#31782 — Local filesystem.

I am writing a web application and I want to store some user data
on his local site, not on the server.
Is it possible ?
Is there a set of functions for manage the local filesystem ?
And if it is true, how can I do that ?
Thanks for any idea.

Yes.

Depends on the data.  How long have you searched (the Web) for a solution?

Incorrect.  It depends where and how the script is running.

Read <https://en.wikipedia.org/wiki/HTML_Application>.

A Web application should not be able to read/write the local filesystem
without explicit permission; but running an HTA in MSIE might be
considered as giving such permission.

See <https://en.wikipedia.org/wiki/Sandbox_(computer_security)> and
<https://en.wikipedia.org/wiki/Sandbox_(software_development)>.

Look at <http://wsh2.uw.hu/index.html> ff., as it might be useful to
you, some day.

A web application can do whatever it wants —if implimented improperly— however they will do what they are told to do perfectly most of the time.
If the web app is being served on his local machine you can write Javascript intended to be used on a specific platform i.e. macOS/Unix or any other operating system that exists and I don't care about. If it is being served via his server then it will more than likely have to be done with session/local storage and configured with key/pair values, JSON.parse and a whole lot of other stuff that could have been done using PHP and the FTP protocol.

Perhaps Web Storage will cover your needs:
