You can compress files in special folders that use compressing software to decrease the size of the files they contain. Compressed folders are useful for reducing the file size of one or more large files, thus freeing disk space and reducing the time it takes to transfer files to another computer over the Internet or network. A compressed folder is denoted by a zippered folder icon. You can compress one or more files in a compressed folder by simply dragging them onto the compressed folder icon. When a file is compressed, a copy is used in the compression, and the original remains intact. You can uncompress, or extract, a file from the compressed folder and open it as you normally would, or you can open a file directly from the compressed folder by double-clicking the Compressed File icon. When you open a file directly, Windows extracts the file when it opens and compresses it again when it closes.
Compress Files and Folders

Right-click one of the selected items, point to Send To, and then click Compressed (Zipped) Folder.
You can also compress file attributes in a folder. Right-click the folder, click Properties, click the General tab, click Advanced, select the Compress contents to save disk space check box, and then click OK twice.
