that
one doesn't get all these "problems" displayed?
I am seeking for something similar to Java projects, where one has the
option to exclude (i.e. ignore) specific files in the source-tree. Does the
PHP plugin also offer such a capability? If so: how/where?

Cheers,
Michael
