How to install a zipped file

i have downloaded some drivers from clevo.com and have saved them to my documents. they appear as a compressed(zipped)folder. how do i install them!!

 

Unzip each and see what the file extension is.

if you can not right click the zipped file and choose "extract".

 

This is not true for XP. Windows XP included winzip but I guess after a lawsuit, they do not include it with Vista and Win 7. Since we don't know what OS the OP is running, I said this

based on the fact he might be able to extract without installing another program.

 

All versions of Windows from XP onwards will compress and extract files from to/from zip files without any other software assistance. In XP compression was Send to Compressed Folders, and extraction merely required a double click on the file.

Programs such as WinZIP are useful, but not essential.
