Following on from what CrazyaboutX said...
If the file is less than 300MB you can upload it with sendspace but if it's larger the file can be split into separate parts by doing the follwing:
1) Right-click on the file and select 'Add to archive' from the drop-down menu.
2) Where it says 'Split into volumes, bytes' select 'Zip100' from the drop-down menu.
3) This should split the file into different parts.
4) Go to
www.sendspace.com and click on 'Multiple file uploader' and add the files you separated.
