Hi,

I have some files in a folder which needs to be password protected using java. So i need to stop direct access from other users to open the folder but should be only accessible using the api.
This needs to be implemented in java only.

Please help me.

Thanks

What is the operating system you are talking about - is it Window, Unix?

On Unix system you can create folders and make them accessible only to the user
who created them. Then you could allow other people to access them through your Java
program and may require credentials to do so. In this way these folders
will become accessible only after authentication.
Of course Unix administartor will still have access to this data.

This is a java-centric discussion about password protected files:

This isn't practicably possible: access control to a file system is done at operating system level and therefore makes little sense for a cross-platform language like Java.

Consider instead using storage outside the file system, which of course you can implement in a platform-independent way
