What Is a CUR File?

Using Windows Cursor Files

A file with the CUR file extension is a static Windows Cursor file. They're still images that are identical to .ICO (Icon) files in every way aside from the different extension. Animated cursor files have the .ANI extension instead.

Different cursor files are seen in the Windows operating system when the mouse pointer is doing certain tasks, like as a capital "i" when positioned over text or as an hourglass when something's loading.

Both animated and static cursor files can be found in the %SystemRoot%\Cursors\ folder in Windows.

How to Open a CUR File

Custom CUR files that you want Windows to use can be imported through the Mouse Control Panel applet. This Control Panel command line command opens this, too:

CUR files in Windows 10

If you want to see what the CUR file looks like as an image and not use it in Windows as a cursor, open the CUR file with Inkscape, ACDSee products, or Axialis CursorWorkshop—other graphics programs may work as well.

RealWorld Cursor Editor is free software that can edit CUR files and create new ones from other image file formats.

If you find that an application on your computer tries to open the CUR file but it's the wrong application or you'd rather have another installed program open CUR files, learn how to change the default program for a specific file extension in Windows.

How to Convert a CUR File

The best way to convert a CUR file is to use the RealWorld Cursor Editor program mentioned above, or the free online CUR converter at Convertio. Some of the file formats you can convert a CUR file to include PNG, ICO, GIF, JPG, and BMP.

Still Can't Open the File?

If your file isn't opening like it should as described above, double-check that you're reading the file extension correctly and not confusing a different file for one that ends with CUR.

The CUR file extension looks similar to CSR, CUE (Cue Sheet), CUS (AutoCAD Custom Dictionary), and CUB (Analysis Services Cube), but none of them are related to cursors.
