What is .FSS file extension?
Split archive file created by Splitty, a file splitting and joining utility; contains one part of the overall split archive; requires a master split (.FSM) file in order to merge the file back together with the other FSS files.
FSS files are named with an index plus the ".fss" extension. For example, a split archive for video.wmv would have the filenames video.wmv_1.fss, video.wmv_2.fss, etc. Additionally, the split archive would have a master file called video.wmv_0.fsm.
NOTE: Splitty can split files by a maximum file size or by a target number of output files.
