    Script a .js file that will then be referenced by a .hta file - you may need
    to accept the security warning once but after that - Bob's your uncle. If
    you reduce your IE security then you may get away with no dialog - not sure.
    A .hta has FSO file access to the local machine [I think] so you could then
    load the documents into a frame and save from there (not entirely sure how
    at present). Anyone know if a framed document has a binarycontent property
    that can be read to stream to disk?
    Is this not feasible with an authenticated FTP download? Most webservers /
    hosts will allow an FTP access to the website? Perhaps the documents are
    stored outside the website?
    My own opinion is that you should communicate with the webserver hosts and
    get them to set up an FTP login for you to access the documents or even pay
    them to ZIP or RAR them for you so you can download them as a single unit
    using a download manager that wouldn't hog your internet bandwidth for hours
    on end (depends on how much content).

    Hi,

    I need to pull a ton of files off of a webserver so we can migrate the
    content to a new environment. There is metadata attached to each file, but
    that's not the problem.

    I have a VBScript file that will open an instance of IE, login through the
    tool's interface, and then grab a list of all projects (roughly 50). Each
    project has anywhere from 0-100 files that I need to grab and store in a
    local directory.

    I have the code ready for navigating down the tree, but my problem is when
    I'm trying to grab the file that the site is referring to by a link. The
    file url is:
    http://stagingserver/DCS/servlet/com.merant.wcm.engines.DownloadFile?folder=Cons_Ando_Pub&Cons_Ando_Pub_method=FS&fileID=1379

    If I open a new browser and copy/paste this URL, I get an HTTP 500 error
    with all types of Java errors. I'm assuming this is because I haven't
    authenticated in the new browser window. If I click on the link after I
    authenticate, then I get to the file successfully. I'm assuming that I have
    to launch this link from inside the instance of IE that I'm navigating down,
    since that session has been authenticated.

    I was trying to use MS's XMLHTTP to grab the file (see the following code
    that should grab the file):
    set oHTTP = CreateObject("msxml2.XMLHTTP")
    oHTTP.open "GET", sSrcUrl, False
    oHTTP.send

    I need to be able to take this URL, and save the resulting file into a
    specific directory under a specific filename. Can anyone help me?

    Thank you!
