I am distributing some files on CD. Among other files i have

download.htm and
DataFile.txt

When download.htm file executes, it shoud set the path to the download file as the path for my data file and then opens the save as dialog box when user can then select storage location.

i can use some thing like

window.document.execCommand("SaveAs",true,"YourDataFile.txt");
window.close();

Here Save as dialog appears but how i can tie the box with the file on the CD?

Also execCommand is native to IE, How can i use this same in Netscape?

Thank you guys in advance
