上面介绍摘自Series 60 2.1 help。

主要使用方式就是用户给定一个path，也就是第一个参数const TDesC& aName，通过调用，该文件夹中的内容就会返回到第四个参数CDir*& anEntryList中，接下来这个list中存储的内容就是该文件夹下的文件信息，至于中间两个参数可以设置一些屏蔽信息，使得用户可以取出自己需要的文件信息。

查找相应文件：

-------------------------------------

TFindFile file_finder(aSession); // 1

CDir* file_list; // 2

TInt err = file_finder.FindWildByDir(aWildName,aScanDir, file_list); // 3

while (err==KErrNone)

{

TInt i;

for (i=0; iCount(); i++) // 4

{

TParse fullentry;

fullentry.Set((*file_list)[i].iName,& file_finder.File(),NULL); // 5,6,7

// Do something with the full Symbian OS filename

DoOneFile(aSession, fullentry.FullName()); // 8

}

delete file_list; // 9

err=file_finder.FindWild(file_list); // 10
