Make stalled synchronisation work
You’ll usually find it most convenient to set Dropbox to automatically download any new files to your Dropbox folder on your Desktop. If Dropbox starts to sync files so they appear in this folder but the process fails to complete, the Desktop version of Dropbox may be corrupted.
A spinning Dropbox icon in your notification area indicates that it’s attempting to synchronise your files.
Reinstalling your Desktop version of Dropbox (www.dropbox.com/install) should fix the problem.
Fix problems syncing Dropbox files to your PC by reinstalling the Dropbox Desktop version.
Stop security settings blocking Dropbox syncing
Some anti-virus software, notably Panda and NOD32, can block Dropbox’s attempts at syncing, while PC Tune-Up uninstalls it as part of its optimisation process. Contact Panda (www.snipca.com/10163) or ESET customer support (www.snipca.com/10164) to ask them to unblock Dropbox on your account. It’s also worth whitclisting Dropbox in your browser’s security settings.
Make missing files sync across a number of computers
The whole point of Dropbox is that you can access any file stored in your Dropbox account from any computer or device, providing you’re logged in. Sometimes, files may not appear in your Dropbox folder when they should. To fix this, first check whether the missing file has been uploaded to your online version of Dropbox. Log into your account to see if the file is there. If it isn’t, go to the bad files page at www.dropbox.com/bad_ files, check. If your missing files appear here click the option ‘To learn why these files are incompatible with certain operating systems’. Invalid characters in a file name can often prevent Dropbox from syncing that file to your local folder. If you can access the original file, amend the file name to exclude any characters that prevent the file syncing, then upload it again.
Stop Dropbox slowing down your computer
Dropbox automatically indexes the hies and folders in your account to make sure everything is up to date, as well as to check how much storage you’re using. If your Dropbox account is full of large, gigabyte- sapping hies, this indexing process can slow down your computer during other tasks. Dropbox has recently introduced a hx for this annoying problem, but you need to update to the latest version of Dropbox (currently 2.2.13) to take advantage.
Access Dropbox files offline on your phone or tablet
To save space on your phone or tablet, Dropbox only synchronises hies to it when requested to. The rest of the time the Dropbox app displays a list of your hies, but you won’t be able to access them without a web connection. To make a hie available offline, swipe over it to reveal the actions list, then tap the star to mark it as a Favorite.
Stop Dropbox files being hacked
Files you store online in a Dropbox account are automatically encrypted using 256bit AES protection. Dropbox will only remove this encryption if it’s legally compelled to give your hies to the UK or US governments. This is a pretty unlikely scenario, but malware that intercepts your uploads is a bigger threat. Free tools such as Boxcryptor (www.boxcryptor.com) can encrypt your documents before you upload them, while still letting you view their contents. Tick ‘Disable Encrypting File System (EFS)’ when you install Boxcryptor and allow the EldoS encryption engine to install. Once you’ve created a Boxcryptor account, right-click a hie or folder to encrypt it, then upload it as normal for Dropbox. While it’s sensible to add an extra layer of security to your hies, Dropbox won’t be able to salvage them if your account becomes corrupted. This is because Dropbox won’t have access to the encryption tools you used.
