To be able to work with the Windows Explorer we need to know the terminology with which it works so that handling it will be easier.

A byte is the smallest unit of information. It is used to measure the size of our documents.

A kilobyte (Kb) is 1024 bytes, a Megabyte (Mb) is 1024 Kb, a Gigabyte is 1024 Mb

A File is a group of bytes. For example a text document is a file, a drawing is a file, etc.

Types of Files. There are different types of files depending on the type of information they contain. There are image files, program files, text files, music files, etc. To distinguish the type of information that they contain, the files are assigned a type of file or document. When the files are Word documents, for example, they are .doc.

Names of files. The name can have up to 255 characters, it can contain letters, numbers, blank spaces and special characters like dashes, underlines, etc., but there is a group that cannot be used ( ", ? , \, >, <, | ).

Folder. The folders are used to classify the files in our computer. The folders receive a name just like the files. We suggest that the folders, as well as files, be given names that are as descriptive as possible. A folder can contain files or other folders.

The folders are also known as directories.

In the Explorador the folders are represented by a yellow folder.

A Unit is like a folder but it encompasses much more information. The units are imaginary divisions that we make in our computer to access information easily.

The units that we have in our computer usually have the name of a letter from the alphabet.

The floppy drives usually receive the letters A, B.

The hard disks and the CD-Rom receive correlated letters.

In this image one can appreciate that there are 4 units; the disk units are represented by a , with the units of the disk drives the first represents the floppy drive (A:) then the DVD drive (F:) and the CD-Rom recorder (G:).
