PPT软件技巧系列:PPT的加密方法

在前不久的《善用版本功能》中,我提到过文档专业性的一个要点:不可编辑性。比如:不要把word文件发给客户,而应先转换成PDF格式。事实上,在我的工作中,往往会有大量使用PPT的场合,而很多客户也会表示希望通过邮件发送PPT文件给他们。这时,如果PPT转换成PDF格式发送过去,虽然也没有问题,但是对于PPT中的一些动画效果就丧失了。而不转换PDF格式的话,PPT就具备了可编辑性,包括PPT文档中的某些商业数据,图片都很容易被编辑和修改,这显然是不专业的做法。

更改后缀为PPS

如果你将PPT文件的后缀更改为PPS,那么任何人只要双击这个文件,就会进入播放模式,而不是编辑模式,这样的优点是显著的,对于某些没有电脑常识的人来说,就避免了他编辑这个PPT文件的可能。当然,这种方法也许只能对极少数人有作用。

为PPT增加修改密码

PPT的密码保护分为两个层级:

  • 打开保护
  • 修改保护

我们来看看如何增加修改密码。
首先,选择PPT“另存为”,这样在下面的窗口右上角,可以看到“工具”下拉列表。

在这个下拉列表中,选择安全选项。

 

这样,你就可以来到添加打开密码和修改密码的界面。

在修改权限密码中输入你定义的密码。(和其他输入密码的环节一样,这里也需要你输入两次以确认)

特别提示:如果你认为自定义的字母与数字组成的密码具有可破解性,那么,你可以选择用“中文”密码,做法如下:

在txt文档中输入“这是一个中文密码”8个汉字。拷贝这一串汉字,然后粘贴到密码栏中。当然,如果你在此打开此文档,也需要利用粘贴的方法来输入这串中文密码。至此,你已经设置了PPT修改密码,接下来你可以试试打开这个有修改密码的PPT文件。

打开加密的PPT

这时,你会遭遇这样的窗口:

你有两个选择,

1,输入密码,点击确定,这样进入PPT编辑模式。
2,直接点击只读,这样你不具备编辑的权限。

显然,对于很多客户来说,可能会直接点击确定,这样会提示“密码不正确”,而忽视“只读”选项。

避开修改密码输入提示

此时,我们还记得pps格式可以直接进入演示模式,因此我们仅仅简单的将此加密的PPT文件后缀更改为PPS,如此,任何双击此文件的人,将直接进入演示模式,而且在没有密码的情况下,无法修改此PPT文档的内容。

特别提示

如果这是你第一次试图在工作中提高你的PPT技能,那你就走在了升职加薪的正确轨道上。这本书比较适合工作中使用ppt的朋友们,让你在老板面前立刻显得与众不同。
