I've had similar results with LTSpice, by default it tosses the simulations
results to the current working directory. Fortunately, you can tell LTSpice
to use a specific temp folder for simulation results.

In the interest of presenting alternatives -- I dumped Dropbox a while
back, due to their increasingly invasive 'privacy' policies.

A good alternative for me has been Sync: https://www.sync.com/

Their 'Free' package includes 5GB -- More than I would ever possibly
use for an online sharing account. ;-)

Keep the peace(es).

[Didier Juges]

Yes, I noticed that before.
I have a number of tools that don't like running off a Dropbox folder,
including several software development tools for starter. Too many files
opened at the same time.
Don't assume that because it looks like a normal folder, it works like one,
even though for many things, it does work remarkably well.

Yep, I can see where that would be an issue  Use an un-synced
directory/folder and them back up to dropbox off-air if required...  :)

[time-nuts] Dropbox is cool, but...

[John Ackermann N8UR]

So I was clever and decided to log some PPS data to a folder within my 
"Dropbox" folder.  Strange results followed... the whole system just 
bogged down, and even fairly slow serial data dropped characters.


It turns out that the culprit was the Dropbox daemon continuously trying 
to sync the file as it changed every second.  It didn't manifest as CPU 
overload or anything obvious; the problem was apparently thrashing in 
the I/O system.  Once I started dumping the data to a "normal" 
directory, the problem went away.  (This was on Linux, by the way).


So, a lesson learned -- don't stream unbuffered data, even at a low 
rate, into a sync'd folder!
