One theme of the GUI revolution is the ability to custimize your computer to the way you think and work. The tools we have talked about so far are great at dealing with the physical structure of files and directories on your disk, but the way your disk is organized may not be the way you want to think about your files. For example, most modern program install themselves, and put themselves in directories they create. If you don't like the way the program is stored on the disk, you could change it, but that would be a lot of work. Also, you may have all the word processor files in one directory, all the spreadsheets in another, and so on. This may be convenient sometimes, but you may want to organize things differently, by project, for example. You might have a project that uses some word processor files, some spreadsheet files, and some other programs. You might want to have copies of all these programs organized together. You might also want to have copies of common programs available in a number of ways. One solution would be to actually copy these files over through a file management system, but such a solution would be difficult, prone to errors, and tedious. Wouldn't it be great if there were some way you could make little shortcuts to programs and files that could be easily manipulated?
