It would be better for me to use FSResolveAliasFile() for identifying
aliases instead of using FSIsAliasFile(). "wasAliased" is set to TRUE
if the input is an Alias otherwise FALSE.
Also, if it cannot find the target of the alias or if a file with
.alias extension is not an alias it returns an error. This should be
enough for me.
Thanks
