冒号/星号作为文件名分隔符? [英] Colon/Asterisk as a filename delimiter?

问题描述

我正在寻找一个使用文件名定界符的字符(我将多个文件名存储在纯文本字符串中). Windows似乎不允许在文件名中使用:，?，*，<，>，"，|，/和\.显然，不能使用\和/，因为它们表示路径中的某些内容.有什么理由不应该使用其中任何一个?我只是在想，与/或\相似，那些其他不允许使用的字符可能具有特殊含义，我不认为它们不会出现在路径名中.在其他7个字符中，为此目的使用的任何绝对安全或绝对不安全的东西吗?

I'm looking for a character to use a filename delimiter (I'm storing multiple filenames in a plaintext string). Windows seems not to allow :, ?, *, <, >, ", |, / and \ in filenames. Obviously, \ and / can't be used, since they mean something within a path. Is there any reason why any of those others shouldn't be used? I'm just thinking that, similar to / or \, those other disallowed characters may have special meaning that I shouldn't assume won't be in path names. Of those other 7 characters, are any definitely safe or definitely unsafe to use for this purpose?

推荐答案

字符:和"也在路径中使用.冒号是驱动器单元的定界符，当空格是文件夹或文件名的一部分时，会使用引号.

The characters : and " are also used in paths. Colon is the drive unit delimiter, and quotation marks are used when spaces are part of a folder or file name.

字符*和?在搜索文件时用作通配符.

The charactes * and ? are used as wildcards when searching for files.

字符<和>用于将应用程序的输入和输出重定向到文件或从文件重定向.

The characters < and > are used for redirecting an application's input and output to and from a file.

字符|用于将一个应用程序的输出管道传输到另一应用程序的输入.

The character | is used for piping output from one application into input of another application.

我将选择用于分隔文件名的管道字符.它没有在路径中使用，并且其形状具有自然的分离品质.

I would choose the pipe character for separating file names. It's not used in paths, and its shape has a natural separation quality to it.

另一种选择是在字符串中使用XML.开销很大，有些字符需要编码，但是优点是它可以处理任何字符，而且格式易于解释且定义明确.

An alternative could be to use XML in the string. There is a bit of overhead and some characters need encoding, but the advantage is that it can handle any characters and the format is self explanatory and well defined.
