What is a GUL file?

GUL files mostly belong to JungUm Global. Overview:: GUL files appear in two main varieties. The majority are Hangeul (Korean) document files that use the Microsoft Compound file format. This structure allows different data streams, such as text, images, layout data, and hidden metadata, to be stored in one file. These files are produced by JungUm Global and are designed for Korean language documents.
Another set is composed of NASCA DRM protected files. These files incorporate digital rights management to restrict access and usually require special, authorized software to open and view the content.
Key points compiled by FilExt.com:

Microsoft Compound format: Allows multiple streams within a single file.

Hangeul document file: Primarily contains Korean language content with rich formatting.

NASCA DRM protection: Uses encryption that restricts file access without specific software.

FilExt.com notes: If you have a GUL file, first check whether it is a Hangeul document or a DRM protected file. For Hangeul documents, use software that supports Microsoft Compound files—often provided by JungUm Global. For DRM files, you will need the proper NASCA DRM application to view the content.

Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE").
