The file size is smaller in that it takes up less memory than lets say .tiff images.
The -compressed option forces Wusage to produce compressed reports. See the Optimization section of the manual for more information. The -d option MUST be preceded by the -c option and a configuration file name, or the -a option and an account name. When the -d option is present, Wusage removes all existing reports and work-in-progress information, except for the DNS cache. This option must follow, not precede, the -c or -a option and its argument.
Computer files can be compressed so they take up less memory. This makes them faster to send over the Internet. There are many different file compression file formats including GIF and JPEG.
files are those that have been put through a process to reduce their size. Image files such as GIF, PNG and JPEG are compressed before they are sent on the Internet to save download time.
Data files available for download from the Internet are typically compacted in order to save server space and reduce transfer times. Typical file extensions for compressed files include zip (DOS/Windows) and tar (UNIX).
Many files on the Internet are compressed--this reduces the space taken up by a file and makes transmission over the Internet faster. The client must then have software able to decompress the file.
