The PD folder contains "My files" & "Other computers" everything is read/write - its a bad idea?

In the PD folder

• The contents of "My Files" being read/write is good idea for sharing between computers is good idea.
• The contents under each computer in "Other computers" being read/write is a really bad idea. "Other Computers" should be read-only. It doesn't make sense to able to alter the backups of other computers

Each computer directory in "Other computer" you can:

• Create a new directory anywhere in another computer storage space
• Create a new file anywhere except in the root directory of another computer storage space.
• Modify any existing file or directory of another computer storage space.

The "Other computer" directory contains backups and they can be corrupted by additions, deletions and modification by other computers. If you had something that went rogue it could seriously mess with the backups of another devices.
