k_EUGCRead_ContinueReading
Keeps the file handle open. Use this when using UGCRead to seek to different parts of the file. When you are done seeking around the file, make a final call with k_EUGCRead_Close to close it.

k_EUGCRead_ContinueReadingUntilFinished
Keeps the file handle open unless the last byte is read. You can use this when reading large files (over 100MB) in sequential chunks. If the last byte is read, this will behave the same as k_EUGCRead_Close. Otherwise, it behaves the same as k_EUGCRead_ContinueReading. This value maintains the same behavior as before the EUGCReadAction parameter was introduced.
