I am having a similar issue to that in a recent post - I discovered this morning that two files saved yesterday were missing from my Dropbox folder, both as viewed through Windows Explorer and as shown on the Dropbox website. However, when I checked "recent documents" in my word processing program, I was able to open them, and when I checked their location, it was showing as that same folder.
I followed the advice in the recent post and others, and looked at the Events page, but there is no record of these two files being deleted.
It would be good to have some reassurance that this will not happen again, and that it has not been happening to other files without my knowledge. I am working on a large project with 100s of separately saved documents, and I sometimes leave a chapter for several months so would not necessarily notice one of these deletions within a 30-day period.
Thank you!
