Hello. I successfully forgot my TrueCrypt password. Now I know as far as recovering, its impossible. But my question is, is there a way to identify if TrueCrypt is protected with key file or not. I hope not, but I also hope yes, because I also forgot if I used key file. I know the question is too far fetched and I answered it already, but here's hopping....

Please note that theirs forum is locked from posting.

Motherboard: ASUS P8Z68-V LX; Processor: Intel i5 2500k; RAM 24GB: CORSAIR XMS3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800); CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800); Video Card: MSI AMD Radeon RX 470 Gaming X 4G GDDR5; Power Supply: OCZ ZS Series 650W 80PLUS Bronze High Performance Power Supply; Multi-card reader: Nippon Labs Delux 3.5" Internal All In One Card Reader/Writer with USB2.0 & eSATA Ports Model ICR-BB. Optical 1: LG GH22NS90; Optical 2:  ASUS BW-12B1ST; Fans: 3x80mm, CPU Cooling: XIGMATEK LOKI SD963. So there are total of 6 fans.

No, there is no way to find out if a keyfile is used or not. And keyfiles are used together with a password, unless you leave the password field empty when you create the volume.
So even if you have used a keyfile and find it back, you still need the password too.

Now, from what you describe, I suppose this is a file container, not system disk encryption? Because TrueCrypt forces you to create a rescue disk with system disk encryption.

Yes. It is a container. Is there a software that can brute force with a specific set of possibilities? I have several passwords in mind. Its a matter of punching those through and combining them with all the possible keyfiles?

Sorry, but you'll have to find out on your own, we don't discuss password cracking here. Even if I understand that it is a legit case.
