Microsoft has issued a hotfix after receiving more than 100 complaints concerning a bug in Windows Vista that makes it difficult to copy files from one disc or PC to another.
The bug affects a function in Vista that calculates the time remaining to complete a file copy.
One user on the Microsoft Technet forum said, "When moving a file (size not important) from drive C to drive E (both Sata II on same PC), it takes ages for the green progress indicator in the address bar to reach 100%. File transfer starts but the progress indicator doesn't move." After an indeterminate period, transfer starts moving the progress bar along to completion.
Another user experienced the same problem using a virtual private network to copy files from one PC to another.
"Transfers are essentially impossible to get working. It will sit at 'calculating time remaining' for five to 10 minutes then tell me the file is not available," he said.
He added that the files could be copied and pasted between his Windows Vista Business Edition PC and a Windows Vista Ultimate machine via the clipboard by running Microsoft's Remote Desktop Protocol.
Microsoft has produced a supported hotfix for the problem. On its support website, the company said, "Apply it only to systems that are experiencing this specific problem.
"This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Windows Vista service pack that contains this hotfix."
