## Description
Creates a `FolderItem` from the passed FSRef.
## Notes
The method takes a `MemoryBlock` of size 80 containing a Mac OS FSRef structure that can be obtained from various Carbon File Manager functions, usually using the `Declare` statement.
This will only work on macOS. On Windows and Linux it raises a `PlatformNotSupportedException`.
## Sample code
For purposes of illustration, this example creates a FolderItem from an internaly-generated `MemoryBlock` that contains a user-selected mp4 file.
``` xojo
Dim f As New FolderItem
Dim g As New FolderItem
f = GetOpenFolderItem("video/mp4") ' added using the File Types Editor
If f.MacFSRef <> Nil Then
g = f.CreateFromMacFSRef(f.MacFSRef)
MsgBox(g.NativePath)
Else
MsgBox("The MacFSRef was not created.")
End If
```
## Compatibility
All project types on all supported operating systems.
