Search for the path of your Chrome executable and then, on your cmd, try :

<a href="http://www.chrome-allow-file-access-from-file.com/">Source</a>

EDIT :
As I see on your question, don't forget that Windows is a little bit similar to Unix, so when you type "chrome ...", cmd will search for Chrome in the PATH, but in general the Chrome folder isn't on the PATH. Also, you don't specify an extension for your executable... So if you move to Chrome's folder, this command will probably work too :

<pre><code>&gt; .\chrome.exe --allow-file-access-from-files

If neither of those are working, then type <code>chrome://version</code> in your Chrome address bar, and it will tell you what "command line" invocation you should be using. Just add <code>--allow-file-access-from-files</code> to that.

That flag is dangerous!! Leaves your file system open for access. Documents originating from anywhere, local or web, should not, by default, have any access to local file:/// resources.

Much better solution is to run a little http server locally.

--- For Windows ---

The easiest is to install http-server globally using node's package manager:

<code>npm install -g http-server</code>

Then simply run <code>http-server</code> in any of your project directories:

Eg. <code>d:\my_project&gt; http-server</code>

<pre><code>Starting up http-server, serving ./
Available on:
 http:169.254.116.232:8080
 http:192.168.88.1:8080
 http:192.168.0.7:8080
 http:127.0.0.1:8080
Hit CTRL-C to stop the server
</code></pre>

Or as prusswan suggested, you can also install Python under windows, and follow the instructions below. 

--- For Linux ---

Since Python is usually available in most linux distributions, just run <code>python -m SimpleHTTPServer</code> in your project directory, and you can load your page on <code>http://localhost:8000</code>

In Python 3 the <code>SimpleHTTPServer</code> module has been merged into <code>http.server</code>, so the new command is <code>python3 -m http.server</code>.

Easy, and no security risk of accidentally leaving your browser open vulnerable.

Depending on the file which will be put into filesystem, as long as that file is not a malware, then that would be safe.

But don't worry to write/read file(s) to File System directory, cause you can tighten that directory security (include it's inheritance) by give a proper access right and security restriction. eg: read/write/modify.

By default, File System, Local Storage, and Storage directory are located on "\Users[Current User]\AppData\Local\Google\Chrome\User Data\Default" directory.

However you can customize it by using "--user-data-dir" flag.

And this is a sample:

<pre><code>"C:\Program Files (x86)\Google\Application\chrome.exe" --user-data-dir="C:\Chrome_Data\OO7" --allow-file-access-from-files
</code></pre>
