Lesson on Image Files
My jump drive totally freaked me out today. I had all my documents and data from home transferred to my jump drive before I left home and I planned to copy those files to my computer here at school. So on the desk was what I thought was my jump drive and when I plugged it into my computer, none of my files were there. Instead, there were a bunch of items on there with a file extension of DMG. I was so freaked out! I though someone had corrupted all my files from home!
So I woke up Alex and asked him what was up with my jump drive? Like, did he take it and do anything to it like erase my files? Did he see anyone else messing with my jump drive while I was at work last night? I was so freaked.
Of course, Alex didn’t do anything to my jump drive. turns out the file extensions for DMG are for Apple computer image files. If I had thought about it for a minute I would have realized that I had picked up Alex’s jump drive and not mine. But I didn’t even realize that Alex used a jump drive that looked exactly like mine!
So I ended up learning about file extensions and even though the Mac runs a lot of the same programs as my PC, the file extensions for image files are different. In fact, the new Macs use different extension files than the old Macs, and sometimes you have to fix your old files to be read on the new Macs. There’s even a site online that does that for you automatically. They have a whole library of file extensions and ways to fix files. So I looked at the page for File Extension DMG and found all the information I would need to fix the extensions from old Macs. that’s good to know and when I showed it to Alex he bookmarked that site so he can find it again later.
