China DOS Union

I see many places saying that format has a parameter "/autotest", I tried it, but it always prompts that it's invalid. Could it be that this parameter doesn't exist???
(Test environment: VMware---XPpro)
Has anyone used it successfully?

No one has been here??

Try using format /?. This is the most useful way.

A long time ago, the Format under DOS supported the "/autotest" parameter.
Now XP and WIN2003 do not support it, which is too unsafe~:)
And this parameter is also non-public~:)

Previously, a virus was written as a batch file that automatically formatted a certain disk,
Then encoded in BASE64, encoded and inserted into the file in EML email format,
And modify the header information (a vulnerability) of this EML email (file content),
Then import it with FOXMAIL and send it directly to the person to be received,
As long as the other party receives it or as long as this EML file is on the hard drive,
As long as it is seen (system automatic preview), it will run automatically~:)

Now anti-virus software has long prevented it. This parameter is non-public, so it is not included in the current version of the system.

Moreover, you can also encode an executable file using BASE64, and modify the EML header and part of the format, then place it on a web page. As long as someone clicks the link (pointing to this xxxx.eml extension file), the encoded executable file in this EML file will automatically run on the viewer's end. I tried it before, it was particularly fun~:) Now it doesn't work~:)

Thanks for the advice……

I tried it under pure DOS and it works,
but it's really not that useful now.
