Windows Cursor Image (.CUR) File Formats

Have you ever wondered how that mouse cursor on your screen works? Well, it’s actually due to a file format called the Windows Cursor Image (.CUR) which stores information about the shape of the mouse cursor. In this blog post, we will dive into the technical details of .CUR file formats, including their purpose, advantages and disadvantages.

We will also explore some interesting facts about them and give examples of how .CUR files can be used in practical applications.

So if you are new to the world of computer graphics, or have simply been curious about how that mouse cursor functions all along, then read on!

What is an CUR File Extension?

An CUR file is a Windows Cursor Image file. These files are generally used to store custom mouse pointers, and are typically created by graphic designers or software developers.

CUR files are very similar to ICO files, which are used to store icons on Windows computers. Both CUR and ICO files can be opened with a variety of graphics editing programs, such as Photoshop or GIMP.

CUR files usually have a .cur file extension, but they can also be saved with a .ico extension. When saving a CUR file as an ICO file, it’s important to remember to select the “Create ICO” option in the graphics editor’s Export menu.

Applications of CUR Files

CUR files can be used in a variety of ways, depending on their intended purpose. For example, they may be used to store images for use as mouse pointers, or to provide animated effects when a user interacts with an application.

Additionally, CUR files may also be used to store static images that can be displayed on a monitor or other display device.

Pros and Cons of CUR Files

When it comes to the Windows Cursor Image file format, there are both pros and cons that you should be aware of. Here are some of the most notable ones:

Pros of using CUR Files:

  • The CUR file format is relatively small in size, which makes it ideal for use in web applications where page load times are critical.
  • CUR files are also supported by a wide range of software programs and tools, so you shouldn’t have any trouble finding one that meets your needs.
  • Since CUR files are based on the Windows ICO file format, they offer good compatibility with other Microsoft products and services.

Cons of using CUR Files:

  • Although CUR files are small in size, they can still take up a fair amount of disk space when used in large quantities.
  • The Windows Cursor Image file format is not well suited for use with high-resolution images, so you may need to consider an alternative if this is a requirement for your project.

How To Open CUR Files?

CUR files are windows cursor image files that contain pointer data used for mouse input. These files can be opened with the Microsoft Cursor Editor, which is included with the Windows operating system, or with any other text editor.

To open a CUR file in the Microsoft Cursor Editor:

  1. Click Start and then type “cursor” into the search box.
  2. Click on “Microsoft Cursor Editor” from the list of results.
  3. In the “Open” dialog box that appears, select the CUR file you want to open and click “Open”.
  4. The file will now be open in the Microsoft Cursor Editor for editing.

How To Edit CUR Files?

When it comes to editing CUR files, there are a few things you need to know. First and foremost, CUR files are binary files, which means they can only be edited with a hex editor or a specialized cursor editor.

Secondly, the structure of a CUR file is quite complex, so you’ll need to have a good understanding of how cursors work before you attempt to edit one.

With that said, let’s take a look at how to edit a CUR file using a hex editor. For this example, we’ll be using HxD, which is a free hex editor for Windows.

Once you have HxD installed, open the program and then open your CUR file. You should see something like this:

The first thing you’ll need to do is find the header of the file. The header consists of four bytes, which are typically represented by “ffff”. In our example, the header starts at offset 0x0000 and ends at offset 0x0003.

Once you’ve found the header, you can start editing the various fields within it. The most important field is the “width” field, which is located at offset 0x0002. This field controls the width of the cursor in pixels.

For example, if we change the value from “64” to “32”, we’ll be reducing the width of our cursor by half:

Some Common Issues While Opening CUR File Extensions

If you’re having trouble opening a CUR file, it’s likely because you don’t have the right software application installed on your computer. CUR files can be opened with several programs, including Microsoft Paint, GIMP, Adobe Photoshop, and CorelDRAW.

If you try to open a CUR file with another program that isn’t listed above, you’ll probably see an error message or some other indication that the file can’t be opened.

If this happens, check to see if there’s an updated version of the program you’re using or if there’s a different program that can open CUR files.

File Extension Similar To CUR

There are many different file formats for images, and each one has its own specific purpose. The Windows Cursor Image (.CUR) file format is used for storing images that are used as cursors in the Windows operating system. These files are typically small in size and contain a limited number of colors.

The .CUR file format is similar to other image file formats, such as .BMP or .GIF. However, there are some important differences that you should be aware of.

For example, .CUR files can only be used as cursors in Windows. If you try to use them in another type of program, they may not work correctly.

In addition, .CUR files are usually saved in a compressed format. This means that they take up less space on your hard drive and load faster when you’re using them as cursors.

However, it also means that they may not look as good when viewed in an image editor.

Contact an IT Expert If You Still Can’t Open Your CUR File

If you still can’t open your CUR file, contact an IT expert for help. They will be able to help you determine why the file won’t open and how to fix the issue. In some cases, they may even be able to provide you with a software program that will allow you to open the file.

My Final Thoughts on (.CUR) File Formats

When it comes to Windows cursor image file formats, there are three main things that you need to know. First, there are two different types of files that you can use – ICO and CUR. Second, each type of file has its own advantages and disadvantages.

And finally, you need to decide which format is right for you based on your needs.

If you’re looking for a more in-depth explanation of each file format, check out our blog post on the topic. But if you just want a quick overview, here’s what you need to know:

ICO files are best for creating static cursor images. They’re simple to create and don’t require any special software. However, they’re not as flexible as CUR files and can’t be used for animated cursors.

CUR files are ideal for creating animated cursors. They’re more complex than ICO files and require special software to create them. But they offer much more flexibility when it comes to animation and can even be used for create interactive cursors.

Now that you know the basics of Windows cursor image file formats, it’s time to decide which one is right for you. If you need a static cursor image, ICO is the way to go.

If you want an animated cursor, CUR is the better option. And if you’re not sure which format is right for your project, feel free to experiment with both – there’s no wrong answer here!
