Hi
Here is the scenario, students submit their works as PDF file. I download them to my iPad correct them, zip the corrected files and upload them.
Now suppose, after this correcting 2 or 3 more students have submitted their work. If I again download all of the PDF files, but just correct the new ones, and leave the one I already corrected untouched,
make a zip and upload that zip:
Will then my corrections overwritten, for those students I have already corrected the files?
I am asking this because the zip will contain 3 corrected PDF files and say 5 not corrected ones (since I did this already)
One option to avoid this possible danger is only to make a zip of the files I correct and delete the other.
Or I select the files I want to correct and download them as a zip.
But I just want to be sure what happens in the case I don't take these cautions.
Thanks and regards
