There are two types of folders: • Container Folders, which can only hold or contain other folders (sub-folders). They are usually used for organizing the content. • Application Folders, which contain applications such as chat, files, images, calendar, HTML pages, and so on.
You can have both files and folders in other folders. Sometimes they are referred to as sub-folders to indicate that they are inside another one.
Easy - CD to the directory with the files and folders, and do: zip -r foo *
Be careful with hidden files. Some system files are hidden for a good reason. I will assume you use Windows : 1. Open Windows Explorer; 2. Click on Tools; 3. Click on Folder Options ..; 4. Click on View tab; 5. Click on Hidden files and folders; 6. Select Show hidden files and folders; 7. Click OK; 8. Delete the icon; 9. Set option back to Do not show hidden files and folders (for security reason if you are not the only one using the computer).

Complete folders cannot be sent directly through Gmail. Only files can be sent as attachments. You can compress it into a zip file and then can send it.
No, folders usually do not have file extensions, but they could have if you like. Usually only files have extensions, to indicate the contents of the file.
When a computer re-boots, it is turned off and then turned back on. It resets only certain folders while renews other ones. It is also a chance for the computer to update and renew files. Hope it helped, have a nice day. :)
The RAM, or, Random Access Memory. This is what your computer uses to move around small files. The RAM can be used to move larger files, but only portions at a time.
