The installation files for PC-BSD® can be downloaded for free and end with an .iso or .img.bz2 file extension. Depending upon the type of file you choose, the size will vary between ~650MB and ~3.5GB. This section will show you how to select which file to download and how to verify the downloaded file's checksum. The next section will demonstrate how to burn the file to bootable media.
If you have a slow download connection or wish to support the PC-BSD® project financially, you can purchase PC-BSD® DVDs from the .
Members of the PC-BSD® project attend many IT conferences across the globe and give out PC-BSD® DVDs at conference booths. Visiting a PC-BSD® booth is an excellent way to meet other PC-BSD® users and to get your questions answered. Check the  to see if any events are happening near you.

Selecting Which File to Download
When you go to the  page of the PC-BSD® website, you will find a number of files available for download:
- DVD: contains the full version of PC-BSD® (all system components, ports, and source); requires a DVD burner.
- USB: contains the full version of PC-BSD® (all system components, ports, and source); requires a USB memory stick or flash card.
- USB-lite: contains a stripped down version of PC-BSD® and the LXDE desktop (no system components, ports, source, or FreeBSD/TrueOS®); requires a USB memory stick or flash card.
- USB-live: contains a writable, live version of PC-BSD® running the LXDE desktop; requires a USB memory stick or flash card.
- VMware disk image: contains a pre-installed version of PC-BSD® with the GNOME, KDE, LXDE, Openbox, and XFCE desktops. See the section on Using VirtualBox for instructions on using the VMware disk image.
- VirtualBox disk: contains a pre-installed version of PC-BSD® with the GNOME, KDE, LXDE, Openbox, and XFCE desktops. See the section on Using VirtualBox for instructions on using the VirtualBox disk.
The larger the installation file size, the more components that come with that installation.
There are two versions available for each type of file: one for 32-bit (i386) systems and one for 64-bit (amd64) systems. It is important that you download a file that matches your computer's processor type (32- or 64-bit). For example, if the system is 64-bit or has more than 4GB of RAM, download the amd64 version, even if the brand is not AMD. Each media type includes the pcbsd-media-details file which identifies the release version, architecture, media type, and date of creation.
Data Integrity CheckAfter downloading the file that is correct for your architecture and installation media, it is a good idea to check that the file is exactly the same as the one on the PC-BSD® server. While downloading, a portion of the file may get damaged or lost, making the installation file unusable. Each
If you are currently using a Windows system, you can download and install the  utility. Once installed, launch the program and click the "Files" button, shown in Figure 2.4a, to browse to the location of your downloaded file.
Once the file is selected, click the green arrow to calculate the checksum. Once calculated, it will be listed in the "Checksum\State" column. The checksum is 87d28f726bd6b88c62433fddda16f089 in this example (though FastSum will capitalize the letters).
On Linux and BSD systems you can use the built-in md5 (or md5sum) command line tool to check the data integrity of the downloaded file. In this example, the file is located in the Downloads subdirectory. You should substitute the name and location of the file that you downloaded:
MD5 (Downloads/PCBSD9.1-x64-DVD.iso) = 87d28f726bd6b88c62433fddda16f089
