您是否曾经查看过文件扩展名并想知道您到底在看什么？有数百种不同的文件扩展名，不可能全部跟踪。
例如，什么是OGG文件？它是从哪里来的，它是用来做什么的？简单地(Simply)说，OGG文件是两种文件类型之一：Ogg Vorbis 音频文件(Ogg Vorbis Audio File)或 Origin 图形文件。
Ogg Vorbis 压缩音频文件
.Ogg 扩展名是一种免费、开放的容器格式，最初由Xiph.org 基金会(Xiph.org Foundation)创建。该组织是一个非营利组织，它创建和维护各种多媒体格式和软件工具，使创作者和日常用户能够在不支付高昂费用的情况下使用多媒体。
Vorbis是最流行和最常见的.ogg文件类型，但还有许多其他类型。除了.ogg扩展名之外，您还可以看到 .ogv、.oga、.ogx、.ogm、.spx和.opus。
如果您觉得“Ogg”这个名字很奇怪，那是因为它源自一个叫做“ogging”的古老游戏术语。1988 年(1988 game Netrek)的游戏 Netrek是最早的在线多人游戏之一，“ogging”指的是对敌舰或基地的神风敢死队式攻击。.ogg 扩展名是为了向那段历史致敬。
就像神风敢死队攻击一样，OGG 项目(OGG Project)被认为是雄心勃勃的，由于当时计算机的强大功能并不完全可能。该格式的创建者试图突破界限。
作为另一个有趣的琐事，这个名字的“Vorbis”方面源于 Terr Pratchett 的书Small Gods中的一个角色。
打开 Ogg Vorbis 文件
OGG文件很常见。因此，大多数主要媒体播放(major media players)器都可以打开它们，包括VLC、Windows Media Player等等。您甚至可以通过Google Drive打开(Google Drive)OGG文件。但是，Apple本身并不支持OGG文件。如果你想在Apple(Apple)设备上打开一个，你需要下载一个兼容的第三方应用程序，比如VLC。
Opera 和Mozilla Firefox也支持OGG文件，无需单独的程序。只需(Simply)在浏览器中拖动或打开文件，即可收听其内容，而无需打开其他应用程序。
GPS设备也可以接受 OGG 文件。然而，这是最常用的音频映射。您不太可能使用GPS设备播放音乐，但一切皆有可能。也许你想听你的Tom Tom唱 Bowie 的“ Space Oddity ” 。”
转换 Ogg Vorbis 文件
如果您需要将OGG文件切换为更普遍接受的文件，例如MP3或WAV文件，有几个简单的选项可供选择。
最简单的选项之一是像FileZigZag这样的(FileZigZag)在线转换器(online converter)。您无需下载任何内容，一次可以转换多个文件。缺点是您每天只能进行 10 次转化。
另一种选择是像Convertio。它完全可以在您的浏览器中运行，但也有一个Chrome扩展程序可用于轻松转换。转换次数似乎没有每日限制，但最大文件大小上限为 100 MB。
原点图文件
一种不太常见的OGG文件类型是 Origin Graph。什么是原始图 OGG(Origin Graph OGG)文件？这是由OriginLab Corporation创建的(OriginLab Corporation)数据分析工具和图形应用程序，最常被科学家和工程师使用。它创建显示各种类型数据的图表。
打开Origin Graph文件的唯一方法是通过Origin和Origin Viewer。Origin只能通过Windows 使用(Windows)，但Origin Viewer是Windows和Mac用户都可以使用的免费替代品。
如果您希望将Origin Graph文件转换为其他文件，Origin程序通过打开图表并选择File > Save Template As来实现这一点。选择要保存图形的文件类型，瞧！
在最近的Origin迭代中，文件以 .oggu 格式保存。这提供了对旧文件类型的性能升级，但它仍然允许用户打开OGG文件。
由于OGG(OGG)格式具有广泛的兼容性，开源软件的爱好者会喜欢它。它提供了一种有效的方式来访问和存储不占用内存的音频文件。
至于Origin Graph文件，除非您在相关领域，否则您不太可能遇到它们。
What Is An OGG File?
Havе you ever lоoked at a file extension and wondered exactly what in the world you were looking at? With hundreds of different file extensions, it’s impossible to keep track of them all.
For example, what is an OGG file? Where did it come from, and what is it used for? Simply put, an OGG file is one of two file types: either an Ogg Vorbis Audio File or an Origin graph file.
Ogg Vorbis Compressed Audio File
The .Ogg extension is a free, open container format originally created by the Xiph.org Foundation. This organization is a nonprofit group that creates and maintains various multimedia formats and software tools, giving creators and everyday users the ability to work with multimedia without paying exorbitant prices.
Vorbis is the most popular and common type of .ogg file, but there are numerous others. In addition to the .ogg extension, you may also see .ogv, .oga, .ogx, .ogm, .spx, and .opus.
If the name “Ogg” seems odd to you, it’s because it derives from an old gaming term called “ogging.” The 1988 game Netrek was one of the first online multiplayer games, and “ogging” referred to a kamikaze-style attack on an enemy ship or base. The .ogg extension is in homage to that history.
Like a kamikaze attack, the OGG Project was thought to be ambitious and not entirely possible due to the powers of computers at that time. The creators of the format sought to push the boundaries.
As an additional bit of interesting trivia, the “Vorbis” aspect of the name originates from a character in Terr Pratchett’s book Small Gods.
Opening An Ogg Vorbis File
OGG files are common. As a result, most major media players can open them, including VLC, Windows Media Player, and many more. You can even open an OGG file through Google Drive. However, Apple does not natively support OGG files. If you want to open one on an Apple device, you will need to download a compatible third-party application like VLC.
Opera and Mozilla Firefox also support OGG files without the need for a separate program. Simply drag or open the file in your browser and you can listen to its contents without opening another application.
OGG files can also be accepted by GPS devices. However, this is most commonly used whe audio mapping. It’s unlikely that you would ever use a GPS device to play music, but anything is possible. Maybe you want to hear your Tom Tom sing Bowie’s “Space Oddity.”
Converting Ogg Vorbis Files
If you need to switch an OGG file to something more universally acceptable, like an MP3 or WAV file, there are several easy options out there.
One of the easiest options is an online converter like FileZigZag. You don’t have to download anything and you can convert more than one file at once. The downside is you’re limited to 10 conversions per day.
Another option is something like Convertio. It works entirely in your browser, but there is also a Chrome extension available for easy conversions. There doesn’t seem to be a daily limit to the number of conversions, but the max file size is capped at 100 MB.
Origin Graph Files
A less common type of OGG file is an Origin Graph. What is an Origin Graph OGG file? This is a data analysis tool and graphing application created by OriginLab Corporation and used most often by scientiests and engineers. It creates graphs that display a variety of types of data.
The only way to open an Origin Graph file is through Origin and Origin Viewer. Origin is only available through Windows, but Origin Viewer is a free alternative that is available to both Windows and Mac users.
On the off-chance you want to convert an Origin Graph file to something else, the Origin program makes this possible by opening the graph and choosing File > Save Template As. Choose the file type you want to save the graph to and voila!
In more recent iterations of Origin, files are saved in the .oggu format. This offers a performance upgrade over the old file type, but it still allows users to open OGG files.
Fans of open-source software will appreciate the OGG format due to its broad range of compatibility. It provides an efficient way to access and store audio files that doesn’t hog memory.
As for Origin Graph files, unless you’re in a relevant field, you aren’t likely to encounter them.
