What is a ITT file?

Itt file extension has IconTweaker Theme file type, developed by Joost Verburg, which is associated with the "settings files" category.

IconTweaker is free software for changing standard Windows icons. Files created by this program are saved with the ITT extension. They store settings for a Windows theme, including an alternative mapping of theme icons. ITT files use XML formatting. IconTweaker allows users to replace all Windows icons, even My Computer, My Documents, Recycles bin, and folder icons. Files with this extension are usually bundled with multiple .ICO files or single .ICL file. Sometimes ITT files are packed in compressed .ITA files to make file sharing over the Internet a bit easier. The IconTweaker software has been retired with the release of Windows XP.
