商业源码 隐藏的文件弄不出来了？
修改HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL右边CheckedValue的键值为1
下面是七种方法来隐藏文件或文件夹。 你可以反其道行之:
1“回收站”本是用来暂存已被删除的文件，但如果将我们的个人文件隐藏在“回收站”中，那就可能谁也不会去关注它了。首先，我们在“文件夹选项”中的“查看”选项卡中选择“显示所有文件”，然后进入系统所在分区的根目录，右击“Recycled”文件夹选择“属性”命令，在“属性”对话框中勾选“启用缩略图查看方式”复选框，点击“应用”按钮。这样，系统就会自动将“回收站”的“只读”复选框选中，然后去掉“只读”复选框前的钩，此时，“回收站”的图标将变成一个普通文件夹的形状。双击“Recycled”文件夹，将需要隐藏的个人资料拖进该文件夹窗口中，然后再次右击“Recycled”文件夹并选择“属性”命令，勾选“只读”复选框后，“回收站”图标就又恢复成原状。此后，如果有人双击“回收站”，他就根本看不到里面有任何文件。即便其他用户执行了文件删除操作，同时又执行了“清空回收站”的操作，原先被隐藏在这里的文件仍不会被删除。通过巧妙切换“Recycled”文件夹的属性，我们便可以用它来隐藏自己的秘密文件。
2、将个人文件夹变为“回收站” 我们还可以利用“偷梁换柱”的手法，即将我们的个人文件夹图标变为“回收站”图标。首先，在“Recycled”文件夹的属性窗口中去除掉“只读”属性，以便让它变为普通文件夹图标，进入“Recycled”文件夹并将其中的“desktopini”隐藏文件复制到需要隐藏的文件夹下，例如“d:\zhj”；右击“zhj”文件夹并选择“属性”命令，在弹出的对话框中勾选“只读”、“隐藏”复选框，再勾选“启用缩略图查看方式”复选框。现在我们就会发现，“zhj”文件夹已变成“回收站”图标了，但当他人打开该文件夹所看到的却是原来“Recycled”文件夹中的内容，而不会是“zhj”文件夹里的文件。当然，别忘了在“文件夹选项”的“查看”选项卡中选中“不显示隐藏文件”项。
3、始终不显示隐藏文件 在Windows98中，一般地，我们可以通过在个人文件的“属性”对话框中勾选“隐藏”复选框，然后在“文件夹选项”的“查看”选项卡中选择“不显示隐藏文件”单选按钮来达到隐藏秘密的目的，但稍具计算机知识的人只要选择“显示所有文件”单选按钮就能将它们全部显示出来，因此，如果用以上方法来隐藏个人文件的话，就必须对“显示所有文件”这个命令加以限制。方法是：在注册表编辑器中找到“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows<BR>\CurrentVersion\explorer\Advanced\Folder\Hidden\SHOWALL”分支，然后在右窗口中找到二进制子键“Checked value”，把其键值改为“0”。这样，即使在“查看”选项卡中选择了“显示所有文件”，但系统仍不会显示出隐藏着的个人文件。并且当他人重新进入“查看”选项卡，他就会发现，系统又自动选中了“不显示隐藏文件”这一项！ 更绝的是，利用注册表编辑器，我们可以将“查看”选项卡中的“隐藏文件”项下的三个单选按钮都隐藏掉。我们只需将上述“Hidden”下“NOHIDDEN”、“NOHIDORSYS”、“SHOWALL”三个分支中的“Text”字符串键(注：Windows XP中该键的键值不同)的健值清除掉。这样，退出注册表编辑器后再进入“查看”选项卡，你就会发现“隐藏文件和文件夹”下面空空如也(如图)。任何人想要查看我们的个人文件就都是两个字——没门，因为这个地方根本没法选择！
4、隐藏个人驱动器 由于笔者在单位中使用的计算机是公用的，因此，笔者就用PartitionMagic在硬盘中划出了一个50M的新驱动器(符号为G，然后将笔者的个人文件全部存放到这里，再将这个分区隐藏掉。这样，别人就不会知道这台计算机中还有一个50M的驱动器。方法是：进入上面方法三中的Explorer子键，在其下新建一个“NoDrivers”的二进制值，将其值改为“40000000”即可。
