Hi @"sz999", sorry to hear you're having issues with this. Can you please send us a screenshot of the exact error you're getting, omitting any personal information if possible? Have you cleared your browser's and the app's cache at all lately? Were you ever able to open the file normally?

Thanks for the additional information and the screenshots too @"avadoodle" Since you're able to view those files normally on our website, I'm starting to think that this might be an issue due to a missing codec from your (and your boyfriend's) device. Have you maybe tried downloading a codec pack for your media players to…

Hey @"Allan Pole", sorry if this wasn't clear, but there might be other 3rd party apps that could be interfering here, apart from Google Drive or One Drive that is. Do you have any of those? Also, can you clarify if you upgraded your device's OS lately and if you ever had the syncing icons normally on this device? Could…

Hey @"jovk", sorry to jump in here, but do you happen to be on the Basic plan? If so, have you made sure that you have no more than 3 devices connected to your account, including your Android device, as there's a limit you might be hitting? If that's not the case, please let us know here and we'll reach out via email to…

Hey @"Rinconman", thanks for posting on our Community! For starters, note that even though you can't completely opt out of this upgrade, you can keep postponing it until you're completely ready to move forward. As for the advantage this offers, the new Dropbox Business organizes your team’s content into a consistent folder…

Hey @"Magill3179" & @"Stefanwork" - thank you both for your reports. Since you've already done some troubleshooting, as a last troubleshooting step could you try another wifi network and let us know if you still get the same error? Thanks!

Could you temporarily disable any antivirus or firewall you may have running on your computer and let us know if you're still getting the same error @"jen1147"?

Hey @"TBat", sorry to jump in here, but can you clarify your computer's exact OS version? Have you updated it recently or did you install any 3rd party apps perhaps?

Hey @"emsilver523", sorry to jump in, but have you ever tried clearing the app's cache when you notice this? If this comes up again, please send us a screenshot of the page you get stuck on, and we'll take it from there. Thanks!

Hey @"avadoodle", could you maybe send us a screenshot of the error or blank page you're getting when trying to preview those files on your computer? Did you try another 3rd party app to open them by any chance?

Hey @"Allan Pole", sorry to jump in, but could you clarify the desktop app's status as shown in your menu bar? Is it up to date or still syncing? If it's up to date, can you check if the information from this discussion helps in your case as well? 

Hi @"FCBC", sorry to hear about this. Could you clear your browser's cache and/or try another browser? If you do and still get the same results, please send us a screenshot so that we can have a visual too. Thanks!

Hey @"Oma5", could you post a screenshot of the exact error you've been getting?

Hey @"avadoodle", sorry to hear you're having issues with this. Can you please go through the steps you take to export those files to your devices and, if possible, send us a screenshot of the error you get when trying to preview them locally? This will help us assist further.

Hey @"mstroz", sorry to hear you're having issues with this. Can you please let me know how you moved your folders and also send me a screenshot of the app's exact status as shown in your system tray? Is it up to date or still syncing? How does your folder structure look like on our website? Do you see those actions in…

Do you remember how you uploaded them in the first place, Leanne? Also, were you ever able to preview those files normally on our website? Can you preview them in your Photos tab? Have you perhaps tried to open those files with another program on your computer? Can you download a sample file from the problematic ones and…

Hey @"ElSid1", sorry to jump in here. I just wanted to check if you're still getting the same error if it was resolved for you after all. Let us know and we'll take it from there!

Hey @"maybrit19", could you clarify what exactly is troubling you so that we can assist further?

Hey @"pamallama", sorry to hear you're having issues with this. Could you please try clearing your browser's cache or another browser and let me know if this persists? If it does, I'd appreciate a screenshot of the exact error you've been getting. Thanks!

Hey @"Glebich", just to make sure we're on the same page, could you send us a screenshot of what you're referring to?

Hi @"Runnerdad", thanks for joining our Community! To directly get to the chase, you're spot on on your assumption. You should copy or move any files or folders that want to be backed up to Dropbox into one of the OS folders that are supported (i.e. Desktop, Downloads and Documents) and then enable the computer backup…

Hey @"alanS", sorry to jump in here, but I just wanted to mention that this space might be taken up by the cache folder that Dropbox creates on your computer. If the desktop app has finished syncing and it's 'up to date' in your menu bar, you could try deleting it to free up some hard drive space. Let me know if this…

Hey @"Myshewasyar", have you tried another browser at all since you first noticed this issue? If you did and this persists, please send us a full-page screenshot of the blank page you're getting. Thanks!

Hey @"jen1147", sorry to hear about this. Could you perform a clean, advanced reinstall and let us know how it goes? If you happen to be on the Basic plan, make sure to have less than 3 devices connected to your account. 

Hey @"SuzanneT1", sorry to hear you're having issues with this. Can you send us a screenshot of the error you're getting and also clarify what kind of files you're trying to delete and from where exactly? Thanks so much!

Hey @"hellomoto", sorry to jump in here, but could you try renaming the files and try to move them anew? Do you still get the same errors?

I'm glad to hear it's sorted now @"amelling" See you around and take care!

Hey @"lauram73", sorry to hear you're having issues with this. Could you please let us know the app's status as shown in your menu bar at the moment? If you could also send us a screenshot of the options you're getting, I'd appreciate it. Thanks!

Hey @"izaguirres", sorry to hear you're having issues with this. Could you let us know the app's status as shown in your menu bar? Is it 'up to date' or still syncing? Did you install the desktop app with admin privileges in the first place? Any additional information or screenshots would be much appreciated. 

Could you try clearing your browser's cache or another browser to download the installer @"Davide P"? Just make sure to do it with admin privileges as outlined here.
