What is the .VCX File Extension?

.VCX File Extension Description:

Defined as a Visual Class Library, a file with the .vcx extension is a database file that contains references to different classes used in an application created by Microsoft Visual FoxPro. Initially, a .vcx file contains a table with lists of different classes along with their definition. To view the information in a VCX file, you may need to use the Class Viewer application bundled with FoxPro.

In terms used in Computer Science, a class is used in object-oriented programming used in related fields and methods in a certain programming language; in this case, Microsoft Visual FoxPro. Simply put, a class is a package that holds metadata (data description) that describes how a certain object will behave in that specific application. This will include access, editing, deleting, object behavior, and so on.

Classes are used to accelerate the runtime of certain applications by eliminating redundant source codes, and using call functions to retrieve them from external standalone file, including files with the .vcx extension.

Using Microsoft Visual FoxPro, a programmer can manipulate the table in the .vcx file using the USE command, with the same protocol as accessing database files (DBF). When a class is created and saved in a .vcx file extension, the first record is about the class definition, followed by the Reserved1 field in the table, which contains the word "Class" that tags the record as a class definition.

Other versions of VCX files are those used in images for many CD and DVD content. These kinds of .vcx files are usually around 30Kb to 32Kb in size and contain instructions on how to merge multiple files to produce the original executable file. Such a file extension that contains data merged by a .vcx file includes .cd1, .cd2, .cd3, and so on.
