Error 0x80070780 when copying a file out of Dropbox folder even with Dropbox uninstalled

Hi,

I found that I could not open, copy, or move any files under the DropBox folder. The only thing I could do was delete. It must be a very curious security setting that would allow you to delete a file but not to read it (Open or Copy are effectively a read option - Move is effectively a Read and Delete operation).

I had already uninstalled DropBox.

I have deleted everything under the DropBox folder and then the DropBox folder itself.

I have changed references from the standard system short cuts such as documents back to their original locations eg C:\user\<me>\Documents

I have then recovered my data from an external hard drive.

I am sure that you might want me to work with Microsoft and Dropbox to get to the bottom of what caused this. However, you can also probably understand why I am not going to risk using Dropbox again.

I have already lost 1.5 days of my time

I have lost a small amount of data, but fortunately as it was a new laptop I had only changed a few files since the last backup was taken, and all my email is on an Exchange Server.
