I want to put all my images, videos, and audio files from my camera in only one folder on my computer. What should be the name to give to that folder?
You could use media, plural of medium, meaning:
A specific kind of artistic technique or means of expression as determined by the materials used or the creative methods involved: the medium of lithography.
Did you say "from my camera"?
That is more meaningful in context than the list of file types. Calling the folder "FromMyCamera" makes more sense and can be fun, try it.
After all, Windows default folder is My Documents.
You have the option of calling the folder "Raw" if you like, except that, technically RAW is itself a file format in photography.
used to be the word, although it is now rather démodé.
