because they are over protected
Many schools have policies against public displays of affection (PDA), but these are typically not mandated by law. Instead, schools establish their own rules to maintain an appropriate learning environment and to ensure student comfort. The enforcement of PDA policies can vary widely by school and district. In general, while schools can regulate behavior, they must also respect students' rights to some degree of personal expression.
All schools in the UK have a uniform policy. Only private schools do not adhere to a uniform policy.

If you asked what a file on a PDA is, my answer is everything. anything you see on a desktop computer can also be a file on a PDA. If you asked what a .pda file (having an extension of PDA), sorry, no idea. :)
PDA's can be connected to a computer. Files can be transferred from the PDA to the computer and from the computer to the PDA. Data such as phone numbers, addresses and appointments can be synchronized between PDA's and computers so the information can be the updated.
