We want to expose ADS to the applications? Maybe FCNTL is a better interface to do this than magix xattrs. An application could open a file, and then use fcntl to list/open/create/delete streams? We should talk to the NTFS maintainers too as this is an ntfs feature and they might alwo want to expose ADS to apps. So we get a solution that we can use across multiple filesystems. regards ronnie s On Mon, 22 May 2023 at 16:40, Steve French <smfrench@xxxxxxxxx> wrote: > > On Sun, May 21, 2023 at 11:33 PM ronnie sahlberg > <ronniesahlberg@xxxxxxxxx> wrote: > > > > A problem we have with xattrs today is that we use EAs and these are > > case insensitive. > > Even worse I think windows may also convert the names to uppercase :-( > > And there is no way to change it in the registry :-( > > But for alternate data streams if we allowed them to be retrieved via xattrs, > would case sensitivity matter?
