Share a single document by link or email invitation with view, comment or edit permission. Add an expiry date and a password, see who opened it, and revoke the link when you are done. This is document sharing, not a virtual data room.
Choose view, comment or edit for each person or link.
Give a link an expiry date, after which it stops working.
Protect a link with a password. DocFila checks it on the server and limits repeated attempts.
Turn a link off at any time. New requests are refused straight away.
For people you invite, DocFila records who opened the document and when. Public links keep a view count.
DocFila does not have a virtual data room. There are no dynamic watermarks, NDA gates, per-page viewer analytics, built-in Q&A or IP and country restrictions. Revoking a link stops further access through DocFila; it cannot recall a file that someone has already downloaded. For a copy that is only meant for one person, password-protect the PDF or redact what they do not need to see before you share.
Keep going with the document workflow that matches this page. Open the tool you need, then finish the file in DocFila.
