110.文件搜索,系统大小获取,以及病毒行为

拷贝文件

 1 //拷贝文件
 2 void copy()
 3 {
 4     //自身路径
 5     char selfpath[256] = { 0 };
 6     //Windows路径
 7     char windowpath[256] = { 0 };
 8     //系统路径
 9     char systempath[256] = { 0 };
10 
11     //获取自身路径
12     GetModuleFileNameA(NULL, selfpath, 256);
13     //获取Windows路径
14     GetWindowsDirectoryA(windowpath, 256);
15     //获取系统路径
16     GetSystemDirectoryA(systempath, 256);
17     strcat(windowpath, "\test.exe");
18     strcat(systempath, "\test.exe");
19     //输出目录
20     printf("%s
", selfpath);
21     printf("%s
", windowpath);
22     printf("%s
", systempath);
23     //拷贝函数
24     CopyFileA(selfpath, windowpath, FALSE);
25 }

遍历所有磁盘信息

 1 //遍历所有磁盘信息
 2 void find_all()
 3 {
 4     char szbuf[100] = { 0 };
 5     //载入磁盘信息
 6     GetLogicalDriveStrings(100, szbuf);
 7     char *p = szbuf;
 8     while (*p != '')
 9     {
10         printf("%s
", p);
11         getspace(p);
12         p += strlen(p) + 1;
13     }
14 }

获取磁盘大小

 1 //获取磁盘大小
 2 int getspace(char *pstr)
 3 {
 4     //剩余空间 可用空间  总大小
 5     ULARGE_INTEGER dwl, dwfree, dwtol;
 6     char szsize[128] = { 0 };
 7     double size = 0;
 8     GetDiskFreeSpaceEx(pstr, &dwl, &dwtol, &dwfree);
 9     size = dwtol.QuadPart / 1024.0 / 1024 / 1204;//GB
10     printf("总大小:%f GB
", size);
11     size = dwl.QuadPart / 1024.0 / 1024 / 1204;//GB
12     printf("剩余空间:%f GB
", size);
13     size = dwfree.QuadPart / 1024.0 / 1024 / 1204;//GB
14     printf("可用空间:%f GB
", size);
15 }
