    - blobAppendValue()
      Works like blobSetValue(), but the value is appended to the blob.
    - blobGetValue()
      Reads "value" from byte offset "offset" with "len" bytes from blob.
    - bloblen()
      The function returns the length of a blob in bytes.
    - blobRead()
      The function blobRead() reads the content of a file into a blob variable.
    - blobSetValue()
      Writes "value" from byte position "offset" with "len" bytes to the blob.
    - blobWrite()
      The function blobWrite writes the content of a blob variable into a file.
    - blobZero()
      Sets blob length to len bytes and initialize the blob with "0".
    - byteSizeToString()
      Converts a filesize in bytes to a string (for example, with getFileSize()).
