|If the file ws saved to CD NTFS or FAT32 doesnt enter into it. The file will be saved in a format compatible with the CD Drive. You cannot write files to a CD in NTFS or FAT32 format or any other hard disk format. What format the file was saved in originally is totally irrelevant.|
If you saved this file using a packet wrinting software then that is why you cannot read it. Packet writing softweare is not standardised and if you just clikced and draged the file to the CD that is probably what you used. You need the same packet writing Software on both computers, something like Nero InCD.
You need to save the file in ISO 9660 file format which is standard. I file written in ISO 9660 forma can be read by any computer, even a MAC and all CD burning software supports it.
Better still, get yourself a USB pen stick. That will use FAT32 and and will save the hastle fo burning a CD just to transfer one file.
