If you've moved the file and the program needs it to start - then the program won't be able to start because it can't find that file. But, without more specifics it's difficult to tell the exact reason for it.

In a word - NO.
The power of accurate observation is commonly called cynicism by those who haven't got it.

Budapest is right.

Files are always identified by name - if a program needs a file it requests it by that name. But a heirarchical (tree style) filing system like modern computers use can have files with the same name in more than one location. So to be sure of getting the exact file the program needs, most programmers will write the program to look only where that file is supposed to be. Otherwise it might find a file with the same name somewhere else on the system, and it could be the wrong file and crash the program. If you move the file, the program looks only in the expected location, and fails to find it.

If a program requests a file only by its name without specifying a location, the operating system will look in a limited number of likely locations (known as the search path). But it won't go searching the whole computer. Programs mostly look after their own files, and only inform the operating system of what is necessary to allow the program to function correctly. An operating system that knew the purpose of every individual file on a system, which programs used them in what way, and tracked any changes made to that system so it could always find their files for them, would be incredibly cumbersome.

Maybe because you attempted to move the programs?

Give at least 2 specific instances of what you are referring to, please.

The location of the files is determined by the installer. If you customize the installation (ie - install it to another drive) then you'll have files installed on 2 drives. The installer manages this by adding stuff to your registry to keep track of it.
