Question

This seens to be a non frequent topic because I can´t find any reference of this.

Digital Certificates are stored in stores.

As you can see here…

How do I programmatically remove a certificate in Trusted Root Certification Authorities?

Where are stored the personal digital certificate?
The store name is My as we can see here:

http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.storename.aspx

But I need to find the location of the file itself to manipulate the certificate programatically.

Edit

I am also trying to print my cert name and path this way but I get nothing printed:

X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
X509Certificate2Collection storecollection = 
      (X509Certificate2Collection)store.Certificates;

Console.WriteLine("Store name: {0}", store.Name);
Console.WriteLine("Store location: {0}", store.Location);
foreach (X509Certificate2 x509 in storecollection)
{
  Console.WriteLine("certificate name: {0}",x509.Subject);
}

Answer 1

There are no physical files for individual certificates as far as I know.

On second question: you are missing Open call like store.Open(OpenFlags.ReadWrite);. See complete sample on MSDN X509Store.
