c# - How do I get the security details for a long path?

Question

I am doing a file server migration and I'm writing a small C# app to help me map the user permissions so we can put them in user groups.

I'm currently using

Directory.GetAccessControl(path);

However it fails when it get to this 263 char file path.

Invalid name.
Parameter name: name

I get the same error when I use DirectoryInfo.GetAccessControl();

Is there a work around or alternative to this method?

Thanks!

One alternative is to use subst. From a command prompt, you can execute

subst X: "D:
eally really reallylong pathhat you can shorten"

Then perform your operations on the X: drive and the whole beginning section won't count against your 260-char limit.
