遍历磁盘容量：

#include <stdio.h>#include <Windows.h>void GetDrivesType(const char* lpRootPathName){ UINT uDriverType = GetDriveType(lpRootPathName); switch (uDriverType) { case DRIVE_UNKNOWN:puts("未知磁盘"); break; case DRIVE_NO_ROOT_DIR: puts("路径无效"); break; case DRIVE_REMOVABLE: puts("可移动磁盘"); break; case DRIVE_FIXED: puts("固定磁盘"); break; case DRIVE_REMOTE: puts("网络磁盘"); break; case DRIVE_CDROM: puts("光驱"); break; case DRIVE_RAMDISK: puts("内存映射盘"); break; default: break; }}void GetDrivesFreeSpace(const char* lpRootPathName){ unsigned long long available, total, free; if (GetDiskFreeSpaceEx(lpRootPathName, (ULARGE_INTEGER*)&available, (ULARGE_INTEGER*)&total, (ULARGE_INTEGER*)&free)) { printf("磁盘: %s | 总计: %lld MB 已用: %lld MB 剩余: %lld MB \n", lpRootPathName, total >> 20, available >> 20, free >> 20); }}int main(int argc,char *argv[]){ DWORD dwSize = MAX_PATH; char szLogicalDrives[MAX_PATH] = {0}; // 获取逻辑驱动器号字符串 DWORD dwResult = GetLogicalDriveStringsA(dwSize, szLogicalDrives); if (dwResult > 0 && dwResult <= MAX_PATH) { char* szSingleDrive = szLogicalDrives; // 从缓冲区起始地址开始 while (*szSingleDrive) { //printf("Drive: %s\n", szSingleDrive); // 输出单个驱动器的驱动器号 // GetDrivesType(szSingleDrive); GetDrivesFreeSpace(szSingleDrive); szSingleDrive += strlen(szSingleDrive) + 1; // 获取下一个驱动器地址 } } system("pause"); return 0;}

遍历文件特定路径:

循环遍历文件路径,并将文件后缀为.exe的路径筛选出来.

#include <stdio.h>#include <windows.h>#include <tlhelp32.h>void SearchFile(char *pszDirectory){ // 搜索指定类型文件 char *pszFileName = NULL; char *pTempSrc = NULL; WIN32_FIND_DATA FileData = { 0 }; // 申请动态内存 pszFileName = new char[2048]; pTempSrc = new char[2048]; // 构造搜索文件类型字符串 *.* 表示搜索所有文件类型 wsprintf(pszFileName, "%s\\*.*", pszDirectory); HANDLE hFile = ::FindFirstFile(pszFileName, &FileData); if (INVALID_HANDLE_VALUE != hFile) { do { // 过滤掉当前目录"." 和上一层目录".." if ('.' == FileData.cFileName[0]) continue; // 拼接文件路径 wsprintf(pTempSrc, "%s\\%s", pszDirectory, FileData.cFileName); // 判断是否是目录还是文件 if (FileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) SearchFile(pTempSrc); // 如果是目录则继续递归 else { char drive[_MAX_DRIVE], dir[_MAX_DIR], fname[_MAX_FNAME], ext[_MAX_EXT]; _splitpath(pTempSrc, drive, dir, fname, ext); // 如果是文件并且后缀为.exe则输出具体路径 if (strcmp(ext, ".exe") == 0) printf("%s \n", pTempSrc); } } while (::FindNextFile(hFile, &FileData)); } FindClose(hFile); delete[]pTempSrc; delete[]pszFileName;}int main(int argc, char * argv[]){ SearchFile("c:\\MinGW7"); system("pause"); return 0;}

