Compatibility Considerations
• With the new tree structure, you now see all files, including those in subfolders.
You might not be able to run the files you see in the subfolders. To run a file from a
subfolder, the subfolder must be on the search path or the subfolder must become the
current folder. In previous versions, you could only see files in the current folder, so
you could run every file you could see.
