• modifying the data file to delete the first file preview data to reduce the file size of the data file;
• and
• storing the modified data file to a storage medium of the storage device;
• and
• in response to receiving a request for the data file from the host:
• retrieving the modified data file from the storage medium;
• generating second file preview data corresponding to the first file preview data;
