how to test files you've downloaded

now this is very easy

if you look around the window where you downloaded a file from you see an MD5 (yes that's the built in tester file, i recommend saving MD5 in the same location of the download, now that you have the MD5 (probably named MD5.sum)

it's called this because it is actually called an MD5 checksum

it very easy to use, but it actually checks the original integrity or the original file, and you actually compare the output of a command with the contents of the MD5 you also downloaded, so, at the command prompt (Windows) or console (Linux) type md5sum {-options} {file}, so lets assume we've downloaded a .ISO file called KNOPPIX_V5.1.1CD-2007-01-04-EN.iso the command to check the file is:
Code:
md5sum KNOPPIX_V5.1.1CD-2007-01-04-EN.iso
and the MD5 checksum you downloaded is actually a text file so open it with your fav text editor and varyify the checksum match the output of the command exacly, if it does match :good: if it doesn't match you need to redownload the file
