// Notes for possible future content checks:
// - Protected files (that haven't been renamed) will contain a couple of strings at the end:
// + SafeLock.dat
// + Proszê w³o¿yæ p³ytê CD do CDROM-u
// + Proszê w³o¿yæ oryginaln¹ p³ytê CD do CDROM-u
// - Also at the end is an ASCII number possibly indicating version:
// + 0.99.15 uses "3144288522"
// + 0.99.22 uses "1614884465"
// + 1.0.4 uses "3574069264"
// - All of the above is at the very end of the file
// - All auxiliary files (like .001, .128, and .dat) seem to be encrypted or padding data
