Setup Files Disk Space

I've been trying to clean up space on my C: drive to get my system back up to speed. Looking in my Program Files -- there are now SEVEN directories of some SmartFTP variety, totaling about 45MB (versions 1-3; that 45MB does NOT include any log storage)

I was wondering if I can ditch any of these or do I actually need to keep all of them?

SmartFTP
SmartFTP Client
SmartFTP Client 2.0
SmartFTP Client 2.0 Setup Files
SmartFTP Client 2.5 Setup Files
SmartFTP Client 3.0 Setup Files
