Is there local file manipulation that\'s been done with JavaScript? I\'m looking for a solution that can be accomplished with no install footprint like requiring Adobe AIR.<
If you need access to the entire file system on the client, read/write files, watch folders for changes, start applications, encrypt or sign documents, etc. please have a look at JSFS.
It allows secure and unlimited access from your web page to computer resources on the client without using a browser plugin technology like AcitveX or Java Applet. However, a peace of software has to be installed too.
In order to work with JSFS you should have basic knowledge in Java and Java EE development (Servlets).
