4. File Mime Type
There will be various times, and most likely during file
uploads, that a file’s mime type will be checked. That can
be accomplished with the method getFileMimeType().

5. Mime Type Result
Results of getting the mime type of the file.

6. File Size - Perl
To get the size of a file, we could simply use php’s filesize()
function. Or we could use the outside language of perl to get
the file size for us. If you are on Windows, you can utilize a
method called getFileSize_NTFS().

13. Challenge!
This is an optional challenge to help you better
understand file management in ProdigyView.
1. Pick a directory you want to retrieve all the files and
folders in.
2. Read that directory in verbose mode into
PVFileManager::getFilesInDirectory().
3. If the file is a directory, make a link that opens the
directory. If the file is a file, read the contents of the file
in with PVFileManager::readFile().
4. Get the newest file that has been added
