Getting directory from PageFiles folder of EPiServer

I'm having some thoughts about how the EPiServer PageFiles system work. When I get a global file it's simple to get the correct directory, I just write: ``` var dir = VirtualPathHandler.Instance.GetDirectory("~/Global/myfolder/", true) ``` But when I want to get files from the PageFiles folder it gets tricky for me. The path in the EPi backoffice upload says it is `PageFiles/myfolder`, but this doesn't return any folders ``` var dir = VirtualPathHandler.Instance.GetDirectory("~/PageFiles/myfolder/", true) ``` Now I see that files are saved different for each page, one page has the path `/PageFiles/361/myfolder/` and another page has the path `/PageFiles/65/myfolder/`. All I want to do is be able to write ``` var dir = VirtualPathHandler.Instance.GetDirectory("~/PageFiles/myfolder/", true) ``` but to get any folder I have to write (for instance) ``` var dir = VirtualPathHandler.Instance.GetDirectory("~/PageFiles/65/myfolder/", true) ``` What is the correct way to get a PageFiles folder so I can access all files in it? BTW, this is EPiServer 6.0
