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;}
