Oracle SQL Developer query result Export Wizard default output file name

I know this is an old thread but I was looking for an answer to this, and wanted to share some information for anyone else who comes along.

As far as I know you still can't set the exact text of the file name or add a timestamp to it, but if you change the "Save As" setting in the Export Wizard window (this can be made permanent through the Tools - Preferences menu) to "Separate Files" then each export will be given a different file name in the specified folder automatically. This works even if the export is the same query. SQL Dev names each file "TABLE_EXPORT_DATA.xls" and will amend a number at the end after each export. So for example:

TABLE_EXPORT_DATA_4.xls
TABLE_EXPORT_DATA_3.xls
TABLE_EXPORT_DATA_2.xls
TABLE_EXPORT_DATA_1.xls

As discovered this is not currently possible but is currently down as a feature request with Oracle to be implemented if it gets enough attention from users.
