What is OGM File Format?

The OGM (OGG Media) file format was developed as an independent extension of the OGG file format created by the Xiph.org Foundation. It was designed as a container for OGG Vorbis soundtracks, video and subtitles that can be used with DirectShow. It was never formally endorsed by the Xiph.org Foundation.

Characteristics and Uses

OGM File Format

The main problem with this file format is that there is almost no documentation except for the source code. Thus, most characteristics have to be deduced by reading the code.

Adding to it, there is no standard way to verify if a file is a valid OGM file, as this verification has not been defined by its creators.

One important difference of this file format is that OMG files can be of unlimited size as they are not indexed. This lack of indexation has been praised by some people and criticized by others.

OGM files are compressed using the Ogg Vorbis compressing technology. Vorbis is a free, open source project managed by the Xiph.org Foundation. As its website explains, it is a patent-free, professional audio encoding and streaming technology, created after plans by the Fraunhofer Society to implement licensing fees for the MP3 audio format.

The Xiph.org Foundation defines itself in its website as “a non-profit corporation, dedicated to protecting the foundations of Internet multimedia from control by private interests”. It also declares its main purpose as “to support and develop free, open protocols and software to serve the public, developer and business markets”.

Brief History

In 2002, as a result of the lack of video support in the OGG file format, the Xiph.org Foundation created the OGM file format. This file format embedded a video from Microsoft DirectShow into an Ogg-based framework.

However, later as the Matroska container file format provided a better option, the Xiph.org Foundation decided to drop its support for the OGM format and to discourage its use.

An important limitation of the OGM files is their incapacity to handle Unicode subtitles, creating problems with films in languages with different alphabets, such as Russian.

How to Use Image Files to Recover OGM Files

Image files are a bit-by-bit copy of an original digital drive. Thus, they are an exact copy that contains all information, including your deleted files.

It is a very good practice to perform your OGM file recovery from an image copy. In this manner, if you make a mistake, you won’t damage the original source, and you can repeat the OGM recovery on another image copy.

Disk Drill has the capability to create image files. Just click on the “Extras” menu, and you will find the corresponding option. Once your image is created, perform your OGM recovery from it, by selecting the image drive.
