Parameters:

srcFile - - the validated source file, may not be null

destFile - - the validated destination file, may not be null

preserveFileDate - whether to preserve the file date

Throws:

IOException - if an error occurs

IOException - if the output file length is not the same as the input file length after the copy completes

IllegalArgumentException - "Negative size" if the file is truncated so that the size is less than the position
