I have encountered this error a number of times and I believe it to be a Windows issue (I am running Windows 7 64bit). I am trying to copy a 5.56GB file onto a pen-drive that Windows (and DOPUS) tell me there is nearly 14GB free but after copying about 4GB of the file DOPUS reports there is not enough space but the properties of the pen-drive says there is still 13.6GB free!
Could it be that the file system of the pen-drive is FAT32?
I have attached screen shots to show the issue.
Thanks in advance.