监控文件目录变化：

#include <stdio.h>#include <windows.h>#include <tlhelp32.h>UINT MonitorFileThreadProc(LPVOID lpVoid){ char *pszDirectory = (char *)lpVoid; // 打开目录, 获取文件句柄 HANDLE hDirectory = CreateFile(pszDirectory, FILE_LIST_DIRECTORY, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL); if (INVALID_HANDLE_VALUE == hDirectory) return 1; char szFileName[MAX_PATH] = { 0 }; BOOL bRet = FALSE; DWORD dwRet = 0; DWORD dwBufferSize = 2048; // 申请一个足够大的缓冲区 BYTE *pBuf = new BYTE[dwBufferSize]; if (NULL == pBuf) return 2; FILE_NOTIFY_INFORMATION *pFileNotifyInfo = (FILE_NOTIFY_INFORMATION *)pBuf; // 开始循环设置监控 do { RtlZeroMemory(pFileNotifyInfo, dwBufferSize); // 设置监控目录 bRet = ReadDirectoryChangesW(hDirectory, pFileNotifyInfo, dwBufferSize, TRUE, FILE_NOTIFY_CHANGE_FILE_NAME | // 修改文件名 FILE_NOTIFY_CHANGE_ATTRIBUTES | // 修改文件属性 FILE_NOTIFY_CHANGE_LAST_WRITE, // 最后一次写入 &dwRet, NULL, NULL); if (FALSE == bRet) break; // 将宽字符转换成窄字符,宽字节字符串转多字节字符串 WideCharToMultiByte(CP_ACP, 0, (wchar_t *)(&pFileNotifyInfo->FileName), (pFileNotifyInfo->FileNameLength / 2),szFileName,MAX_PATH,NULL,NULL); // 将路径与文件连接成完整文件路径 char FullFilePath[1024] = { 0 }; strncpy(FullFilePath, pszDirectory, strlen(pszDirectory)); strcat(FullFilePath, szFileName); // 判断操作类型并显示 switch (pFileNotifyInfo->Action) { case FILE_ACTION_ADDED: printf("文件被 [创建]: %s \n", FullFilePath); break; case FILE_ACTION_REMOVED: printf("文件被 [删除]: %s \n", FullFilePath); break; case FILE_ACTION_MODIFIED: printf("文件被 [修改]: %s \n", FullFilePath); break; case FILE_ACTION_RENAMED_OLD_NAME: printf("文件被 [重命名]: %s \n", FullFilePath); break; } } while (bRet); CloseHandle(hDirectory); delete[] pBuf; pBuf = NULL; return 0;}int main(int argc, char * argv[]){ char *pszDirectory = "C:\\"; // 创建线程开始监控 CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)MonitorFileThreadProc, pszDirectory, 0, NULL); while (1) { Sleep(10000); } system("pause"); return 0;}

监控目录文件变化:

可以将其改为一个简单的文件防篡改程序,也可以用来监控病毒的行为.

#include <stdio.h>#include <Windows.h>#include <tlhelp32.h>DWORD WINAPI MonitorFileThreadProc(LPVOID lParam){ char *pszDirectory = (char *)lParam; BOOL bRet = FALSE; BYTE Buffer[1024] = { 0 }; FILE_NOTIFY_INFORMATION *pBuffer = (FILE_NOTIFY_INFORMATION *)Buffer; DWORD dwByteReturn = 0; HANDLE hFile = CreateFile(pszDirectory, FILE_LIST_DIRECTORY, FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL); if (INVALID_HANDLE_VALUE == hFile) return 1; while (TRUE) { ZeroMemory(Buffer, sizeof(Buffer)); // 设置监控目录回调函数 bRet = ReadDirectoryChangesW(hFile,&Buffer,sizeof(Buffer),TRUE, FILE_NOTIFY_CHANGE_FILE_NAME | // 修改文件名 FILE_NOTIFY_CHANGE_ATTRIBUTES | // 修改文件属性 FILE_NOTIFY_CHANGE_LAST_WRITE, // 最后一次写入 &dwByteReturn, NULL, NULL); if (TRUE == bRet) { char szFileName[MAX_PATH] = { 0 }; // 将宽字符转换成窄字符,宽字节字符串转多字节字符串 WideCharToMultiByte(CP_ACP,0,pBuffer->FileName,(pBuffer->FileNameLength / 2), szFileName,MAX_PATH,NULL,NULL); // 将路径与文件连接成完整文件路径 char FullFilePath[1024] = { 0 }; strncpy(FullFilePath, pszDirectory, strlen(pszDirectory)); strcat(FullFilePath, szFileName); switch (pBuffer->Action) { case FILE_ACTION_ADDED: { printf("添加: %s \n", FullFilePath); break; } case FILE_ACTION_REMOVED: { printf("删除: %s \n", FullFilePath); break; } case FILE_ACTION_MODIFIED: { printf("修改: %s \n", FullFilePath); break; } case FILE_ACTION_RENAMED_OLD_NAME: { printf("重命名: %s", szFileName); if (0 != pBuffer->NextEntryOffset) { FILE_NOTIFY_INFORMATION *tmpBuffer = (FILE_NOTIFY_INFORMATION *) ((DWORD)pBuffer + pBuffer->NextEntryOffset); switch (tmpBuffer->Action) { case FILE_ACTION_RENAMED_NEW_NAME: { ZeroMemory(szFileName, MAX_PATH); WideCharToMultiByte(CP_ACP,0,tmpBuffer->FileName, (tmpBuffer->FileNameLength / 2), szFileName,MAX_PATH,NULL,NULL); printf(" -> %s \n", szFileName); break; } } } break; } case FILE_ACTION_RENAMED_NEW_NAME: { printf("重命名(new): %s \n", FullFilePath); break; } } } } CloseHandle(hFile); return 0;}int main(int argc, char * argv[]){ char *pszDirectory = "C:\\"; HANDLE hThread = CreateThread(NULL, 0, MonitorFileThreadProc, pszDirectory, 0, NULL); WaitForSingleObject(hThread, INFINITE); CloseHandle(hThread); return 0;}
