My sister sent me a recommendation for dropbox. It is where you can upload your files by putting them into a folder and then share them (as with photos). I chose all of my photos and was uploading them but it was taking too long, so I took the folder and threw it into the trash. Then I couldn't find my photos not long after that. Dropbox states it is simply a folder where your pictures are at and is not a copied folder. So I lost the photos that were not already uploaded when I tossed the folder. I reinstalled dropbox so I could see photos I had already uploaded and so I could reacquire them. Now I have 2 dropbox folders under places and am scared to mess with them. And I am pretty sure that under my name in places, that some folders are no longer there. Such as the utilities folder. I'm totally confused as to whether or not the system is as it should be. I did not buy a back-up drive until after that fiasco, I kept putting it off. Yes I do repair permissions although I do not really understand it. If I use the disks that came with my system, will it be put to rights? I'm freaking out because I do not want to screw anything else up.
