带空格的批处理路径变量-如何转义双引号？

Question

I'm setting a variable with this directory

C:\My dir\Sub dir\Folder with a lot of spaces\file.html

like this:

SET location="C:\My dir\Sub dir\Folder with a lot of spaces\file.html"

The problem is, when I echo %location% it comes with both double quotes. I've tried to remove using this:

set location=%location:"=\"%

But it does not work. I've searched a lot and I can't find an easy and simple solution. I'm using Windows 8.

Answer 1

An easy and simple solution is to store the path without the quotes, like this:

SET "location=C:\My dir\Sub dir\Folder with a lot of spaces\file.html"

This way the value will be stored with no quotes and the SET statement will still be protected from the effect of certain special characters. You will then either enclose %location% in quotes or omit the quotes as required. For instance, if you are using the value as an argument of some command, you will likely need to put the quotes around it:

somecommand  …
…

And if you just need to output the path, the quotes may be unnecessary – and it's easy to leave them out:

ECHO Location: 
…

Note that if the path has characters with special meaning, like & , ECHOing the path without the quotes would cause such characters to be interpreted in % evaluation. To avoid that, you could temporarily enable and use delayed expansion:

SETLOCAL EnableDelayedExpansion
ECHO Location: 
ENDLOCAL
…

Answer 2

使用set "location=C:\\My dir\\Sub dir\\Folder with a lot of spaces\\file.html"来保留空格，但不要使用双引号。

Answer 3

Don't use quotes in Set .

Later when you use that variable you include quotes around it eg

type "%location%"

Also this removes quotes

set location=%location:"=%

Yours I think replaces quotes with a backslash and a quote, not very useful.

Why even put it into a variable?
