You can use the PowerShell function below along with Get-Content to see a hexdump of the file contents, i.e., Get-Content -Encoding Byte 'MyFile.bin' | Format-HexDump. It takes about 23 seconds to dump a 222 KB file and, if desired, the output can be redirected to a text file to make examining the dump easier.
