How to Design and Check File Distribution in Class

Kota 2025-08-23 · 2026-07-18

Sharing files in class is about more than reducing paper. Deciding who receives what, by when students must receive it, and where it will be saved afterward can reduce questions and mistaken distribution during class. A QR code simplifies the entry point; it should not be used to skip operational checks.

Divide Materials into Three Groups Before Class

First separate materials that may be public, materials for class participants only, and materials containing personal or assessment information. Even participant-only materials should not be treated like ordinary handouts if they contain names, student numbers, answer sheets, or contact details. Keep shared files separate from management documents such as submission lists and grading sheets, and extract only what is needed for distribution.

Put the class name, session number, material type, and version in the filename. A name such as “Information_Security_03_Exercise_v2.pdf” makes it easier for students to notice when they open material from another week. When a version changes, make clear whether you will create a new share while leaving the old one or switch the distribution method.

Steps for Displaying a QR Code in the Classroom

1. Before class starts, scan the QR code with a test device and confirm that the sharing page opens.
2. Check the retention period and password, and set only the period needed after class ends.
3. Before displaying it, check that people outside the class cannot photograph the QR code.
4. After displaying it, provide the URL and receipt instructions separately for students who cannot scan it.

In an online class, the QR code or password may remain in a recording. If you distribute the recording, confirm that its viewers are the same as the intended recipients and, if necessary, provide the information another way without displaying the QR code on screen.

For Assignments, Treat Distribution and Submission Separately

FS!QR QR sharing can be useful for handing out materials, but it does not automate receipt management or grading workflows for submissions. If you use it for assignments, separately define the destination, filename, deadline, resubmission rules, and how to confirm a successful submission. If submitted files contain personal information, prioritize a submission system approved by the school.

What Teachers Should Check After Distribution

• If a student reports that the file will not open, check expiry, password, browser, and file format in that order.
• When distributing an updated version, tell students to check that they are not using the previous version.
• When class is over and the share is no longer needed, delete it manually or check its expiry.
• Explain that the service cannot delete materials saved on devices or screenshots.

When School Rules Take Priority

For materials containing grades, identity documents, health information, or individual accommodations, follow the school's information-management rules and the responsible department's instructions. FS!QR supports short-term material handoffs; it is not a replacement for a school administration or learning management system. Before using it in class, confirm the data types and storage location with an administrator.
