'primitiveDirectoryEntry' module: 'FilePlugin'> returns 5 values in Cog<br class="">
and 7 in Squeak. The 6th value are the file permissions and the 7th is<br class="">
a boolean (haven't looked to see what it represents).<br class="">

I noticed this with some Pharo and Seaside images when attempting to<br class="">
open the world menu -> Tools -> File Browser which results in an error<br class="">

I'm assuming this is not an intentional behavior difference. But if it<br class="">
is, any details as to why would be appreciated…</blockquote></div></div></div></div></blockquote><div>we added posix permissions and symlink flag. </div><div>and we changed it not because we have a different abstraction, we changed because information was not enough. </div><div>we will add also owner and group soon also, but most probably it will be </div><div><br class=""></div><div>cheers, </div><div>Esteban</div><br class=""><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
