"descript.ion" file spec?
提问by DVK
There appears to be a somewhat standard "descript.ion" file in Windows programs universe which provides meta data for all/some of the files in a given directory.
Windows 程序世界中似乎有一个标准的“descript.ion”文件，它为给定目录中的所有/部分文件提供元数据。
I know there are various programs which write this file (example: NewsBin, UseNet downloader) and read it (Example: "FAR", a file manager mimicking old Norton Commander).
我知道有多种程序可以编写此文件（例如：NewsBin、UseNet 下载器）并读取它（例如：“FAR”，一个模仿旧 Norton Commander 的文件管理器）。
I'm writing my own file indexer, and would like to add the ability to parse and use the info from "descript.ion" files.
我正在编写自己的文件索引器，并希望添加解析和使用“descript.ion”文件信息的能力。
The problem I have is that I have not been able to find an actual spec for the file, despine much googling.
我遇到的问题是我无法找到该文件的实际规范，因此无法进行大量的谷歌搜索。
I reverse engineered it as best I could, but I'm not certain whether I captured 100% of the possible details, so I figured I'd ask SO.
我尽我所能对其进行了逆向工程，但我不确定我是否捕获了 100% 的可能细节，所以我想我会问。
Here are example lines from the file:
以下是文件中的示例行：
"Rus Song1.mp3" SovietMus 1/2, [email protected], Fri Aug 08 00:46:27 2008
RusSong2.mp3 SovietMus 2/2, [email protected], Fri Aug 08 01:46:22 2008
As it seems the structure is:
看起来结构是：
First "token" is a file name.
If the token starts with any letter but double quote, the token ends at the first
spacecharacter.If the token starts with the double quote, the end of token is the following double quote
Not sure what happens if filename contains a double quote, IIRC it's illegal in Windows filesystems, so escaping the quote may be a moot question)
Last token (end of line to the very last comma moving backwards) is a timestamp.
Second to last token (the very last comma to second-to-last comma moving backwards) is the name of the poster from the Usenet newsgroup. I'm not quite sure what happens in generic format since the only descript.ion files I saw were from NewsBin that is obviously Usenet centric.
Everything in between is a description, in NewsBin's case coming from post's subject.
第一个“令牌”是文件名。
如果标记以除双引号以外的任何字母开头，则标记以第一个
space字符结束。如果令牌以双引号开头，则令牌的结尾是以下双引号
不确定如果文件名包含双引号会发生什么，IIRC 在 Windows 文件系统中这是非法的，所以转义引号可能是一个没有实际意义的问题）
最后一个标记（最后一个逗号的行尾向后移动）是一个时间戳。
倒数第二个标记（倒数第二个逗号的最后一个逗号向后移动）是来自 Usenet 新闻组的发布者的名称。我不太确定通用格式会发生什么，因为我看到的唯一 descript.ion 文件来自 NewsBin，显然以 Usenet 为中心。
中间的所有内容都是描述，在 NewsBin 的案例中来自帖子的主题。
QUESTIONs:
问题：
Does anyone know of a bit more official "descript.ion" file spec/documentation? (or, at elast, have your own knowledge of those files and can verify my spec)
Does anyone know of any other programs that read or write this file?
有谁知道更官方的“descript.ion”文件规范/文档？（或者，至少，您对这些文件有自己的了解，并且可以验证我的规范）
有谁知道读取或写入此文件的任何其他程序？
Thanks!
谢谢！

The original usage of DESCRIPT.ION was to provide longer more descriptive names to 8.3 filenames; all it had was the shortname and a longer description. As you've found, others have co-opted the name with varying formats and usages. Frankly speaking, I don't think you'll find any specific commonality among the various usages.
DESCRIPT.ION 的最初用途是为 8.3 文件名提供更长的更具描述性的名称；它所拥有的只是短名称和更长的描述。正如您所发现的，其他人已经选择了具有不同格式和用法的名称。坦率地说，我认为您不会在各种用法之间找到任何特定的共性。

The description files on my system are from Total Commander as well. They follow the basic spec mentioned in the other answers:
我系统上的描述文件也来自 Total Commander。他们遵循其他答案中提到的基本规范：
Filename Text I typed to describe the file
"Long filename" Some text
Each line ends in a normal Windows line break.
每行都以正常的 Windows 换行符结尾。
In addition, the program stores multi-line comments as follows:
另外，程序存储多行注释如下：
Filename This is the first line\nSecond line\nLast line\x04\xc2
Here, I mean that the descript.ion file contains a backslash and a letter 'n' where I typed a line break, and two special characters 04 C2at the end of the comment. In addition, the line is ended by a Windows line break 0D 0A.
在这里，我的意思是 descript.ion 文件包含一个反斜杠和一个字母“n”，我在其中输入了一个换行符，以及04 C2注释末尾的两个特殊字符。此外，该行以 Windows 换行符结束0D 0A。
Apparently, the two extra characters at the end of the line signal the end of a multiline comment. If I remove them, the comment is rendered as a single line in the GUI, and the '\n' sequences are displayed literally.
显然，行尾的两个额外字符表示多行注释的结束。如果我删除它们，注释将在 GUI 中呈现为一行，并且 '\n' 序列按字面显示。

Format is simple: FileName remainder of the line is a description of the file
格式很简单：FileName 行的其余部分是文件的描述

the answer above looks correct for me, just a addition:
上面的答案对我来说是正确的，只是补充：
from http://filext.com/file-extension/IONThe ION file type is primarily associated with '4DOS'. Note: Norton Utilities also uses 4DOS.
来自http://fileext.com/file-extension/IONION 文件类型主要与“4DOS”相关。注意：Norton Utilities 也使用 4DOS。

The descript.ionfile is extensively used in the file management utility "total commander", a shareware found in www.ghisler.com. From version 7.5 of TC, it can have length of 4096 bytes. I have been using it extensively to annotate my files without any issues. You may look up different user's experience at the total commander users forum.
该descript.ion文件广泛用于文件管理实用程序“总指挥官”，这是一个在 www.ghisler.com 上找到的共享软件。从 TC 的 7.5 版开始，它的长度可以为 4096 字节。我一直在广泛使用它来注释我的文件，没有任何问题。您可以在总指挥官用户论坛上查看不同的用户体验。
