TurboTax Desktop Question

Hello all.

This is something that has always bugged me, but why does TT desktop save 2 copies of my 

Tax Return.tax2024 file?

One copy has one ~ at the beginning of the file name, and the other has 2 ~'s, or occasionally there is no ~ at the beginning.

Normally one copy will be a few KB's larger than the other one, and the time stamp will be a couple minutes apart.

This has "always" happened since I've been using TT Desktop (or at least as far back as I can remember).

I'm using both TT Deluxe for my personal taxes and TT Business for a Trust, and it happens in both.

 

Thanks.
