I have saved my files, I know I have because I copied them onto my dropbox by clicking and dragging the files on April 30th. Now, I opened the files from my computer and they are dated April 27th and everything is lost that I did between the 27-30... Help! Thankfully I did save it to dropbox but I can't rely on that. What happened?!?! I noticed that when I was working on one of the files when I opened it up and all the work I did the day before was gone and I had to re-do it.
Did you possibly save them to a different folder?
No. I always just hit save. Then I click and drag the file over to my dropbox so I know the file was saved on April 30th because it is the complete file dated April 30th in my dropbox. I don't understand how this is even possible! How does a file revert to a previously saved version days before?
