Quick answer: To share an exam paper safely: upload it, open More options, set "Available from" to the exam start and "Close the link at" to the end, set "Who can open the link" to the student emails or your school domain, and add a per-person download limit. Give it a short link like sharelargefilesfree.com/class10-maths to write on the board. Before the start time students see a countdown; after the end the link closes. Free, no accounts for students.
Release a question paper at an exact time
- Upload the paper the evening before.
- Open More options. In Available from, pick the date, time and time zone the exam starts. Until then the link shows a countdown and nothing can be opened.
- In Close the link at, pick when the exam ends. After that the link says it has closed.
- Set a Custom short link such as class10-maths (see short links) and share it in advance.

Send to the whole class at once
Create a contact group such as "Class 10-B" by pasting names, emails, phone numbers and roll numbers, or importing a CSV. Pick the group when you send by email, and on your Transfers page you see who has downloaded by name and roll number. Students who have not downloaded can be reminded by email or with a tap-to-send WhatsApp message.
Class notes and lecture recordings
For notes and recordings you usually want the opposite: easy access for the whole term. Upload lectures in original quality (up to 20 GB), choose the longest expiry, and share one short link per chapter. Students who miss a class can watch or download later without anyone needing an account. For recordings too large to send, see compressing video without losing quality.
Frequently asked questions
Can I release a question paper at a fixed time?
Yes. Set "Available from" to the start time; the link shows a countdown until then and opens exactly on time.
Can the link close automatically after the exam?
Yes. Set "Close the link at" to the end time. After that nobody can open or download the paper.
How do I stop the paper spreading to other schools?
Allow only your students' emails or your school domain, limit downloads and devices per person, and optionally allow only your country.
Do students need an account?
No. At most they confirm their email with a 6-digit code.
Can I see which students downloaded?
Yes. The Transfers page shows who opened and downloaded, with names and roll numbers from your contact group.
