Why are files from macs often encrypted when put on an external drive and that drive is plugged into a windows system?
I'll explain what I mean 'cos they don't look encrypted at first sight, as you can open them..
but on closer inspection, they can show up green in windows explorer
and the windows cipher command shows then as encrypted, and their attribute properties show as encrypted.
I'm not the only person that has run into this, looking for example How to list encrypted files in Windows 7? one poster writes "… I was cleaning up a external hdd and came across 150 files that where encrypted. So I wanted to know what and where they were as I do not use a encryption on my computers. Turns out it was from a few downloads that I can easily get. Or seeing "_MACOSX" folders on my pc. They are always encrypted."
An example I ran into is a program I wrote in rails just a directory called "scaffoldingtest1" that I created with the command
rails new scaffoldingtest1 and i'd have copied a parent directory to an external hard drive.
I've also seen some PDFs related to adobe, from Mac users.
And they're encrypted as if they were encrypted on the windows machine, in that they can only be viewed from that windows username @ that computer. As shown in the properties of the encryption in windows. And that user at that computer can decrypt them. But they somehow got encrypted like that. If that external drive were taken to another windows computer, then they can't be read.
And i'm wondering what setting on OSX is causing that?
