In which folder XSPIM (Ubuntu 10.04) save the txt files?

Question

Hello mates from StackOverflow.

I am getting some problems on finding in which folder xspim saves a txt file... for example I tried this code locate at the bottom of this page:

Btw, I only can create the txt if I execute xspim as root, because without permissions it cannot write on the disk, and xspim returns a negative value on the $v0 register.

Well after creating the txt file and writting something on it, then I can open it without any problems at all as well as I can read the contents of it.

But even with the file created I can't find it! I searched for the file using the File Search but without success. Anybody knows where the txt file went?

I appreciate any help. Thank you in advance. Cheers
