CLD File Extension

Have a problem opening a .CLD file? We collect information about file formats and can explain what CLD files are. Additionally we recommend software suitable for opening or converting such files.

What is the .CLD file type?

Most frequently, the .cld extension is used by Canon's CD-LabelPrint tool, denoting the CD-LabelPrint Document (CLD) file type and format. CD-LabelPrint is the name of a proprietary Canon's software (Microsoft Windows only) bundled with Canon desktop printers (mainly, ink-jet). To run, CD-LabelPrint requires the presence of a compatible Canon printer.

A .cld file is a CD/DVD label project saved to a file. With CLD label project files, it is possible to design, save, and print out custom CD/DVD labels, either on paper or directly on optical disks. CLD disk labels use a proprietary file format and can be opened with CD-LabelPrint only. The CLD file type is automatically registered in the system upon installation of the CD-LabelPrint software.

With Microsoft Flight Simulator (also referred to as FS or FSX) and Microsoft ESP SDK (a commercial visual simulation platform), the .cld extension comes in association with the Flightsim Cloud (.cld) file type and format. CLD files contain modeled shapes of different types of clouds that are rendered to create a realistic skyline during simulation. In ESP SDK, .cld cloud files are placed into the "ESP\Weather\clouds" directory.

ClamAV, an open-source (GPL license) anti-virus system for Unix, and its derivative Immunet 3.0 for Microsoft Windows, use the .cld extension to denote their uncompressed virus definitions database files (.cld). With ClamAV, virus definitions are updated by downloading compressed definitions packages (.cvd), unpacking, and replacing the previous .cld files. There are generally two .cld files: "daily.cld" and "main.cld." On Unix-style OS'es (GNU/Linux and others), .cld files are located in the "/var/lib/clamav/" directory.

Standing for 'cloud,' the .cld extension can also mark generic 3D point could files. A point cloud file (.cld) is a formatted list of three-dimensional point coordinates obtained as a result of 3D scanning of a physical object's surface. Point clouds are typically used to re-create high-definition 3D models (also, by conversion into polygonal meshes). Import of generic .cld files may be supported by various 3D modeling tools.

In relation to Zandronum, an open implementation of the cult ID Software's Doom and Doom-like games with massive enhancements and add-ons, the .cld extension is used to identify demo sequence files. A Zandronum demo (.cld) is a recorded game session that can be displayed as a teaser on the game's startup.

With Project Amateras, an open-source Eclipse plugin for designing UML (Unified Modeling Language) class diagrams (AmaterasUML), the .cld extension is used to distinguish class diagram files (.cld). A .cld file is a UML representation of a class, with its methods, properties, and interrelations.

Apart from the above, the .cld extension also serves as a label for the Command Definition File (.cld) file type used with Hewlett-Packard OpenVMS products. A .cld file is a text file with command statements created for the OpenVMS Command Definition Utility (CDU).
