Mass update and mass upload

Mass update and mass upload

Hello Zoho Team, I have 2 questions. I have a lot of candidates to update so I filter the ones I want into Zoho and do my mass update (I put the display of the list on 100 candidates). But when I update these first 100 hundred ones, I lost my reseauch and get back with all the candidates in the list. Is there any way to update a full list of candidates (more than 5000)? Also, is there any possibility to upload a lot of cv (pdf and word) instead of 10 by 10? Regards, Olivier
