File Extension DEC

File type: ArcView UNIX Hyperhelp Supporting File

About the DEC file type:

If Windows cannot find the appropriate program associated with .DEC files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The DEC file extension represents the HyperHelp Support file utilized by the ArcView application exclusively for the UNIX Operating System and similar platforms. The deployment of this file type is normally accompanied by the DTD and CAT file formats which are also classified as HyperHelp support files. The DEC file format supports the GIS functionality of ArcView, a general term applied to the different techniques of utilizing spatial data including the performance of spatial analysis. This technology is commonly used in relation to the handling of digitized maps and map layers. The HyperHelp function supported by the DEC file extension is basically a technology that allows software developers to incorporate context sensitive online help facilities for UNIX based programs using hypertext language. This file supports the RTF (Rich Text Format), bitmap, and project files similar to those used in the Microsoft Windows Operating System Help Files which was introduced from the Windows 3.1 version up to the latest Windows Vista platform.

The DEC file extension also extends support to majority of the mainstream text authoring utilities and tools in the market which includes ASCII text editors, SGML (Standard Generalized Markup Language) editors, FrameMaker, Interleaf, Lotus Word Pro, WordPerfect, and Microsoft Word among others. This standard relies on the context sensitive technology that incorporates a GUI (Graphical User Interface) for the topic contents including a fast index search engine capable of accomplishing the task in less than a second compared to approximately 30 seconds in earlier versions. This improved functionality was implemented by Microsoft under the Windows 95 Help files. Other application improvements incorporated into the HyperHelp technology includes the usage of the training cards feature that allows a two-way communication between the association program and the actual help files including the monitoring of authorable and depressable program buttons. It also takes advantage of the context sensitive menu from the functionality of the right mouse button which can display a pop-up menu and utilize a zoom feature. This provides the user the ability of selecting text from the main window which can be pasted or copied to another application's window by using API features to deliver an automated and interactive support system.
