aescrypt的确是一个文件加密的软件，它可以运行在多个操作系统上，比如windows，linux什么的。同时它采用的是业界通用的AES加密算法。
举例，如果你在windows上用的话，之需要右键点击一下文件，然后选择AES加密/解密，同时输入密码就好了。挺简单的。
这个我不清楚。
文件夹加密软件，我使用的是文件夹加密超级大师。
文件夹加密超级大师支持所有windows系统，可以加密文件夹，加密文件，保护磁盘和数据粉碎，使用起来非常方便。
在需要加密的文件和文件夹上单击鼠标右键选择加密就可以了。
解密时只要双击加密的文件夹和文件，输入正确的密码就可以解密。
文件夹加密超级大师加密后的文件和文件夹可以防止删除、复制和移动。
相对于其他的文件夹加密软件和文件加密软件，功能和性能还有操作都更加的出色。
并且有微软、360和金山的安全认证，是一款绝对安全的文件夹加密软件。
您可以到百度上下载文件夹加密超级大师来给您的文件和文件夹加密，看看使用效果怎么样？
