Wow, thanks fellows, didn't expect that much help.
I wish I could post the message but I already deleted the file, because I already had pieces of what I wanted in other files. Should have come here at the time, but I had to clear the space. So I can't post a screenshot ...
The file, a .mpg file, would neither move nor copy to another directory on the computer. I have two hard drives, so I was moving from C: to a drive on the other HD. All the other .mpg files moved, including some of several GB's, but this one gave the error message that it was too large to be moved. Nor would it copy.
The thing is, I am now ready to record another Webcast, and will be creating more large .mpg files. To limit the size of the file would interfere with my recording, cutting out small pieces of the webcast and chopping it up. I prefer not to do that, if I can figure a way around this problem.
Sorry this is not real-time thing where I could give you more precise info. I am reformatting my computer later today, and when reloaded I'll be able to format my EHDD to NTFS from Fat 32, which I assume is necessary. I also plan to partition the 320GB OS Disc and use the rest of it for temporary storage for projects like this. The previous file in the OP was recorded onto C:, as it wasn't partitioned.
So as long as I can record the webcast, temporarily store it on a partitioned drive on HD#1, where the OS also resides, then transfer to the HD#2, or my EHDD formatted in NTFS, I'll be good.
But naturally, I'm a little spooked by the previous experience. What do ya'll think?
