Open TLC File
A TLC file extension is a logo created with The Logo Creator, that's where its acronym comes from.
The Logo Creator is a graphic program designed to create and edit logos, developed by an independent company named Laughingbird Software.
The TLC file typically contains vector graphics and text, and can also include textures, 2D and 3D effects, and a transparent or colored background.
For this reason, a TLC file is considered a vector image file, however, as it is a proprietary format, it is not recommended for use in software other than The Logo Creator.
