File Extension Database

Open CTB File

CTB extension files have records, to date, of two different applications, namely:

AutoCAD

In this first case, a CTB file is a file used by AutoCAD, a CAD program used for 2D and 3D drawing.

AutoCAD is a commercial computer-aided drafting and design software application.

Developed and marketed by Autodesk, AutoCAD is a desktop application that runs on computers with internal graphics drivers.

AutoCAD has evolved over time and has expanded its scope to cover large areas of design.

The CTB extension file contains color-based plot styles, or color mappings to object layers, and is used to attach color and display settings to design objects.

CTB files are a bit old, however they can be superseded by the newer STB format, which abstracts layer color-based properties to object-based properties.

Many companies continue to use CTB files instead of STB files due to the cost of training staff and updating existing CAD designs.

CTB files and STB files cannot both be used within the same CAD design.

In all cases, CTB files can be converted to STB files using AutoCAD.

Cherrytree

A CTB file is a document created by Cherrytree, a note-taking application.

Cherrytree is basically a hierarchical note taking application, featuring rich text and syntax highlighting, storing data in a single xml or sqlite file.

Stores document data in SQLite format, which can include text, tables, images, objects, and document settings.

Password protected CTB files are saved as CTX files.

Users typically save Cherrytree documents as CTB or CTX files.

However, they can also save documents in XML format as CTD files.

CTD and CTZ files are useful for saving smaller documents than CTB and CTX files.

Cherrytree is developed by Giuspen, a Giuseppe Penone portmanteau.
