-     * request for a given file will be at least `ceil(n / 3) * 4` bytes, where n is the file size in bytes. This is the minimum size because there might also
-     * be other parameters in the request. On average the multiplier appears to be about 1.5, so when checking whether the file will exceed the file size limit when
-     * uploading a file we just divide the size of the file by this number. The alternative would be to actually check the size of the HTTP request but that's only
