Hi Marci,
In cases where the experiment is loaded from a file share, or the data path is set to a file share, Inquisit will save each participant's data to a separate file with a unique file name that includes the date and time and the subject number.
The best way to do this is to specify a share in the data element, for example:
<data>
/ file = "\\myserver\mysharefolder\"
</data>
The key is to make sure the path begins with "\\", as that's how Inquisit knows it's saving to a share.
Hope this helps,
Sean
