NOTE: The other option for uploading files is to click on the “Attach files to this message” link that you’ll see just below the box you type in when responding to a Client Section message.
To upload multiple files you should add them to a folder and then zip them before you upload them to the Client Section. Zipping a file creates a compressed version of the file that is considerably smaller than the original. Also, by zipping a folder of files, you can upload or download them all at once to our client section, which saves time. Here’s how to do this:
On PCs:
There are more instructions on zip files on the Microsoft office website.
NOTE: If your computer doesn’t have a program to compress files, “Winzip”: is a popular one that you can download a trial version of.
On Macs:
If your zipped folder is larger than 10 MB, then they won’t upload to the client section. In this case you could divide your files into folders that are smaller than 10 MB or your could use an online ftp program.
The easiest option for this would be to go to “Yousendit.com” (http://www.yousendit.com):
