Depends on the file type, some, especially downloaded files and executables (.EXE and .COM) files are already compressed, so therefore won't be smaller when you zip them.
You can combine zip files into a single zip file, but it doesn't make the file size a smaller total.
When files containing large amounts of information are compressed or zipped, they are moved and forced into a smaller space to conserve memory and protect the file(s).
Compressed (zipped)
You can no longer view these files, but they will take up less space on your hard drive. If you want to view them again, just unzip it (pretty much the same way you zipped it). Compressing files is good for sending them to someone, or if you need more space on your hard drive. It gets smaller.

.rar
Usually; however some file formats (jpg and mp3 are good examples) are already compressed and zipping them will not generally compress the file much further.
Compressed files are often named colloquially after the software used to consolidate them. Common names include Rars, and Winzips for these file archives.
Although many files these days do come in zipped files it is extremely easy to unzip the files. One of the oldest and best known programs for doing this is a program called WinZip.
It is very easy to unzip files. Firstly you need to download the zipped file,and save it to your computer. You can download programs from cnet, which will allow you to automatically unzip compressed files.
A folder is a container that holds files. A zipped folder is a folder or a group of files that have been compressed by a special program such as WinZip. WinZip is a paid compression program. 7zip is a free file compression program.
