"copy or move Thumbs.db?"

The file is a small database of thumbnail images so that you can view a particular folder in thumbnail view. If you move it, it is no longer accurate for the folder it sits in (corrupt) and will simply re-generate itself in the folder you took it out of.

If you are FTP'ing files to a server, just don't upload that file. Especially if the server is Unix based because it can't use that file anyway. It's a Windows "thang". ;)

Hide the Thumbs.db files so they are not selected when transferring the contents of a folder. By hiding them, they will not be selected when you 'Select All' and 'Copy.'

Open My Computer, open the Tools menu, select Folder Options, click the View tab, put a dot in front of 'Do Not Show Hidden Files and Folders,' and lastly click on the Apply and OK buttons.

The first question is, do you use the thumbnail view when you open or explore your folders?

If the answer is no, then allowing the thumbs.db file to be created slows your system down and uses unnecessary disk space.

As far as not copying the file, you can get some relief if you change the windows explorer setting for system and hidden files to hide those files.
You should no longer grab thumbs.db when you copy files from a folder. But, it will still move when you copy or move a folder.

I'm sure that there is a registry hack that can disable the confirm copy or move dialog. I do not know the registry intimately enough to tell you what key to modify.
