I don't know about other people's problem with moving files and invoking that error, but as for deleting files, I believe King Computer Solution's post:
"In windows 8 in the view toolbar Press the Preview pane to turn preview pane off"
is the best solution.
I think a good question to ask, maybe to narrow it down: Is "Preview Pane" active when the message is received by those performing the action that invokes the message?"
This may be why Microsoft doesn't address it, because there's a solution and they probably figure that someone knows, or will eventually figure out and pass the word through these forums. Such as King Computer Solutions has done.
It really was that simple. It was driving me nuts as well. After reading KCS's response it then made perfect sense. Because to be able to give a preview the file has to be "read," thereby invoking the message if an action is attempted on the file. For example,
before finding this solution, I found that if I closed all of the folders, or the folder that the file was in, then the action would perform.
Anyway, enough of my long-winded reply. Thanks for sharing KCS!!!
P.S. I do think that's a valid question, so as to see if there's a common denominator with the issues. So again, to everyone with this problem: Is "Preview Pane" active when the message is received by those performing the action that invokes the message?"
And if it is try making it inactive, perform the action again, and report back whether that solved the issue or not. I'm curious to know.
Cheers!
