Hi Yu, If you cannot find the file, it is possible you need to refresh your view in the Data Choosers Tab, "General, Files" node. To refresh your view, simply click on those two semicircular arrows next to the Add Source button at the bottom of the Data Choosers. You may also have to select a "Data Source Type" of "Radar files (NEXRAD/DORADE/UF)". If you are still having trouble loading your data, you can upload it here: http://motherlode.ucar.edu/repository/alias/idvupload and we can help determine what the problem is. Please keep us up-to-date on your progress.
