The CURSORFX - CursorFX Theme File is a file that functions as a mouse cursor editing program. This file incorporates effects, mouse graphics, and trails. It also contains mouse movement preferences and events. The CURSORFX - CursorFX Theme File contains PNG files designated for cursor images, the files also store the author and version metadata. This theme file is stored as a zipped file in order to compress the data and reserve file space. CursorFX files that only encompass effects are known as mouse effects packages, and can be accessed from the Effects list on the control panel.
CursorFX files that include only trails are known as mouse trail packages and these packages are accessible through the trails list on the control panel of the CursorFX program. As the successor to CursorXP, CursorFX can open CurXPTheme files; however once opened these files will have to be saved in the CursorFX format.
