My operating system is Windows XP including all available service packs. I
regularly download pictures from our cameras to folders created in My Docs/My
Pictures with no problems. Yesterday I downloaded 83 pics plus one camera video
of 420 MB for a total of 971 MB from a Canon camera. However, one large video,
1 GB, on the camera would not download. I could access and run the video on the
camera via USB connection but I could not transfer it onto the computer – no
matter what we tried. The only reason we could think of was a limit on the
transfer size. Is this case? And if so can we override it?
In this excerpt from
Answercast #87, I look at various reasons why the transfer of a large video
file from a camera might fail.
Copying a large video from a camera
No, there’s no limit on transfer size.
Unfortunately, you haven’t told me how it fails. Were there any error messages? That’s usually the first clue we need to understand exactly why something like this isn’t working properly.
Enough hard drive room?
The other thing that comes to mind – that is easy to overlook… a GB is a fairly large file. Do you have a GB of free space on your PC? In other words, could it be something as simple as not having enough room on the destination for that file to fit?
The fact that you can view and watch the video over the USB connection means that the USB connection is working – and in fact, that is a file transfer. It’s very much like a file copy. That’s actually transferring the entire file to your PC; it’s just not writing it to disk.
So, the first thing I would check on is making sure that you have enough room on your PC for that file.
Hard drive errors
I’d also run ChkDsk in case there were some kind of an issue on your computer’s hard drive. This can sometimes be an issue when running into a problem with the disk file system. It could be getting confused somehow.
Flash memory card
The other approach (as suggested by my assistant) was to actually remove the flash memory card from the camera and use a flash card reader to transfer the files over – rather than going through the camera’s USB interface.
I actually prefer that method. I don’t like running my camera’s battery down just to transfer the files. So I’ll usually pop the memory card out of the camera, insert it into a reader, and then copy the files over that way. That would be something else to try.
