We recommend creating a CAD Standards folder to store all your important CAD- and Land F/X-related backups. We also recommend creating and saving an AutoCAD profile, which will keep your AutoCAD interface looking exactly the way you want it to look, whenever you open CAD. Once you have located acad.cuix, we suggest making a copy of it and saving that copy in the location of your choice. In the event that you need to use the backup version of acad.cuix, you'll need to put it back into this folder. We recommend pasting this folder location into a word-processing or note-taking document and saving that document in the same location where you save the file acad.cuix. You'll be brought to the folder that contains the file acad.cuix. (You can paste by pressing Control + V.) Then press Enter. Click within the address bar (Windows 7) or the Quick Access bar (Windows 10), and paste the folder path you just copied.
