To many, IDM does not support 'resume download' from file sharing site unless you use premium account of that file sharing site.
Internet download Manager can download files from different file sharing site, capture download, re-capture the download address if the Download does not finished, and also resume failed download.
IDM works with Megaupload, Rapidshare, Filesonic, Wupload, Uploading, Hotfile and other filesharing sites
In the Internet Download Manager
right click on the file name you want to resume
click on Refresh download Address, a message will pop up
Your browser will then load the download page
click on the download link and IDM captures the address (a message will pop up)
If IDM cannot capture the address, right click on the download address, click copy link address to copy the address to clipboard, IDM then automatically copy the download address.
then Click resume to resume the download
