Peerless is just asking what
Operating
System (OS) you are now using, meaning...
Windows, and what version of Windows ?
or
The same if you are using a Mac instead of a PC...
Also, we need to know what version of LimeWire you are now using and whether or not it is a new and 'fresh' install or a re-install or update of LimeWire...
After you say what you have for a computer it will be much easier for people here to be able to give you the simple instructions about how to learn to manage your Folders and Files...
Or, to help you if you have some actual problem with your system...
