You can now send files or large file attachments by just using the file URL directly to "the cloud" without downloading to your computer or mobile device. At present, "the cloud" can be your e-mail account or your DropBox account. You can even send large files within 10 seconds to a minute.
It's called Side Cloud Load.
Transfer Files From Host URL Directly To Your DropBox, Email (link)
The steps to using Side Cloud Load are so easy:
1 Go to the Side Cloud Load website (link).
2 On the first blank space, paste the file URL or upload the file.
3 On the second space, select the cloud service, whether e-mail or DropBox.
4 On the third space, enter the receiver’s e-mail address. If you’re sending the file to your e-mail account, then enter your e-mail address.
5 On the last space, enter the file name.
6 After filling all field spaces, click on the "sideload it" button.
7 Don’t forget to fill in the security code before sending the file.
When receiving using the e-mail, check the spam box as the filter might have mistaken the sent file as spam.
At present, the "large file" limit stands at 25MB. Hopefully this limit can be increased in the future. There are now more than 2,000 users of Side Cloud Load. URL Droplet (link) is also a good alternative if Sound Cloud Load doesn't work for you.
