C# Programmatically Setting Permissions and Compressing a Folder (NTFS)

[steggun]

Hello,

I'm writing a C# windows form application and need some guidance on a couple
of issues.

First, my application needs to change the permissions on a folder. The
application creates a local group and I need to give that group Full Control
permissions to a folder on the file system. Would anyone know how to
accomplish this?

Next, my application also needs to programmatically set the properties of a
folder so that it's compressed. Would anyone know how to accomplish this?

Thanks!

When using V2 of the FCL you can use the FileSecurity class in the
System.Security.AccessControl namespace to change the access rights of a
filesystem object. The "compressed" FileAttribute of the DirectoryInfo class
can be used to set the compressed attribute of a folder. However, be aware
that you need to run as an administrator to be able to do this, which is a
bad idea, user applications should never run with administrative privileges.
Much better is to delegate this to an "administrative" application that
could be run as a COM+ server type application (check the
System.EnterpriseServices namespace), this application can run as
administrator while yours keep running with restricted privileges.
