DF file extension - Lightscape parameters

What is df file? How to open df files?

File extension df is mainly related to Lightscape Visualization System. A DF is a format used with the LVS version 3.2 to store the value of various parameters used by the system to control units, display modes, simulation parameters, search paths, etc.

Parameters files are human readable ASCII files, consisting of a sequence of lines. Lines can be any arbitrary length and must be terminated by either a carriage-return, line-feed sequence or simply a line-feed character.

This df file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
