Where are Global Profiles saved?

Do yourself a favor and create a folder under your User.  My User is "N8GD" so I go there and create a folder named "Flex Profiles" so I have somewhere to save the profiles.  When you click on the Profiles drop down menu in Smart SDR, select the item named "Import/Export Profiles" then click on the "Export" tab at the top.  Make sure the "Select All" item is checked at the top, then click on "Export" in the lower right of the Export window.  A "Browse for Folder" window will pop up.  Scroll down until you see your User Name then click on the expand caret to reveal the folders under your User Name.  Scroll down until you find the folder named "Flex Profiles" that you created and highlight it (select by clicking on it) to make it the place to save the exported profile.  (You can actually create the "Flex Profiles" folder here by using the "Make New Folder" below.)  Anyway, once you have the newly created folder selected (highlighted), click on OK and you will see the button on the Flex Profile Export screen change to read "Exporting..."  Once that changes back to read "Export" the export has completed.  You can close the Profile and Export windows.  If you go to the "Flex Profiles" folder under your User Name, you will see two files with the date and time embedded as part of the file names.  The .cfg file contains the profiles and the .csv file contains any memories you have created/saved.  I would suspect that you could edit the .csv file with an appropriate editor (Microsoft Excel, etc.) to change or add entries and import them back to the radio ( think I've done this in the past).  Don't fiddle with the .cfg file or you will destroy the profile structure and make importing it back to the radio impossible.

One more thing.  One you've created and exported to the "Flex Profiles" folder, Smart SDR will remember that selection in the future and show it as the place to save when you do future profile exports.

Hope this helps!
