I want to write a program that hide a file so that noone can see it in the directory (but not delete). And will unhide it when i need.
What technology if this i need to learn to do that?
Thanks

What OS, language do you plan on using....etc....etc...etc

You know that on any OS a hidden file can still be displayed. It just won't show by default.

I write for Windows.
i know what you means. But i want to know other tech. Because if we set the file's attribute is "hide", user can easily unhide if they choose folder option/and choose unhide in windows.
I mean that i will hide all time even user set view unhide file. And just my program can set unhide attribute to the file only.
