How do down load myfiles by IDM. Because it requide usename and pass

Hi heinhue2010,

Are you referring to Internet Download Manager? And are you trying to use it in conjunction with Acrobat.com? I'm not familiar with that utility, but to download files from Acrobat.com, you do need to log in to your account with your Adobe ID and password. If it's IDM that's prompting you for a password, you query should be directed to the folks who develop IDM.

Best,

Sara
