How to delete multiple submission

I am needing to delete a large number of entries at a time after I have processed them, but do not want to delete all entries.  It is very time intensive to click on the red X to delete each individual entry, yet I am usually not in a position to use the Delete All feature as new entries have come in while I have been processing the current batch.

It is possible to select multiple entries (CTRL + Click and/or SHIFT + Click), and then delete them at once.

Also, there is a Time Frame filtering option available, so you can delete the filtered data.

Please take note that deleted submissions are permanently gone. 

So you should also make sure you have a copy/backup of them in case you need those submission data later on.

Hope this will help. Let us know if you need further assistance.
