Remarks

This method is designed to handle the case where the user wishes to create a file in a folder with a given name when there is a possibility that the name is already taken. Using this method, it is possible to create files with names in the following format:
  • File.ext
  • File (1).ext
  • File (2).ext
  • ...
This method uses a binary search to find a unique file name, so it is suitable for situations where a large number of files will be created with the same file name, and the next unique file name needs to be found relatively quickly. It will not always detect gaps in the sequence numbers that can occur when files are deleted (for instance, if "File (1).ext" were deleted from the list above).
