You do need a hard drive to download expansions, but the system won't turn on if you don't have a hard drive, so if you can turn it on without problems, and can play games then you definitely have a hard drive and you are able to download expansions.
no because the computer won't download the program properly and your more likely to mess with the drive inside it
Yes, you can but you have to have a program on your computer and you would need a flash drive
You open the torrent file in a program such as limwire. limewire will download that torrent and save it to your hard drive.
That means you've run out of storage space. Either get a bigger storage drive or delete unwanted programs.
Hard Drive
If your on ps3 or Xbox save your person to a flash drive. Download a program called willow tree on your PC. Use the flash drive to upload your guy to willow tree, you can edit his play through and other stuff
If a program's executable file or setup / install files are not saved to the harddrive, no, the program will not run without the disk in the disk drive.
Well, you can't. Not like that anyway. You need to find out what the file type is and then download a program to open it. Do a search online for the file type. If it's something like Microsoft Word, you can download a viewer and don't necessarily have to download the program. I'm assuming you mean that the file is unrecognizable. If its the flash drive you need to download drivers for it or you may be using a drive not compatible with an older (Win 98 for example) computer. ~ TTry reinstalling it again
Downloaded files always make a temp file in your computer, no matter you delete it or not there is always a way to recover it. So you can not download and copy files from a system without leaving a trace.
