In order to inhibit the unauthorised distribution of large volumes of electronic data, selected sensitive files are loaded with padding data to increase the size of the files such that file transfer, distribution, or downloading to removable media storage devices is more cumbersome or more easily identifiable. A file loading system comprises a datastore for storing a plurality of data files 302 where each of the plurality of data files includes information; and a processor arranged to access the data files and load a data pad 304 into one or more files to increase their size. The padding may be added only when a transfer operation is initiated so that other operations, such as opening the file for editing, are not hindered. The amount of padding data added to the files may depend on factors including the data transfer rate of a connected network and the supported data capacity of the removable media devices. The padding may be interleaved throughout the file, optionally in a pattern which can be checked to confirm authenticity of the file. |
