add nohash prefetch item

This command downloads a file without verifying the file's hash. This is insecure and not recommended, but it might be necessary in some cases.

It must be between a begin prefetch block and an end prefetch block command.

Unlike add prefetch item, it can only specify one download and relevance substitution is not allowed within the arguments of this command.

add nohash prefetch item [name=<name>] [size=<size>] url=<url>


  • name is an optional file name for the download. If no name is specified, it will be automatically determined from the URL.
  • size is an optional file size.
  • url is the URL of the file.

The arguments may be in any order, but unrecognized arguments will generate a syntax error.

Note: The downloaded file can be cached only once per action.


Download and run a file as insecure.exe without verifying its hash.

begin prefetch block
add nohash prefetch item name=insecure.exe url=
end prefetch block
wait {download path "insecure.exe"}
