I have an iso that is in 4 parts what do I do with it?

[GaZa]

-Put all 4 files in the same directory (eg: c:\)
-Start WinRAR
-Put via drag & drop the *.001 File in WinRAR
-extract the file(s)
-burn it!!!

*.cdi -> you need Discjuggler
*.cue + *.bin -> you need CDRwin
*.nrg -> you need Nero


Have fun!!!
