How to Enable Where to Save Files in Chrome | How to Make Chrome Save Files to a Different Folder
When you download files using the Google Chrome web browser, Chrome saves those files to a specific file folder. You can change this default download location to organize your downloads, free up space on your hard drive, or redirect downloaded files to an online storage service, such as Dropbox. You can also set Chrome to prompt you for a download location each time you download a file. To change Chrome's default download location:
Open Chrome and select the menu icon (the three vertical dots). Then choose Settings.
Select Advanced in the left pane.
