Hidden Dropbox logs folder is stuck, continually growing bigger, now beyond 300GB

Hi jusy, thanks for the details. It might be worth getting in contact with the support team to see what could be causing this.

An update from me... 

Still no solution, uninstalled, cleaned registry, rebooted, reinstalled and issue remains.

So, although Dropbox does not support logs being stored elsewhere (why not?), I used a Symbolic Link from:
C:\Users\[username]\AppData\Local\Dropbox\Logs
to:
E:\DropBox-Symlinked-Logs\

That at least stops me running out of space, my C: drive is a SAMSUNG PRO PCIe 4.0 M.2
My E: drive is a good old SSD with 4TB

And 24hrs later, 427GB of space used with 433,235 log files.
To me, the bug is Dropbox not clearing up. I'm now fully synchronised and Dropbox no longer using 20% of both CPU and memory which it's done all this time.

Why so many logs, I wouldn't mind but I've only got 363GB of files on the hard drive, 670GB in total (so half online only).

For now, I'll keep the Symlink in place, try a reboot and if that doesn't clean the logs, manually delete in the hope it doesn't do it all over again!

Thanks for keeping us in the loop on this exouk - much appreciated.

I just wanted to add that if the reboot doesn't improve matters, you can also try clearing your cache folder.

Let us know of any updates!

Walter, thank you.
I'm glad to report that deleting .dropbox.cache after I let it fully sync, and a reboot has finally fixed the issue. 
I think part of the issue was DB could not fully sync due to running out of HD space.
I hope some of the details on this post help others.

All the best.

Hi exouk​, thanks for the info here!

Happy to see that your issue is now resolved! If you need something else, please let me know and I will be more than happy to help every step of the way. 😇

Just registering for updates as I'm also experiencing this. It's showstopping so I hope dropbox will address this asap

Unfortunately no success on my side. I stopped dropbox, deleted all files and folders in .dropbox.cache, rebooted, and restarted dropbox.

It created 6 new subdirectories in .dropbox.cache. They remained empty so far for about 2 days, but the problem still exists on my side: It  still tries to download over 700,000 files. That number is exactly the same as before. As far as I can see in my log files, very little has been downloaded (if anything at all).

dropbox itself got updated to version 237.4.5655 on my side. Other than that, no obvious change. The log folder still gets filled, but eventually gets deleted after about 1 hour / 10,000 files during daytime (but not when no other processes are running at night).

I should mention that no new files or modified files have been synced since the start of this issue, i.e., for about 12 days now on my side.

I am wondering: What are those files in Users/[UserID]/AppData/Local/Dropbox/instancex (where x=3 on my side). Those are pretty big data base files and get updated regularly. I do not manually want to mess with them, but could they contain what dropbox tries to download (or upload) unsuccessfully - and could some of them be modified or deleted?

No change here either. Dropbox will not sync. Even when syncing is paused, it creates 100's of Gb of logs a day leading to data loss on my system drive. After running for an hour or so it also just crashes. I have to stop using the app until this is resolved, despite paying hundreds a year.

Hi everyone, if you're still experiencing these issues, please could you contact the support team for them to look into this in more detail.

I'm also having this problem, log files are taking up my entire C drive causing my entire computer problems. I can temporarily resolve it by quitting dropbox desktop and deleting the logs but then my files don't get backed up! Very frustrating.
