File on FTP Server is locked after FtpGetFile

Operations:

1 FTP Server running on IIS offers ftp service.
2 I write a VB ftp program to download a file.
3 To download the file I run the API:

bRet = FtpGetFile(hConnection, szFileRemote, szFileLocal & "/" & szFileRemote, False, _
INTERNET_FLAG_RELOAD, dwType, 0)

4 File download successful.

Problem: File is locked on the server. It cannot be deleted or updated. Restarting IIS doesn't help. Only way to unlock file is to restart the server.


Any clues as to why this happens?

Thanks,

To work around this problem, use a different editor or use the Registry Editor to disable caching of file handles.
