1、使用c+對磁盤進行檢測，獲取磁盤相應的信息tern "c" _decpec(dll)int getlogicdiskinfo() int dtype; int si = 0; bool relt; unsign _int64 i64freebytestocaller; unsigned _int64 i64totalbytes; unsigned _int64 i64freebytes; float totalsize;/總空間 float usablesize;/可用空間 int dslength = getlogicaldrivesings(0,null);/通過該函數

2、獵取全部驅動器字符串信息長度 cout "長度為：" dslength endl; ofstream in;/向文件寫內容 in.open("d:diskinfo.txt",ios:tru);/ios:trunc表示在打開文件前將文件清空，因為是寫入操作，當文件不存在則創建 char* dstr = new chardslength; getlogicaldrivestrings(dslength,(lptstr)dstr); for(int i=0;i dslength/4;+i) char dir3 = dstrsi,':','
