Audacity 3.24

I do a lot of post production work for a local theater group. My computer is a Dell desktop with a AMD Ryzen 7 1700 Eight-Core Processor 3.00 GHz and 32 gb of memory. I’m trying to save my work on a drive that has 2tb available and I keep getting “Your drive is full”. So I tried to save the file to another drive that has 12tb available and I got the same message. The only way I was able to exit out of the program was to go to the task manager and stop the process…
Any Ideas ??

What format is the drive? FAT format is not supported by Audacity 3.x.