5 系统目录警告 操作：打开Windows文件夹，找到里面的两个文件：Folderhtt和Desktopini(如果找不到，通过“查看”菜单将文件夹选项设成显示全部文件。)，将其复制到需要隐藏的文件夹里，并将文件夹属性设为只读。用记事本打开文件夹里的Folderhtt，删除“显示文件”四个字。 “显示文件”不见了 评价：当你想打开这个文件夹时，会像Windows系统目录一样，出现一段警告语，而且，没有了“显示文件”四个字，让人无处下手(如图1)。但是，只要去掉只读属性，文件全都乖乖地呈现在你面前。
6 添加系统属性 操作：在方法三的基础上，添加系统属性。进入DOS环境，在命令行后面输入attrib +s + r(文件夹名)，这样就给文件夹添加了系统属性。由于系统属性呈灰色(未激活状)，一般人拿它没有办法。 “系统”属性未激活 评价：此法看似很绝，除非熟悉DOS的人进入那个黑色的世界去掉系统属性，否则，你无法窥探里面的秘密。其实不然，只要你换一种方法，丢开“我的文档”、“我的电脑”，改从资源管理器进入，什么“警告”，什么“系统属性”，都一览无余。
7 添加“隐藏”属性 操作：此方法很简单，只需要右键单击文件夹，再点击属性，在属性中勾选隐藏。然 后，点击菜单上的[查看]→[文件夹选项]→[查看]，在“隐藏文件”选项卡中选上“不显示隐藏文件”即可。 评价：只要设置显示全部文件，你就无处藏身。此法只有菜鸟为之，当然，也只能隐瞒菜鸟。
总评：如此看来，所谓隐藏文件夹，只要能够隐藏，就有方法显示(实际上恢复)。要想保证文件的安全，最好还是多方着手。首先给文件或文件夹取一个假名，让人以为只是一个并不重要的文件；同时，给文件加上密码；然后，采用多种隐藏方法同时隐藏文件夹。当然，多申请几个免费邮箱，将重要的文件藏到里面比上面的几种方法都好，而且可以作为移动公文包，到哪里都能打开使用，你说呢

例如：
"文件名1DOC"的扩展名"DOC"表示本文件是一个"Microsoft Word 文档"，
"文件名2XLS"的扩展名"XLS"表示本文件是一个"Microsoft Excel 工作表"，
"文件名3BMP"的扩展名"BMP"表示本文件是一个"BMP格式图像"，
"文件名4MP3"的扩展名"MP3"表示本文件是一个"MP3 格式声音"，

不行的!
因为在windows里只有指定的集中后缀名，如dll等才会
被windows识别为受保护的系统文件。
不过你可以试试把要保护的文件的后缀名先改成"dll"，等到用的时候在改过来就行了。
但是你可以试试一下七种方法来隐藏文件或文件夹。
1“回收站”本是用来暂存已被删除的文件，但如果将我们的个人文件隐藏在“回收站”中，那就可能谁也不会去关注它了。首先，我们在“文件夹选项”中的“查看”选项卡中选择“显示所有文件”，然后进入系统所在分区的根目录，右击“Recycled”文件夹选择“属性”命令，在“属性”对话框中勾选“启用缩略图查看方式”复选框，点击“应用”按钮。这样，系统就会自动将“回收站”的“只读”复选框选中，然后去掉“只读”复选框前的钩，此时，“回收站”的图标将变成一个普通文件夹的形状。双击“Recycled”文件夹，将需要隐藏的个人资料拖进该文件夹窗口中，然后再次右击“Recycled”文件夹并选择“属性”命令，勾选“只读”复选框后，“回收站”图标就又恢复成原状。此后，如果有人双击“回收站”，他就根本看不到里面有任何文件。即便其他用户执行了文件删除操作，同时又执行了“清空回收站”的操作，原先被隐藏在这里的文件仍不会被删除。通过巧妙切换“Recycled”文件夹的属性，我们便可以用它来隐藏自己的秘密文件。
2、将个人文件夹变为“回收站” 我们还可以利用“偷梁换柱”的手法，即将我们的个人文件夹图标变为“回收站”图标。首先，在“Recycled”文件夹的属性窗口中去除掉“只读”属性，以便让它变为普通文件夹图标，进入“Recycled”文件夹并将其中的“desktopini”隐藏文件复制到需要隐藏的文件夹下，例如“d:\zhj”；右击“zhj”文件夹并选择“属性”命令，在弹出的对话框中勾选“只读”、“隐藏”复选框，再勾选“启用缩略图查看方式”复选框。现在我们就会发现，“zhj”文件夹已变成“回收站”图标了，但当他人打开该文件夹所看到的却是原来“Recycled”文件夹中的内容，而不会是“zhj”文件夹里的文件。当然，别忘了在“文件夹选项”的“查看”选项卡中选中“不显示隐藏文件”项。
