Hi @laksh1519 ,
Place a JavaScript code activity next to data loading and paste the below script in it
logInfo(vars.filename);
After running the workflow, click display logs on JS code activity, you can find where the file got uploaded in server.
Temporary tables are work tables which used to get purged when the workflow goes to finished state (Until you enable keep the interim result checkbox in WKF properties). You can see this temporary table name by right clicking data loading activity's transition > display the target > Schema tab
