The shared lab account and the disappearing project folder
At a government higher secondary school in Nagaon, 60 students share 12 lab computers that all log in with the same account, 'student'. Each computer has a 120 GB drive with about 2 GB free. Project files are saved on the Desktop with names such as final.doc, final2.doc, project_final.doc and NEW.doc. Last week a student deleted a folder containing a week's work, another student saved over a classmate's document, and the lab assistant cannot tell which file belongs to whom. The teacher has two lab periods before the practical examination and wants a simple system that students can follow without individual Windows accounts. She also needs to recover the deleted folder if possible and free space safely.
1. Propose a folder and file-naming convention for the lab, with an example path, and explain how it prevents overwrites and blame games.

Use a top-level work folder such as D:\ITL2, then class folders, then one folder per student: D:\ITL2\Class10A\Roll12_Anjali\ProjectName_2025-02-14_v01.docx. The roll number and name make ownership visible; the date and version number prevent two people choosing the same 'final' name. Keep a separate read-only Resources folder for templates and a Submit folder that students copy into only when the teacher says so.
This works because the Desktop is no longer the default save location, and the path itself identifies the owner. A short wall chart and a five-minute demonstration are enough. The teacher can also ask students to save with Save As into their own folder, not just Save, which is the common cause of overwriting a neighbour's file on a shared login.
2. The deleted folder is not in the Recycle Bin. Outline the recovery steps and the order in which they should be attempted.

First stop using that computer for saving work, because new files can overwrite the deleted data. Check the Recycle Bin again, including 'Restore all items', and check whether the folder was moved into another student's folder rather than deleted. Look in File History or a previous version if the lab has it enabled. If the drive uses restore points, try System Restore only after backing up current work, because it can affect installed programs.
If none of these work, use a reputable file-recovery tool on a copy of the drive or ask the school's technician. Do not install recovery software onto the same drive if it can be avoided. Going forward, keep a weekly copy of the class work on an external drive or the school's approved cloud account, and test that the copy opens.
3. Without individual Windows accounts, how can the teacher enforce accountability and still keep the lab usable for 60 students?

Accountability cannot come from Windows permissions when everyone is 'student', so it must come from procedure. Use a lab log with date, computer number, roll number, start and end time, and a quick teacher initial. Make each student responsible for one folder and check it at the end of the period. Appoint a group leader per computer to report problems, and keep a simple incident book for overwrites or deletions.
If the school can create local accounts, that is the stronger fix because permissions follow the user. If not, the teacher can still set the Submit folder to read-only for the shared account and collect files through a supervised copy step. The aim is a visible record plus a routine, not surveillance: students should know where to save, how to name files and whom to tell when something goes wrong.
