TurboTax for Windows Creates Cache Folder and Debug File in Tax File Save Location
You may have noticed a couple files located in the same folder as your .tax file that you saved. There is a file folder called Cache and a file called Debug saved there.
These files are TurboTax configuration files, and pose no harm to your system or your tax file. You shouldn't experience any problems if you accidentally delete them either, we just wanted to make sure you knew they were ours and there is no issue caused by them.
