Hello,
The subject says it all. I accidentally uploaded a very sensitive file containing my personal information on my other account. It was in my shared folder (shared folder with 1 friend) for about 1 hour but my friend didn't see it. I unshared the folder and then deleted the file. Permanently. Now my friend can't even see the folder in his Dropbox so I guess that worked.
The file is now permanently deleted and I didn't see the file anywhere anymore on my Dropbox. I also deleted the account the file was uploaded on. Can I be sure the file and it's data was deleted from everywhere or do I still have something to worry about?
