File Type 2 PSP Custom Theme File
Category: Settings Files

A CTF file contains a custom theme used by Sony PlayStation Portable (PSP), a handheld gaming console. It stores custom theme settings and includes .BMP wallpaper and preview picture and .PNG icon that appear in the PSP interface. CTF files allow PSP users to create their own themes for their PSP devices.

CTF files can only be applied to a PSP if the device has the custom .PRX CXMB plugin installed. If it does not have the plugin installed, the PSP will not be able to load the theme.

CTF files may be used to transform multiple files with different structures into a consolidated format. This makes it possible to bulk load or migrate many files at once.
