CIFS error

[cmeinck]

I was trying to load some content into Alfresco via a sytem folder, but when I navigated to the folder I got a "The local device name is in use." error in Windows.

I also got this exception:

Is this a known problem?

Hi,

Sorry for the late reply.  Yes, this is an issue, but has been fixed.  System folders are no longer displayed in CIFS - just as they are not displayed in the web client.  Additionally, the system folders didn't have a name assigned to them.  This has been changed so that anything without an explicit name will spoof a name.

In short: Fixed!  You can get the nightly build or wait for the next release, which will be out early next week.

Regards
