Hi. Just started yesterday. I have the same question but for PC. My use for Dropbox is primarily for storage. I don't want to sync my files on my desktop. I want to put them in Dropbox as an archive. I did a trial with a small Word doc. I "uploaded" the doc and immediately got a green synch icon at the corner of the doc on my lap top. I went to Dropbox. Said it would take two seconds to upload. That message stayed the same all along. I could see the doc from Dropbox. It seems to be in Dropbox. But when I go back to my laptop desktop and delete the file, it tells me that I will be deleting the file in Dropbox AND on my laptop. I don't want this. Ultimately I have too many files to put in dropbox such that they would take up all my hard disk space. I want to put the files in Dropbox as archival backkup. I don't want the taking up space on my hard drive. That was the whole reason I got Dropbox. Am I misunderstanding that Dropbox DOES NOT operate as a storage device?
