c++ - Get files creation or modification time? -


i want creation or modification time of files , compare system time.

if (fileextensions[i] == restoken   &&  lmdcheck.getcheck() == true) {     testbox3.addstring(allfiles[i]);     cfilestatus status;     cfile cfile;      //cfile.open(allfiles[i],null,null);     cfile.open(allfiles[i], cfile::moderead | cfile::modewrite);      ctime t = ctime::getcurrenttime();     trace(t.format(l"%x\n"));      systemtime systemtime;     //::getsystemtime(&systemtime);     ::getlocaltime(&systemtime);     ctime systemt(systemtime);     trace(systemt.format(l"%x\n"));     ulonglong dwnewlength = 10000;     cfile.setlength(dwnewlength);      if (cfile.getstatus(status))     {         if (status.m_ctime < systemtime)         {             cfile.close();             cfile::remove(allfiles[i]);         }     } }

and delete file less system time. please help?

this compare file's filetime current systemtime

bool get_finddata(const tchar *filename, win32_find_data &data) {     if (!filename) return false;     handle h = findfirstfile(filename, &data);     if (h == invalid_handle_value)         return false;     findclose(h);     return true; }  void change_filetime(filetime &ft, int sec) {     ulonglong temp = (((ulonglong)ft.dwhighdatetime) << 32) + ft.dwlowdatetime;     temp += sec * __int64(10000000);//100-nanosecond intervals     ft.dwlowdatetime = (dword)(temp & 0xffffffff);     ft.dwhighdatetime = (dword)(temp >> 32); }  void checkfor_older_files(const tchar *filename) {     win32_find_data finddata;     if (!get_finddata(filename, finddata)) return;     //finddata.ftcreationtime;     //finddata.ftlastwritetime;     //finddata.ftlastaccesstime;      systemtime st;     getsystemtime(&st);      filetime comparetime;     systemtimetofiletime(&st, &comparetime);      //change comparetime, example, files older 30 minutes     change_filetime(comparetime, -30 * 60);      if (comparefiletime(&finddata.ftcreationtime, &comparetime) < 0)         outputdebugstring(l"older file\n");     else         outputdebugstring(l"not old\n"); }
