About the CUR file type:

Invalid file associations could be the result of underlying issues within your Windows PC. It is highly recommended to scan your PC for invalid registry entries, unused processes and other slowdown issues.

The CUR file extension is specifically associated with the cursor files utilized under the Microsoft Windows Operating System platform. Basically, this file represents either a static or animated images commonly deployed in relation to mouse pointers like in the case of the Arrow, Spinning Hourglass, or I-Bar. This file may also be a part of a customized desktop theme package meant to supplement the bundled cursors of the Operating System such as the Spinning Hourglass being turned into a Wristwatch. The CUR format file has similarities with the ICO file extension used for Windows icon files. The main difference between the two image formats is the use of identification byte along with the specification of specific hotspots contained within the header. Generally, the intent for the design and implementation of cursor files is to provide the user the exact position of the mouse pointer in relation to the display area of the computer monitor or any relative display device that is part of the input process of any computing system. Aside from indicating the mouse pointer position, the cursor can also show the exact position where the next character to be typed would be placed within a line of text.

In some instances, the CUR file extension is referred to as a caret which is based on its usage on older UNIX computer systems for indicating the text insertion point. In most cases, the Arrow Cursor is the default mouse pointer used for pointing to the various objects displayed on the user screen. The user has an option to use left-, right-, single-, or double-click an object referenced by the mouse pointer. In terms of presentations and Web browsers, certain programming functionalities allow objects to perform predetermined actions when the cursor moves over or points to it. These actions can be anywhere from changing the objects properties (display color and size) to launching a separate application in the background. The CUR file extension is also used by the system to project to the user a graphical representation of the type of action being done by the computer system like when the Arrow Cursor changes to the Spinning Hourglass to indicate data processing. There are also instances wherein the cursor would provide the user with an indication that the system is frozen.
