“Can't open the file because the file format/extension is not valid.” error on website/desktop app.
Hi, I’m having a serious issue with Dropbox where many of my files appear in the correct folders on both my computer and on Dropbox.com, but none of those specific files will open. I receive errors like: “Cannot open the file because the file format or file extension is not valid.” Here’s what’s happening: I can see the file names and folder structure in Explorer. I can also see the same file names on Dropbox.com. But when I try to open any of these files (locally or on the web), they fail with format/extension errors. The files appear to be zero‑byte placeholders rather than real files. Most of my other files still exist on my second laptop, but the ones I urgently need do not. These missing files appear in Dropbox, but none of them open anywhere. This all started after repeated issues with the Dropbox sync engine failing to start. Dropbox would install, but the app never launched, no tray icon appeared, and the sync engine seemed to be stuck in a crash loop. I believe this may have caused Dropbox to replace some of my original files with empty placeholder versions. I need help determining: Whether Dropbox has older historical versions of these files stored internally. Whether a data recovery review is possible for these zero‑byte or corrupted placeholder files. Whether Dropbox can confirm if these files ever successfully uploaded before the sync engine failed. These files are extremely important to me, and I’m hoping Dropbox Support can check server‑side logs or historical versions to see if recovery is possible. Thank you for any help or escalation you can provide.
I can't open a folder shared with me; it appears grayed out on the Dropbox website.

Dropbox Basic account is over quota and completely locked
Device Dell laptop Windows 10 Dropbox App Version (if using the app) n/a Question or Issue My Dropbox Basic account is over quota and completely locked. I cannot view or delete files via: - dropbox.com/home - /deleted_files - mobile app - desktop app I am not asking for more storage at the moment. I just need temporary access to delete files and bring the account under quota so I can properly assess my current and future needs. Can a Dropbox staff member advise or escalate? Many Thanks. MW
We want to open shared links directly on the desktop app and not the website.
Hi there. Love Dropbox. I moved our whole team to it from Google Drive much to all of our delight. The one hiccup that keeps coming up (was also an issue with Drive, but would be a game changing new feature from DB) is sharing links. Our team uses the desktop app to work with files directly in finder, but we share links to files and folders on slack and in email, etc... Right now we click a link, it opens the browser as expected, we find the file path in browser and then follow that path in finder. That seems like an awful lot of work when we have a direct connection between our finder and dropbox in the app. Perhaps the website could provide a link that connects to the desktop app, opening the folder/file in finder or windows explorer. Seems like a reasonable option to me, but what do others think?Issue with communication between Dropbox web and Dropbox desktop application
Hello, I want to report issue (I believe it is bug) related to trouble with communication between your web site (https://www.dropbox.com/home) and the official Dropbox application (v240.4.8493) that normally happens on loopback port 17600: This used to work well, but for whatever reason it shows errors on try to open some file using ellipses > Open in > Desktop. Pretty often the web site cannot even detect that there is working desktop application. At the same time Dropbox desktop application seems well working - no delay in sync, etc. I made a little research what might be the reason and found out that despite desktop application does most of its work well there is significant delay (softly said) in responses to requests that website sends: Such responses have to be in borders of milliseconds (1 second is a huge delay). Above delay leads to processing timeout and error seen on first screenshot. One more additional detail: it seems that even when particular file is opened successfully at the end, Dropbox application delays it response related to the file till file gets closed. Is this normal?! It's rather BUG! Please, forward above to team responsible for Dropbox application development.Got thrown out of my Paper Document. Can't reopen it now.
Device Macbook Pro M1 Pro Operating System/Browser (if using the web) macOS12.6 Question or Issue I was working inside of a Paper document I had created. Mid typing I was thrown out of my document. A popup appeared that I lost connection. After restarting my wifi I'm still not able to get back in to the document. I tried a different browsers, private mode, VPN. I also tried opening it on my phone through the Dropbox app. No luck. Tried sharing the document with a friend and still get the same error. Is there any way the progress was atleast saved somewhere so I can acces this and make a backup?Dropbox Paper - images don't load on the web
Similiar to 3 months ago I again have a dropbox paper file that doesn't show pictures that have been uploaded. When I click on the file I get an access denied notification. Very weird as I uploaded the pictures via copy pace. The same issue occured 4 months ago documented in the following community ticket. Dropbox Paper images aren't loaded on the web | The Dropbox Community I am really wondering if dropbox paper is still a service should use if this happens again and again - maybe its better to switch to a more reliable solution such as notion.
