Dropbox not updating on other computers
Because a file with the same basic name and properties already existed, Dropbox wasn’t able to create the new file on our end.
This folder holds gigabytes of miscellaneous data collected during file downloads and sync processes in a series of smaller files with crazy alphanumeric names.
If you’re still experiencing issues, you may want to investigate further to see if the ports Dropbox is using are in conflict with other applications and/or systems on your network.
You should be able to run Dropbox on a dozen or more systems simultaneously without any port problems, though your router may be blocking the application from passing through should it detect a problem.
The vast majority of home networks out there don’t run through a proxy.
This is usually a tool implemented by enterprise-level IT.
