File Extension OCX

File type: Object Linking and Embedding (OLE) Custom Control Files

About the OCX file type:

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

The .OCX file extension identifies Object Linking and Embedding (OLE) Custom Control Files (these days called ActiveX Control files). These files are associated with creating custom controls for applications running on Microsoft Windows systems. Files of this type do not need any special program since these are usually files that can be run by Windows by default.

Additional Information:
Be aware that these types of files may under certain circumstances be infected with trojans or viruses for this reason take extra attention when running such files.
