可以自己定义一个格式文件，把文件通过某种加密以后打进格式文件里，并且把文件夹和文件路径作为结构信息同时打进格式文件，解密时再按相反顺序解开.

枚举所有的文件以及子文件夹中的所有文件，按自己定义的结构，将所有的文件联接到一个文件中，再对这个文件加密和压缩，
解密时按自己的结构，再分开来，
以上是最简单的方式。

就是使用一般的压缩软件的库,如zip的在压缩的时候就要求你输入密码作为打开该压缩文件依据,你在网上找找应当很多的

那API
过于简单吧。怎么能加密文件夹呢？

windows提供了加密的API
EncryptFile
The EncryptFile function encrypts a file or directory.
All data streams in a file are encrypted. All new files
created in an encrypted directory are encrypted.
BOOL EncryptFile(
LPCTSTR lpFileName // file name
);
Parameters
lpFileName
[in] Pointer to a null-terminated string that specifies
the name of the file or directory to encrypt.
The caller must have FILE_READ_DATA, FILE_WRITE_DATA,
FILE_READ_ATTRIBUTES, FILE_WRITE_ATTRIBUTES, and
SYNCHRONIZE access to the file.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get
extended error information, call GetLastError.
Remarks
The EncryptFile function requires exclusive access to
the file being encrypted, and will fail if another
process is using the file.
If the file is already encrypted, EncryptFile simply
returns a nonzero value, which indicates success. If
the file is compressed, EncryptFile will decompress
the file before encrypting it.
To decrypt an encrypted file, use the DecryptFile
function.
Requirements
Windows NT/2000: Requires Windows 2000 or later.
Windows 95/98: Unsupported.
Header: Declared in Winbase.h; include Windows.h.
Library: Use Kernel32.lib.
Unicode: Implemented as Unicode and ANSI versions on
Windows 2000.

或者你用压缩什么的，同时加密
