My C drive is almost full

A serious clean up would be useful as well as moving all of your DATA files to an alternate drive.

Same way you save to any drive assuming your D Drive is a partition on your hard drive. When you choose File>Save, you specify a folder on the other drive.

However, for many people their D drive is an optical (DVD, CD) drive so you generally don't save to that.

So to answer we need to know more about your system.

Buy an External USB Drive and move all your downloaded and saved stuff over there (cut and paste a little at a time). Use your C drive only for the OS and programs you install (I install all my games to D\Program Files, a folder I created for that purpose). Most download applications have an options section where you can tell it where to download to. I like to make a folder on my D or external drive called 0Temp. The 0 ensures its at the top of the drive so its easy to find, and from there I split stuff up into specific folders like Utilities > Audio or Video > or Security (antivirus) etc.

bbretreds does not find this helpful : when I click on"file" the "save" option does not allow a choice of where to save

If you are saving a NEW file, then you WILL get a Dialog box allowing you to choose a drive and folder. If you are saving an existing file, then you will have to use Save As.

Your missing an important point ScottGem. If his C drive is full he has to deal with that first since all downloads go to C > Temp first and then get transferred to where he wants from there. If there is no room on C where the Local > Temp files are, he's going to have trouble no matter how he saves.
