LiveSpace gives you the possibility to both upload files from the computer on which you are working, and use the files you keep in the Dropbox (http://www.dropbox.com). In the first case (uploading from disk) selected files are placed on the LiveSpace server and you can access them at any time. In the second case (Dropbox) only a link to the file from Dropbox is stored in LiveSpace, so if you delete a file from Dropbox, it will be not longer available in LiveSpace, too.
Adding files on the wall (with the possibility to choose a file from your local disk or Dropbox):
Selecting the second option pops up a new window. You will be asked to log in to Dropbox (LiveSpace does not store the access data to Dropbox, so user authentication is done inside the Dropbox):
After logging in, you will see a list of folders and files. You can choose one file only or several files at the same time. After pointing them, click the Select button to confirm your selection:
The selected files are now linked to LiveSpace. They will appear on the wall after adding a new post with files.
