Batch file to unblock files copied from internet

Question

When we copy files (dll) from internet, Win7 blocks it. The unblock option appears as in the following image when we take the file properties. What command can I use to unblock the file from a batch file?

Accepted Answer

Supposedly this should work:

```
echo.>myDownloadedFile.exe:Zone.Identifier
```

See a more detailed discussion here, Unblock a file with PowerShell?, which also describes other approaches using Powershell and the `streams` tool from SysInternals.
