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:

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

Hope this helps anyone.

Don t do this  You re opening your machine to attacks  Instead run a local server  It s as easy as opening a shell terminal commandline and typing  cd path to files python -m SimpleHTTPServer   Then pointing your browser to  http   localhost 8000   If you find it s too slow consider this solution

As of this writing  in OS X  it will usually look like this    Applications Google Chrome app Contents MacOS Google Chrome  --allow-file-access-from-files   If you are a freak like me  and put your apps in   Applications  then it will be     Users yougohere Applications Google Chrome app Contents MacOS Google Chrome  --allow-file-access-from-files   If neither of those are working  then type chrome   version in your Chrome address bar  and it will tell you what  command line  invocation you should be using  Just add --allow-file-access-from-files to that

You may want to try Web Server for Chrome  which serves web pages from a local folder using HTTP  It s simple to use and would avoid the flag  which  as someone mentioned above  might make your file system vulnerable

Search for the path of your Chrome executable and then  on your cmd  try     gt   C  PathTo Chrome exe  --allow-file-access-from-files   Source  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     gt    chrome exe --allow-file-access-from-files

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   npm install -g http-server  Then simply run http-server in any of your project directories   Eg  d  my project gt  http-server  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   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 python -m SimpleHTTPServer in your project directory  and you can load your page on http   localhost 8000  In Python 3 the SimpleHTTPServer module has been merged into http server  so the new command is python3 -m http server   Easy  and no security risk of accidentally leaving your browser open vulnerable
