To access your default Windows TEMP folder, you can either use Windows Explorer to go to the following folder:
C:\Users\YourNameHere\appdata\local\temp\
or Click Start menu (Windows) then Run: In the Run dialog box, enter %TEMP% and click OK.
You can however set up AutoCAD/LT to use any other folder you may have or wish to create: this can me one single folder on your local PC that you can access quickly (in the screenshot example below I use a folder called TEMP located on my computer's C primary drive).
Or you can create multiple folders, one for each of the five categories in the screenshot above, or just one additional folder for your Autosave files for example. After you create one or ore of these folders in Windows Explorer, open OPTIONS command's FILES tab, select the entry you wish to change, select the folder name, tap the BROWSE button and browse to the new folder to select it.Just follow the sequence of numbers in the screenshot below.
