This menu is available when “‘TEXT’ special” is selected. Select how to treat the end-of-line character (carriage return) for ‘TEXT’ files from the sub-menu. Files of type ‘TEXT’ are treated special: only the data fork is used, and the end-of-line character is treated special to be compatible with other operating systems. Treat files of type ‘TEXT’ special: use only the data fork and the (possibly) modify the end-of-line character. The file’s resource fork will be included in the checksum calculation. Include the file’s resource fork in the checksum calculation. The file’s data fork will be included in the checksum calculation. Include the file’s data fork in the checksum calculation.
