Dropbox freezes and crashes my file explorer.

1. Q. How many files am I syncing? A. Many files (~ 1.6 TB); however, these files are mostly "Online-Only". Only a few folders are actually on my drive based on when I use them.

2. Q. Are you having problems with both folders? A. Yes, I'm having issues with both my Business files and my Personal files on Dropbox. The same lagging issue is happening with both. Both accounts are linked to my account and synced to my computer. My personal Dropbox files are all on my computer but my Business files are "Online-Only".

3. Q. What’s the current syncing status of the Dropbox app? A. "Up to date"

4. Q. Are you noticing the same behavior if you quit the app, as well? A. Yes, I tried quitting Dropbox and I'm experiencing the same issues.

Thanks for your help!

Thanks for the extra info, dhannah! 

1. I’d like you to right click on both your Dropbox folders, go to Properties, and send me a screenshot of the next window you’ll see on your screen. 
2. If the Dropbox app isn’t running, but the same issue persists, then there may be something else going on. Can you please try to open a few other folders on your device (irrelevant to Dropbox), which also contain a lot of files, and let me know if they load right away?

1. See screenshots below:

2. The Dropbox folders are the only ones that are slow. If I click on folders under my non-Dropbox folders, there is no lag or issues.

Thanks

Thanks for these screenshots! Do you happen to have any antivirus/firewall/VPN activated on your computer? 

If yes, I’d like you to disable it for a little bit, and test this again. Is the Dropbox folder opening normally now?

I do have an antivirus program (Symantec Endpoint Protection); however, when I disable it as you suggested, there is no difference in how quickly I can navigate through the Dropbox folders.

Furthermore, these issues started happening about 2 months ago (that I noticed) and I haven't changed anything security wise at that time.

Hmm, I see. Are you still having trouble with the Windows update shown in your first screenshot?

What if you uninstall the Dropbox app, while your antivirus is still off, restart your computer, and then install the Dropbox app again?

Thanks Nancy.

Before I try that, I'd like to mention that when I am trying to save a file (either through Microsoft word or my pdf editors or any other application) my navigation through Dropbox is seamless and for some reason I'm not having those same Dropbox issues. It's only when I'm navigating through Windows Explorer.

Does that give you any additional ideas? If not, I can try what you suggested above.

Thanks

Thanks for letting me know about that! It’s not necessary that everything related to Dropbox will be lagging, in this case. If you try the steps I sent you above though, and the issue still persists, then I’m happy to investigate this further and isolate the issue more.

I have the exact same problem. Navigating my local Dropbox folders on Windows 10 is painfully slow (using arrow keys to scroll through files, etc). It is as though I'm navigating an online cloud interface, not a local directory. This started just a couple of weeks ago and has really degraded the usability of Dropbox.

Hi there William F.5 - sorry to hear about this.

Can you please clarify you're device's exact OS version and the version and status of the Dropbox desktop app as shown in your system tray?

Did you reboot your computer since you first noticed this?
