请问如何判断两个多媒体文件是一样的呢？(50分)

请问如何判断两个多媒体文件是一样的文件的呢，比如说两个a.dat和b.dat，先谢了

你指的是什么一样啊。
是类型一样呢？还是文件名一样啊。
如果是类型一样的可以用
var
Rec:TsearchRec;

ExtractFileExt(path) 提取后缀名，

不好意思，刚才没说清楚，是比校文件里的内容（前提当然是文件的扩展名是一样的）。

Win2K:
Start->Run->cmd

C:/>fc /b a.dat b.dat

如果要编程的话,就用FileStream来做.

用MD5算法算出两个文件的MD5值，一样则文件一样。
现在市面上很多Windows N合一 光盘就是基于这个算法来优化文件的。

用 CRC32 效俭, CRC32 可以比较任何的文件,包括多媒体文件是否一样,被广泛用在防毒软件中

呵呵！
可以提供一个简单而直接的方法！
比较两个文件的大小嘛！
如果两个文件的大小一致（精确到字节），却内容不一致的话，可能性不大哦！

bluepoint8868,你这个方法不行，万一文件大小真的一样呢？

幕后黑手：
请问如何使用你写的那个CRC32，我主要比较的是流媒体文件。因为我想删除相同的文件，每个文件有50M左右吧，用Delphi编程实现比较。

gear1023：
请问用FileStream如何实现呢？

to:gear1023
Fc命令是用来比较来个文件的长度的，并不是比较文件内容；

要完整比较我想应该系用文件流吧！

你只要在你代码中添加
uses Crc32;

然后你可以这样取得文件的数字
ComputeFileCRC32(文件路径)

如果数字一样就时一样的文件，如果不一样内容就不同

Jaby,老兄你懂不懂什么叫算法？回去大学多读两年再回来混。
用文件流每个字节比较的话跑一个 100 GB 的不要等死人了。

幕后黑手:
我引用Crc32；后
procedure TForm1.Button1Click(Sender: TObject);
var filesize1, filesize2 : LongInt;
begin

filesize1:=ComputeFileCRC32('d:/1.mp3');
edit1.Text :=inttostr(filesize1);

filesize2:=ComputeFileCRC32('d:/2.mp3');
edit2.Text :=inttostr(filesize2);
end;


时出现'file access denied'的错误！是不是这样调用不行呢？

刀刀温柔,如果你在检查运行中文件的话就会出现这种情况

幕后黑手：
我比较*.txt、*.doc、*.exe, *.dat,运行正常可是当比较*.mp3时就会报那样的错！
leejames：
我用MD5算一个200M的文件花了1分钟时间！看来用MD5还是不太行

你的机器什么配置？ 我CIII 1.1G的机器 215MB的ASF文件才24秒。
事实上MD5的算法和CRC32复杂度相差不大，速度也不会差太多。
CRC32出现重复值的可能性远远大于MD5，我想这也是那些优化软件采
用MD5的主要原因。

我的比较差，C633,128M内存。我一般比较120M左右的*.mp2文件或50M*.dat。
服务器上有2万多个文件。
我是这样想的，先判断文件大小是否一样，若一样的再用MD5进一步比较，当MD5值相等则删除其中一个文件。
先把MD5的贴上来看看这个算法有没出问题，谢谢大家关注

直接取到内容中进行比较可能速度要好些吧

你的MD5算法实现是比较严格的按标准来写的了，不过有些小细节可以优化一下。
一些一行的函数像 F，G，H，I， ROT等全部分解到FF、GG、HH...中去。在大
文件中这些函数频繁的调用会消耗很多时间。
