Ago 2-3 weeks I saved a couple of files to my Raspberry Pi SD Card , and then gave the RPi to my dad (he used his SDCard , I kept mine) , and now I need those files but I don't have any RPi left , is there any posibility to take those without a RPi or I need one ?
Normally it is not possible to read out the sd card without a special software. Because Linux used another file system than Windows.
The best way is to download a 'Live CD' and temporarily boot that on your Windows computer. With this way you can run a Linux without installing it on you machine. With Linux it is easy to access the entire SD card. Search your files and store this on a stick.
When you're done you take the CD out, reboot and go back to your Windows.
