.IEC File Extension

The iec file extension is associated with the Microsoft HTML Converter.

The iec file is renamed cnv file.

Microsoft HTML Converter was a part of the Internet Explorer. Seems to be discontinued.

.IEC file format is deprecated and this file format is no longer supported.

Currently, .IEC file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.

How to open:

Try to use Internet Explorer to open this file type, or there is no way now how to open this file.

How to convert:

As far as we know, this .iec file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
