.TSZ File Extension

A TSZ file is a skin used by Cerulean Studios Trillian, an instant messaging (IM) program. It is used to change the appearance of Trillian's user interface. Current versions of Trillian no longer allow users to install TSZ files.

Trillian is a multiplatform IM application that is used by individuals and businesses. It allows users to connect to and chat across multiple IM services. Healthcare organizations, for example, use Trillian to conduct secure, intraorganizational chats.

In previous versions, Trillian allowed users to install skins that changed the program's appearance. These skins are saved in TSZ files. Each TSZ file is a Zip-compressed package that contains all the assets needed to alter Trillian's appearance. This includes .BMP, .PNG., and/or .JPG images and .XML files.

NOTE: Some Trillian skins are saved as normal .ZIP files.

Users can no longer install TSZ files in current versions of Trillian. In previous versions of Trillian, you could install a TSZ file by decompressing the file, placing the resulting folder in Trillium's Skins directory, and applying the skin from Trillian's Preferences menu.

If you want to view the assets a TSZ file contains, you can decompress it as you would any ZIP file. Note that you may have to first change the file's extension to .zip.
