It's rather a messy business in Windows, as usual. You need the FindFirstFile and FindNextFile calls.

HANDLE FindFirstFile(
  LPCTSTR lpFileName,     // name of file for search
  LPWIN32_FIND_DATA lpFindFileData  // data returned
);

is the signature for the first one. The lpFindFileData returns:

typedef struct _WIN32_FIND_DATA {
    DWORD dwFileAttributes;
    FILETIME ftCreationTime;
    FILETIME ftLastAccessTime;
    FILETIME ftLastWriteTime;
    DWORD    nFileSizeHigh;
    DWORD    nFileSizeLow;
    DWORD    dwReserved0;
    DWORD    dwReserved1;
    TCHAR    cFileName[ MAX_PATH ];
    TCHAR    cAlternateFileName[ 14 ];
} WIN32_FIND_DATA;

where lpFindFileData points. FILETIME is another windows structure that can be converted to something sensible with the FileTimeToSystemTime call.

To find subsequent calls use:

BOOL FindNextFile(
  HANDLE hFindFile,                // search handle
  LPWIN32_FIND_DATA lpFindFileData // pointer to data on found file
);

When you are done remember to call FindClose.

It is actually quite easy, I wouldn't call that messy. See the artile at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/listing_the_files_in_a_directory.asp ("Listing the Files in a Directory"), which comes with full source code.

Well the way it is done is very similiar in Linux and Windows. I can not see how you can make it much easier but with some extra stuff for globbing. The orignal question is still not fully answered. he wants to delete files older then a certain   time. And now it's getting hairy which time to use?
Access time?
Creaton time?
Modification time?

We simply do not know.
