Do something like the following to recursively clear readonly (and archive, etc.) for all directories and files within a specified parent directory.
private void ClearReadOnly(DirectoryInfo parentDirectory)
{
if(parentDirectory != null)
{
parentDirectory.Attributes = FileAttributes.Normal;
foreach (FileInfo fi in parentDirectory.GetFiles())
{
fi.Attributes = FileAttributes.Normal;
}
foreach (DirectoryInfo di in parentDirectory.GetDirectories())
{
ClearReadOnly(di);
}
}
}
You can therefore call this like so:
public void Main()
{
DirectoryInfo parentDirectoryInfo = new DirectoryInfo(@"c:\test");
ClearReadOnly(parentDirectoryInfo);
}
