Are you closing the created/opened file before trying to delete it?

YES iam closing the files(fclose). and more over, the files were created in previous sessions. not in the session where iam trying to delete them. and my files have the extension .cry does it matter? here are some case studies. 1.iam trying to delete the s1.cry(created by my application) like this filename="s1.cry"; DeleteFile(rootpath+"\\cryfiles\\"+filename); RESULT : no use. 2.now i rename it through windows like s1.cry1 and filename="s1.cry1"; DeleteFile(rootpath+"\\cryfiles\\"+filename); RESULT : successful. any ideas?

To be honest... I have not tried more than what I told you. Im in a new project and my time for VC++ is limited. I will take a look this weekend at home. But it actually won't be so easy. I can not simulate your problem, my scrolls are working ok.

I make it like follows:
void CMyView::OtherFunction ()
{
char FileName[MAX_PATH];
GetModuleFileName(NULL, FileName, MAX_PATH);
m_szOfflineName = FileName;
m_szOfflineName = m_szOfflineName.Left(m_szOfflineName.ReverseFind('\\'));
m_szOfflineName += "\\OfflinePCode.pc";
}
.
.
void CMyView::OnDestroy()
{ CFormView::OnDestroy();CFile f; //The offline PCode is not needed anymore if (f.Open (m\_szOfflineName, CFile::modeRead)) { f.Close (); f.Remove (m\_szOfflineName); }}
But I am in MFC, I dont know if u can use the CFile
