It will only tell you it hasn't found the target. Eg, a regular file, say xx.alias, will be indistinguishable from a genuine alias who's target is on an unmounted filesystem, has been deleted, or is otherwise unavailable for whatever reason. paulm On 22/10/2009, at 5:44 PM, rohan a wrote: I see that FSResolveAliasFile() fails when its cannot find target of the alias with the error fnfErr. In case of a file with a .alias extension which is not an alias file, could I use this error return value ? 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.

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.
