Hi richrichrich,

See the help for FILETOSTR(), STRTOFILE(), STRTRAN() and CHRTRAN().

You can also use FSEEK() and FWRITE()... once you FSEEK to a location in the middle of the file, FWRITE writes over whatever is there. I believe there are flags that must be set to avoid truncating the file at the end of the FWRITE output.

Depending on the size of the file, this may be much faster than FILETOSTR...etc... and if the file might ever grow bigger than 16MB, you cannot use FileToStr on files that big.
