equals

public static boolean equals(java.io.File a_oneFile,
                             byte[] a_md5HashSecond,
                             long a_sizeSecond)

equals

public static boolean equals(java.io.File a_oneFile,

Compares two files. May optionally do a comparison of MD5 hashes if speed does not matter.

Parameters:

a_oneFile -

a_otherFile -

a_hashComparison - if true, the MD5 hashes of the two files are compared if they seem to be equal after a quick check; false otherwise
