I recently saved a 12.5GB file to hard disk from a video camera and wanted to back this file up to DVD (or something) so I needed to split the file into smaller pieces so that I could save the pieces and reassemble them again later if I had to. I went looking for file splitting utilities and found loads. A rather nice looking one took my fancy and I installed it. It told me my 12.5GB file was 600MB..........<sigh>.
So, I wrote my own, paying particular attention to handling all file sizes and calculations using 64-bit numbers ensuring that the utility would work for virtually unlimited file sizes. The neat thing about the utility is that when you have used it to split the file into chunks, it also writes a small batch file that will stitch the chunks back together into he original file again - without needing the original utility. Of course I proved it on my AVI file and checked that the Windows FC (file compare) utility passed a binary compare of my original 12.5GB file and my re-joined split file.
Click here to download ArtSplit.
To use ArtSplit, unzip it and run the EXE file ArtSplit.exe. Specify a 'chunk' size (e.g. 600MB for CD, 4500MB for DVD etc) and then click 'split'. A new folder will be created with the split contents together with a re-joining file.
