CVI 文件的相关操作

1.新建一个空白的文件

	char filePath[256];
	int fileHandle;

	if (FileExists( FILE_PATH,0)< 1)//检测文件夹是否存在,FILE_PATH为文件夹路径
	{
		CreateDirectory(FILE_PATH, NULL);//创建文件夹
	}
	sprintf (filePath, "%s\\%s.txt", FILE_PATH, fileName);  
	if (1 == FileExists (filePath, NULL))//如果文件存在
	{
		DeleteFile (filePath);//删除文件
	}
	fileHandle = OpenFile (filePath, VAL_READ_WRITE, VAL_OPEN_AS_IS, VAL_ASCII);//新建文件夹
	CloseFile (fileHandle);//关闭文件

2.重命名

char existingFilePath[64], newFilePath[64]; 

sprintf (existingFilePath, "%s\\%s.txt",  TPF_FILE_PATH, existingFileName);
sprintf (newFilePath, "%s\\%s.txt", TPF_FILE_PATH, newFileName);   
RenameFile (existingFilePath, newFilePath);

3.删除文件

char filePath[64];  

sprintf (filePath, "%s\\%s.txt", TPF_FILE_PATH,  name); 
DeleteFile (filePath); 

4.另存为文件

char sourceFilePath[64], targetFilePath[64];  

sprintf (sourceFilePath, "%s\\%s.txt", TPF_FILE_PATH, sourceFileName);
sprintf (targetFilePath, "%s\\%s.txt", TPF_FILE_PATH, targetFileName);
CopyFile (sourceFilePath, targetFilePath);
