Why, I wonder? Here is the problem: there is not such concept as "open a folder". This nothing but a UI metaphor. Even the notion of "folder" is a UI metaphor, there are only "directories". Detecting when a file is open (for, example, for copying) is in principle possible, but not easy...

mmmm , ok what I mean Is that any way to attatch action /event handller to that event ---> (Accessing specific Directory without my application)
in any level of programming languages or using batch files or by providing un breakable security rights on that folder ??

What is the purpose of a folder whose contents are deleted when access is attempted?
For example I could prevent theft by blowing up my house whenever someone enters. Does that sound logical?

If so then what is the use of that folder ;)

this is more related to network and security rather than the programming. try to give permisiion on that folder using security tab in the property. you can even use some third party tools like folder lock or filemananger or something for this purpose. you can also hide that folder if you do not wish others to open that folder.

Exactly

Ok thank you all for attention , I will try to clarefy the reason of delete file if some one try to access it : the reson of that is : currently I am working on Encryption application and I cant finde any way to manipulate large files and decrypt it on fly , I have to write the decrypted file some where in HDD Folder so I need to secure this Decrypted file by destroy it if some one try to copy it.

So you want to secure a file, not a folder.

Just set restrictive permissions to the file upon creation. Then only the user account that runs the decryption process and root/administrator can access the file.

yes exactly

That is an odd request. If no one else is supposed to access it, and you can afford to lose it, then why store it in a file in the first place? Just keep it in memory while your application is running.

OTOH, if you need to persistently story information, is it such a good idea to erase it based on an assumption that the data may be compromised?

Also, you should be aware that virus scanners and other services will try to access these files and directories. Blocking them will turn the directory into a safe haven for viruses and malware.

That in turn may cause security programs to rate your application as suspicious and potentially dangerous. Wouldn't that be embarassing for an application that is supposed to be extra secure?

How to keep it in memory ? and yes I think all right with you about Anti viruses , so...

After reading through the comments, the question should be updated.

This answer is Windows specific.

You can create a temporary file with exclusive read and exclusive write access AND set the file to be deleted when closed by your application.

See this link:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx[^]

Use zero for share mode (exclusive). Include FILE_FLAG_DELETE_ON_CLOSE for the flags parameter.

Leave the file open while your application is running. Just before you close the file, wipe the file contents.

This isn't 100% but covers most cases. If the device is powered off while the file exists, the data is still there.

A better solution (though not your original question) would be to decrypt only the portions needed and retain them in memory.
