Files\Folder in single file.

[vijy]

I have developed a windows product which deals with conversion of files(PDF to XML/HTML/doc), which will create some folders and files in local for application use.Also i am maintaining mdb, and some customized configuration files for he conversion.

These folders and files not needed to the user.But the application needs the same.

So i thought of encrypting these folder and files in a single file.When application needed it has to decrypt the file and use it inside the application.

Is there any third party or dot net component to do this.

What kind of files are they exactly? Executables and databases need to be extracted to the hard drive first before you can use them. The user can still access them when they are extracted to the hard drive.

You can use DotNetZip (WinZip) to create a single file or create your own file archiver.

What objection do you have to the files being visible to the user? What application do you know of which seeks to hide working files away in this way?

Why do they need to be hidden?

Unless there is some reason that these files really need to be hidden then it makes no sense to do so as it will make your code more complex and slow down your programs execution. If files need to be hidden from an average user there are many simple ways to do so, for example simply setting the Attribute flag to hidden will do it for most users.

The folder contains a mdb files,html files.. am maintaining an ini file inside for the application purpose. That all user dont want to read. so i try to make it by encrypting the things.

That all user dont want to read.

So, what's the problem? Nobody's forcing anyone to read them. Applications always come with many files that are of no great interest to the user (just look at Visual Studio itself!) By all means encrypt individual files if you think there's a security issue but don't waste time and effort on trying to keep hidden what clearly does not need to be hidden!
