I think your probably looking for something like win rar? However that sounds a little fishy. What are the full file names.
When I clic on the file it takes me to a site that describes all the different types of file name extensions. It says that the file is a 'split' file and needs to be joined. It then gives a website to a freeware joiner, but this joiner doesnt seem to work?
tda-mvs8.001, tda-mvs8.002, tda-mvs8.003, tda-mvs8.004, tda-mvs8.005, tda-mvs8.006, tda-mvs8.sfv, tda-mvs8.
The files were inintially packet using Winrar. After I used Winrar to un-pack them, the files inside are the ones mentioned above. I just don't know how to join them.
