File TypeWinOptimizer Split Archive Part 1
What is a PART00000 file?
First part of a split archive created with WinOptimizer, a maintenance and optimization program for Windows; created by the File Splitter & Joiner tool provided with the program; can be joined with other parts (i.e., ".part00001," ".part00002," etc.) to restore the original file.
WinOptimizer appends the part number to the end of the filename when creating split archive parts. For example, MyMovie.wmv would have parts MyMovie.wmv.part00000, MyMovie.wmv.part00001, MyMovie.wmv.part00002, etc.
NOTE: Split archives are used for separating large files into smaller parts for storage on floppy disks, CDs, and DVDs.
