Not sure if this applies in your case, but according to MSDN:
In rare cases, file attribute information on NTFS file systems may not be current at the time you call this function. To obtain the current NTFS file attributes, call GetFileInformationByHandle.Karl - WK5M PP-ASEL-IA (N43CS) PGP Key: 0xDB02E193 PGP Key Fingerprint: 8F06 5A2E 2735 892B 821C 871A 0411 94EA DB02 E193

the if statement. the date of the file i wish to delete is 2/5/2005 which gives tmCreate {m_time=1157539835 } and i want to delete files which are older than 11 days olds which gives me a time of {m_time=1156699696 } so the if statement reads if(tmCreate < (CTime::GetCurrentTime() - CTimeSpan(nDays,0,0,0))) i.e {m_time=1157539835 } < {m_time=1156699696 } but how can i file older have a m_time value higher than the time of 11 days ago perhaps thats where its going wrong any ideas ?

No, it doesn't. It gives you: 1107590400
