Whilst it is possible to unlink other computers through the web interface, as slhck noted, this leaves all of your files where you don't want them. Depending on the sensitivity of your files (and how much work you want for yourself) you can:
Back up all Dropbox files locally
Delete any sensitive files from your Dropbox
Wait for the sync to remove these ...
In the web interface click repeatedly the second column header, i.e. Type until it shows Size - then you will see the size of all the items in the current folder.
In the latest version it is now a drop-down that you can click and select Size.
Go to https://www.dropbox.com/account#security and here under My devices, unlink the machines you no longer own:
Note that the computer, according to Dropbox:
will no longer stay in sync, but it will keep a copy of any file it currently has.
There's kind of a workaround. Add
at the end of the link that was shared with you. This will download the entire folder as a neatly zipped archive.
Note: This will not work with folders > 20GB or with more than 10,000 files.
As of the moment the following is possible: Go to your shared folders overview, select the folder you want to download -> a context menu appears at the top of the list with a download button. This downloads the whole folder as a zip.
The above mentioned solutions do not work anymore.
Instead, open the folder you want to download and click to select individual files, or press Ctrl+A to select all files. A row of buttons will appear above the list of files, click the Download button to download the selected files as a Zip compressed archive.
Matthew Crumley's solution works as well,...
Ubuntu One allows you to do this with a global configuration file.
On Linux, a section of the configuration file ~/.config/ubuntuone/syncdaemon.conf allows you to specify Python regular expressions to be ignored. A similar configuration file exists on other platforms.
Just to expand on Dez's answer, whilst you may not be able to change the directory that the photos are uploaded to originally, you are able to move the photos into different directories, or have directories within the Camera Uploads folder, meaning that you are still able to organise the photos as you wish. Once uploaded, according to the dropbox website:
Sign in to Dropbox. From the Dropbox webpage: go to the "Camera Uploads" folder and click on the ones you want deleted. (You can use Ctrl+A to highlight all on that page.)
Then click on "delete" in the top menu.
The Public folder was a feature in Dropbox that was later removed. It now exists only for users who've signed up before it was disabled.
For newer accounts, you can share a link to any file from any directory by clicking Share Link. You can't, however, get a direct public link from the context menu itself.

I highly recommend unclouded which is only for android phones. At the time of this writing it is a very new app but under my tests it worked perfectly(it's even, dare I say it, pretty beautiful) but to install it you have to join their group. There are really easy instructions at http://forum.xda-developers.com/android/apps-games/app-unclouded-t2825327, it ...
Answer from GitHub: Working with large files
While git is terrific for a great number of use cases, it has trouble
with large files. If you are pushing large files to GitHub, you might
want to evaluate your workflow to make sure those files are truly
necessary. Game assets, such as graphics, might be required for your
repository, while SQL ...
This happens when you have "too many" files in that folder.
From the Dropbox Help Center:
Can I download entire folders on the Dropbox website?
Note: It's not possible to use the website to download an entire folder that's over 1 GB or that has over 10,000 files. If the folder is in your account, use the Dropbox ...
For anyone looking at this question in 2014+, you can now see what is being synced (on a Mac at least—I don't know the answer for Windows, but I'm sure someone will provide that answer).
Hold Alt, and click on the Dropbox icon in menubar. This will show you what is currently being synced.
As of May 2017, the Public folder has been converted to a standard, private folder (this conversion happened for Dropbox Basic users on March 15, 2017).
The in-browser rendering of HTML files has also been/is being discontinued (see quoted paragraphs below for the exact dates). According to the pinned answer on this question, shared HTML files will be ...
Yes, the files get deleted from Dropbox as well. However, there are two possibilities to overcome this:
Set the Dropbox app to sync selectively and disable sync for that particular folder that you want to keep online, but delete its content offline.
Use the restore feature for the deleted files.
If you want to restore any deleted files, keep in mind that ...
No, "download and add to GDrive" copies the file between Google servers without downloading it to your computer. That's why it's built in to Gmail.
You can download the file to your Dropbox folder on your computer. (You could save steps by putting a Dropbox-folder shortcut where your "Save" dialog can use it. This varies by your desktop OS.) But you still ...
Here's how to edit computer names in Dropbox.
Go to Dropbox.com and log in.
Click your name in the upper right, and click Settings in the dropdown menu.
Click the Security tab near the top of the page.
Scroll down to where it says "Devices". This is a list of all your connected computers and phones and whatnot.
Double click the name of the computer you want ...
It is not as easy as Dropbox or similar services for that purpose.
The free accounts can only have public repositories, so you would also need to pay to keep your private documents on there. Dropbox and such do provide this for free.
The more public nature of Github makes me assume takedowns would be more frequent for illegal content sharing.
It is not ...
You can know this information through the Referrals Link. It would show the launcher indicating how much space you have already earned through referrals.
A couple of ways to access this link are:
Click on Getting Started Link in the sidebar.
Thereafter, the Referrals Link in point 6 which mentions Invite some friends to join Dropbox.
No. A Shared Folder is exactly that; if one person deletes a file from the Shared Folder, it is deleted for all the people for whom the folder is shared.
To do what you want, you'll need to wait for the file to finish transfering, then disconnect from the shared folder. (In the web interface, right-click the shared folder, choose "sharing options", then "...
There is an official version (for Android) here:
Why does the Dropbox Android app request access to my contacts?
The Android app uses your contacts to provide features that make it
easier for you to use Dropbox, including sharing with friends without
having to remember their contact info. For example, when you share
files and photos, Dropbox ...
One service called Zapier (disclaimer, I'm a cofounder) offers exactly this (plus a lot more), I invite you to check it out. We have the ability to send Basecamp Attachment to Dropbox and also Sync New Dropbox File to Basecamp.
It looks a lot like this:
If you have any questions about how we do this, I am more than happy to answer them: just email me at ...
Dropbox does do block-level sync, according to this answer to a ServerFault question.
The blocks in question are 4MB, apparently. Whether your idea of a loopback filesystem / disk image to dump all the 20K files into a single file for Dropbox syncing would speed up Dropbox sync would depend on the speed of your internet connection - you would be trading ...
