I recently have been unable to open doc's (MP3s/word docs etc.) on other computers after I have saved them from my laptop. I am as sure as one can be that there is no viruses/spyware interfering with these. There are no compatibility concerns. My sister had the same problem, in that she can easily open her university office docs, written and saved on university computers, however once they have been opened, edited and saved again, on my computer, the memory stick can no longer work on the uni computers, but will work fine on my laptop.

In summation my question is this: Is there any way that my computer coule be write-protecting/locking files after they have been used. I realise this is an unusual question. Any tips on the right-direction would be greatly appreciated.
