These are files containing the installer and other software for the Debian GNU/Linux operating system. The files in this directory are designed to work on both 32-bit and 64-bit PCs (i386 and amd64).
The files here are complete ISO images, ready to use.
Once you have downloaded all the ISO images you want, you will typically need to write them to installation media.
The images described here are sized to be written to writeable DVD media at a minimum, but may be written to larger media if needed. For extra convenience, these images may also be written directly to a USB stick. So long as your computer will boot directly from that USB stick, it should start the Debian installer that way. The first DVD in this set is also deliberately limited in size so it should fit on a standard-sized 4GB USB stick.
update files here are extra convenience files
for people updating from previous versions of Debian. If you are
installing fresh, you may safely ignore
There are files here (MD5SUMS, SHA1SUMS, etc.) which contain checksums of the images. These checksum files are also signed - see MD5SUMS.sign, SHA1SUMS.sign, etc. Once you've downloaded an image, you can check:
For more information about how to do these steps, read the verification guide.
See the Debian CD FAQ for lots more information about Debian CDs and installation.
