Folders/files are copied when they are dragged to be moved

If you drag an item from one volume (disk) to another, it will be copied. Is this perhaps what you are doing?

If you try to delete a file owned by the system, you must enter an admin password even if you are logged into an admin account.

Are you using an admin account or a standard one?

And are the files in that account or a shared folder?

As for the authentication, check the permissions on the files; right-click and 'Get Info'

Check that you have read and write privileges for the files.

It's behaving as if the Option key is stuck in the down position.

Do you see the plus symbol in a green dot below the pointer when you move something from one folder to another? That would be an indication that the item is being copied rather than moved.

You might check System Preferences > Keyboard >Keyboard tab > "Modifier Keys …" button to see if anything looks strange and/or click on the "Restore Defaults" button to reset them.

Also, I assume you are using an Apple keyboard. If not, let us know.

Something is weird. Good question about the KB, R C-R.

Only one folder, eh. Well, one can't be sure as there are countless.

You should probably replace that folder with a new one. Easy to do.

Have you done the normal tune-up - reset PRAM, repaired permissions . . .

Not all files have the this problem only one folder.

It would have helped if you had mentioned this earlier. Are you talking about a destination folder (where you drop the items) or a source folder (where you dragged them from)?

Disk permissions have nothing to do with file permissions on individual accounts.

Don't worry about the list of messages - they'll be there every time.

As discussed in Mac Geek Gab 355, Access Control Lists (ACLs) are permissions that impact user-level access rights within OS X. They are different from Permissions, which impact system-level rights. In simplified terms, items inside the user’s home folder are regulated by ACLs while items outside the user’s home folder are regulated by Permissions.

Due to this distinction, using Disk Utility to Repair Permissions will not resolve issues related to objects in the user’s home folder. To resolve these issues, we need to “reset ACLs.”

In OS X 10.6 Snow Leopard, boot to the Mac’s install disc by inserting the disc and holding down the “C” key at startup (or holding Alt/Option and selecting the disc from the boot menu). Once you’ve selected your language and are at the installer’s main menu, choose “Utilities” from the menu bar, then “Reset Password.” This menu allows you to reset user account passwords but also allows you to reset ACLs by choosing a user account from the top menu and then clicking “Reset” at the bottom of the screen.

The Reset Password Menu in Snow Leopard and Lion’s Installers lets you reset your Access Control Lists

In OS X 10.7 Lion, Apple removed the Reset Password option from the Utilities menu in the Recovery Partition. Dwight Silverman over at the Houston Chronicle found a workaround: boot to Lion’s recovery partition by holding “Command-R” at startup (or holding Alt/Option and selecting the recovery partition from the boot menu). Then, from the Utilities menu, choose Terminal. Type “resetpassword” into Terminal and hit Return. This launches the Reset Password menu. From here, proceed as you would have under Snow Leopard.

Once the process is complete, exit the utility and reboot. This should resolve any permissions issues involving user-level objects. Thanks, Dwight, for the great tip!">
