To test if a file exists, you can use UTL_FILE.fGetAttr. Docs

For example:

DECLARE
  l_file_exists BOOLEAN;
  l_file_len    NUMBER;
  l_blocksize   BINARY_INTEGER;
BEGIN
  utl_file.fgetattr(
    location    => 'MYDIRECTORY',
    filename    => 'myfilename.ext',
    fexists     => l_file_exists,
    file_length => l_file_len,
    block_size  => l_blocksize);
  IF l_file_exists THEN
    dbms_output.put_line('File found, size=' || l_file_len);
  ELSE
    dbms_output.put_line('File not found.');
  END IF;
END;

To rename a file, you can use UTL_FILE.fRename. Docs

For example:

BEGIN
  UTL_FILE.FRENAME (
    src_location  => 'FROMDIRECTORY',
    src_filename  => 'filename.ext', 
    dest_location => 'TODIRECTORY',
    dest_filename => 'filename.ext',
    overwrite     => FALSE);
END;
