In case of a file with a .alias extension which is not an alias file, could I use this error return value ? On Wed, Oct 21, 2009 at 3:49 PM, rohan a <info1686@gmail.com> wrote:

My aim here is to know when I backup what the alias file points to and then backup the alias file along with the name of the file it points to. Just like a symbolic link, where we need to know what it points to.

This looks good.

However, with a backup application, I would typically be using FSIsAliasFile() to identify an alias and then use FSResolveAliasFile() to resolve it. However,here the FSResolveAlias() file would fail causing issues. Need to deal separately with these cases

In general, you'd backup the contents of the alias file, not what it points to, because there's no guarantee that you can resolve the alias -- it might be to an item on a file server that isn't accessible, or to an un-mounted local disk, or to an item that you'd need a password from the user to resolve, or even be an alias to an item which has been deleted.
