Error 0x800704C8 user-mapped section open

[Bruce]

I am running Vista Ultimate (with a clean install rather than upgrade.)

Quite often, when I use Windows Explorer to copy a group of files to a
different folder, I get a dialog box with this error message....

Error 0x800704C8: The requested operation cannot be performed on a file with
a user-mapped
section open"

The good news is that I can simply hit the "try again" button and it copies
fine. The bad news is that the same dialog box pops up repeatedly for many
if not all of the files that I am copying. Gets very old, very fast.

The error message means nothing to me. My Google searches of newsgroups has
yielded little, other than a set of other people frustrated with similar
challenges.

Can someone explain the problem and propose a solution?

thanks, Bruce

I am getting the same error ALOT - very annoying.

Any help would be appreciated!

I just started getting this error message recently. Running Vista Home
Premium. This morning, I selected about 2GB of files to copy from one
Explorer window open on my local hard drive and dragged them to another
Explorer window which was open on an external hard drive. I started getting
this error message on several files. After just clicking on OK each time, I
closed the source explorer and then everything copied with no more error
messages.

Hi All
Hope this is of help, it may sound simple, but you do say you are trying to work with "FILES". I needed to get round this quick because I was getting the same messages with photo tranfers in large numbers - like 80 photos or more at a time, stored by default in Vista "photos" folder.
If you do "skip" or "try again" some of the photo's went missing.

If you transfer the FOLDER (vista does not know whats inside) so the problem goes away and you do not get mucked about.

Better still don't use Windows ready made default folders like My Pictures, My music, or vista equivalent. Make your own default folder to drop data into initially, that Windows or Vista does not have a handle on - transfer the data by the folder, open the folder, check the data - should all be there no problem!
Good luck

1. change the name of the file and also change the extension.
2. restart and shift+del the file.