3、始终不显示隐藏文件 在Windows98中，一般地，我们可以通过在个人文件的“属性”对话框中勾选“隐藏”复选框，然后在“文件夹选项”的“查看”选项卡中选择“不显示隐藏文件”单选按钮来达到隐藏秘密的目的，但稍具计算机知识的人只要选择“显示所有文件”单选按钮就能将它们全部显示出来，因此，如果用以上方法来隐藏个人文件的话，就必须对“显示所有文件”这个命令加以限制。方法是：在注册表编辑器中找到“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows<BR>\CurrentVersion\explorer\Advanced\Folder\Hidden\SHOWALL”分支，然后在右窗口中找到二进制子键“Checked value”，把其键值改为“0”。这样，即使在“查看”选项卡中选择了“显示所有文件”，但系统仍不会显示出隐藏着的个人文件。并且当他人重新进入“查看”选项卡，他就会发现，系统又自动选中了“不显示隐藏文件”这一项！ 更绝的是，利用注册表编辑器，我们可以将“查看”选项卡中的“隐藏文件”项下的三个单选按钮都隐藏掉。我们只需将上述“Hidden”下“NOHIDDEN”、“NOHIDORSYS”、“SHOWALL”三个分支中的“Text”字符串键(注：Windows XP中该键的键值不同)的健值清除掉。这样，退出注册表编辑器后再进入“查看”选项卡，你就会发现“隐藏文件和文件夹”下面空空如也(如图)。任何人想要查看我们的个人文件就都是两个字——没门，因为这个地方根本没法选择！
4、隐藏个人驱动器 由于笔者在单位中使用的计算机是公用的，因此，笔者就用PartitionMagic在硬盘中划出了一个50M的新驱动器(符号为G，然后将笔者的个人文件全部存放到这里，再将这个分区隐藏掉。这样，别人就不会知道这台计算机中还有一个50M的驱动器。方法是：进入上面方法三中的Explorer子键，在其下新建一个“NoDrivers”的二进制值，将其值改为“40000000”即可。
5 系统目录警告 操作：打开Windows文件夹，找到里面的两个文件：Folderhtt和Desktopini(如果找不到，通过“查看”菜单将文件夹选项设成显示全部文件。)，将其复制到需要隐藏的文件夹里，并将文件夹属性设为只读。用记事本打开文件夹里的Folderhtt，删除“显示文件”四个字。 “显示文件”不见了 评价：当你想打开这个文件夹时，会像Windows系统目录一样，出现一段警告语，而且，没有了“显示文件”四个字，让人无处下手(如图1)。但是，只要去掉只读属性，文件全都乖乖地呈现在你面前。
6 添加系统属性 操作：在方法三的基础上，添加系统属性。进入DOS环境，在命令行后面输入attrib +s + r(文件夹名)，这样就给文件夹添加了系统属性。由于系统属性呈灰色(未激活状)，一般人拿它没有办法。 “系统”属性未激活 评价：此法看似很绝，除非熟悉DOS的人进入那个黑色的世界去掉系统属性，否则，你无法窥探里面的秘密。其实不然，只要你换一种方法，丢开“我的文档”、“我的电脑”，改从资源管理器进入，什么“警告”，什么“系统属性”，都一览无余。
7 添加“隐藏”属性 操作：此方法很简单，只需要右键单击文件夹，再点击属性，在属性中勾选隐藏。然 后，点击菜单上的[查看]→[文件夹选项]→[查看]，在“隐藏文件”选项卡中选上“不显示隐藏文件”即可。 评价：只要设置显示全部文件，你就无处藏身。此法只有菜鸟为之，当然，也只能隐瞒菜鸟。
总评：如此看来，所谓隐藏文件夹，只要能够隐藏，就有方法显示(实际上恢复)。要想保证文件的安全，最好还是多方着手。首先给文件或文件夹取一个假名，让人以为只是一个并不重要的文件；同时，给文件加上密码；然后，采用多种隐藏方法同时隐藏文件夹。当然，多申请几个免费邮箱，将重要的文件藏到里面比上面的几种方法都好，而且可以作为移动公文包，到哪里都能打开使用，你说呢
