The eMMC (internal memory) on Bela is 4GB, and that has to contain all the operating system and programs (leaving about 1GB available), so your files will not fit. If your Bela came with an SD card, the SD card itself is probably at least 8GB, but the actual size of the partition will still be 4GB, so first thing you will need to resize the partition on the SD card.

putty, and set it to connect to the board, which has hostname:

root. There is no password needed. Once you are displayed the prompt from the board, i.e.:
root@bela #, then you are ready to start following the instructions here are the instruction to do it.
Last, copying the files: open a terminal on your computer and use
cd to browse to the folder containing the files you want to copy. From there, you can use the
pscp command to copy the files to the board:
pscp -r *.wav email@example.com:
where I assume that all of your files are called "something.wav".
