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

I also encountered the same problem, and I've deleted all the files in the 'logs', waiting for the solution...

Thanks for sharing your feedback and what worked for you, jusy.

If you come across any other issues, or if the issue returns, please let us know.

Have a great weekend!

I eventually got this resolved on my side by logging out from Dropbox by selecting Preferences -> Accounts -> Sign Out on the desktop app.

I deleted all Dropbox logs thereafter (from C:\Users\USERNAME\AppData\Local\Dropbox\logs) and shut down the computer, then restarted my computer and logged into Dropbox again. 

At some point, Dropbox renamed the old Dropbox folder to "Dropbox (Old)". I copied that to an external drive and deleted it from my hard drive to have enough space on my hard drive for the re-initialization step. Then, I selected which folders from dropbox.com should be synced again. That took about 4 days over Thanksgiving for about 1.6TB of data. Once that syncing/downloading had completed, I manually had to copy about 100 files from the "Dropbox (Old)" folder that did not sync previously. Fortunately, I made changes only in a few folders since the problems started on my side, so I was able to track down relatively quickly which files needed to be copied back into the new Dropbox folder.

Clearly, this is not the most elegant solution that required quite some computational/network resources, but as far as I can say, everything has been working fine for me in the past 4 to 5 days since the termination of these steps. No more filling up of the log folder -- and syncing to dropbox.com seems to work fine again.

Apparently, don't try to attempt this with a slow network or if you have limited upload/download capacities!

I hope this won't happen again in the future, but if someone else comes up with a different solution, it still may help others. And if someone figures out what caused this problem in the first place, that also might be helpful for others.

Just to add that the update that rolled out today has not fixed the sync being stuck or the log file pileup. For now I'll continue not using dropbox. It's been close to two weeks now.

Sorry to hear that, tyarc. When did this issue start on your computer approximately? Did you notice this after a specific update of your OS, or your Dropbox app?

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.

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.

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.

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?

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