DESCRIPTION:
We received an SHARINGVIOLATION or ACCESSDENIED error. We want
to generate the most accruate error message for the user to inform
them better. These are the cases we care about:
ERROR_ACCESS_DENIED: This is the legacy case with the message:
"Access is denied. The source file may be in use."
DE_DEST_IS_CDROM: This is displayed in case the user copies a file to
their cd-rom drive.
DE_DEST_IS_CDRECORD: user deletes from CD recordable drive, we need an error
message that isn't so scary about "cant copy files to CD".
DE_DEST_IS_DVD: This is displayed in case the user copies a file to
their DVD drive
DE_SHARING_VIOLATION: The file can't be copied because it's open by someone
who doesn't allow others to read the file while they
use it.
DE_PERMISSIONDENIED: This should be displayed if the user doesn't have
the ACLs (security permissions) to read/copy the file.
