       <b>Q</b>: Is there a size limit to a tar/zip creation through the web UI?<br/>

       <b>Q</b>: A file/folder icon is marked with an 'X' and there is no download link. What does this mean?<br/>
       <b>A</b>: It means that the file/folder is not in place and cannot be directly downloaded, it has to be "recalled" first. This can be done by selecting the file/folder checkbox, clicking on the <i>Actions</i> dropdown menu at the top of the page and then on <i>Async recall</i>. This action will start an asynchronous job to recall the file/folder and make it available for download. An email notification is sent to the job owner when the job is queued and when it completes.
