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 linear search to find a unique file name, so it is suitable for situations where there are a small number of collisions for each file name. This will detect and fill gaps that can occur when files are deleted (for instance, if "File (1).ext" were deleted from the list above).
