Copying backup- missing file

I created a new backup of my C drive and produced 6 backup files(665.60 kb each) and one backup file (192.617 kb)
I copied and pasted all these files to my other Pc via a network but file 6(665.60 kb) was shown as 0 kb size.
I then copied file 6 and was aked if I wished to replace the existing file 6.
I said yes and copying proceeded but ended with the file still showing 0 kb
In copying and pasting I may have left file 6 not highlighted but I did epect on copying the file and pasting that the file would be there
Any ideas?

 

First confirm that all the files are still one the original drive. Next, use the TrueImage Check Image function to confirm that the image is not corrupt. If the original image checks good, try copying the file again after rebooting both systems.

 

Thanks for your help.
I discoverd that the problem was I was copying the file while I had the others files open in the other PC.
When I copied with the other files closed it copied OK
