What are reasonable PDF file permissions?
Lately I've found that inside a directory, with many PDF files, all files have all possible permissions set on. Being uncomfortable with that I thought about changing them. However, I don't know what be reasonable for PDF files considering that I want to be able to open and, sometimes, change them (e.g. PDF "text maker").
Here a print-screen for how I've found them (

I suppose that the initial permission set was lost while I've copied them from a backup HDD. Could you please consider example-peaking a effective way of copying them around without loosing their permission settings. Thank you.
