Drag And Drop

Drag and Drop functionality allows you to create more user-friendly interface. With this interface, instead of selecting a series of menu options, user can drag the object and drop on to the required object. For example, to print a document, user can drag the document and drop on the printer icon, which will get printed. Similarly, dragging and dropping the same document on a recycle bin will delete the document. Whether you wrote the code to provide drag-n-drop functionality or not, you are using this in your daily life. Simple, example would be the File Manager. What you do to copy files from one drive to another drive. You simply select the files and drag them to the target drive. That's all.

If you do drag and drop files from one directory to another which are on the same drive, Windows will move the files instead of copying. The solution to this problem is, press the Ctrl key and hold it down as you drag the files.

If you drag and drop files between directories under Windows '95, the files won't get copied, instead, Windows creates links to the files in the target directory. You need to copy and paste using the right mouse button menu.
