I'm missing an important file and I don't remember deleting it from my Dropbox account.

Hi asherbono! Welcome to our Community. 

Do you remember when was the last time you could access that file on www.dropbox.com? Was it a personal file of yours, or was it shared with/by someone else?

Besides your Events page, have you also checked your Deleted files and Shared pages? 

Let me know.

Thank you for the quick response. Yes, it was a personal file and a sensitive one :(  . I looked in the deleted and share and there isn't anything 

Hey asherbono​, let me also jump in here! 

Do you recall when it was the last time you saw the file online?

You mentioned that you checked your deleted files page, and your sharing tab but what about your events page? What does it report? 

Can you send me a screenshot of what you see there? 

HI! Thank you for your response 
The event page is empty, but I can only check one day at a time 

Hey asherbono!

Are you sure you're checking the correct Dropbox account? Is it possible that you have another account that you used to upload the file? 

Also, do you recall how you added the file to your account in the first place? Did you upload it using our website, or desktop app? 

Hi, 
It was using your website 
I editied it many time using your Online Excel editor 

I don't have any more account - I'm sure this is the account ( as I see all other of my files ) 

Hey asherbono, since you don't know what happened to your file and cannot locate it anywhere, I just sent you an email, so we can investigate this internally.

Just get back to me when you can. :)
