DeleteFile returns error when directory has >32,000 files in it.

[jfish]

I have a directory that dump text results files into for history.  With a few test systems running it gets a lot of small files in it.  I have an application that uses DeleteFile() to attempt to delete a file if already exists before writing a new one (title has UUT serial number in it).  I get an error (not ACCESS_DENIED or NO_FILE) when the number of files in the directory gets near 32,700.  Is there a timeout value or other limit to this function?  Is there another function I can use (SDK)?  I'm using CVI 6.1.  Thanks.

Hi,

Maybe you could try using the Windows SDK function which has the same name as the CVI function :

BOOL DeleteFile(LPCTSTR lpFileName);

Because it has the same name as  the CVI function you should use :

#include <windows.h>
#undef DeleteFile

To get more informations look at this link : http://digital.ni.com/public.nsf/allkb/69C82671913CAA4986256E9400676E17?OpenDocument

Kind regards,

This issue was resolved in CVI 8.0 - in case you are looking to upgrade.
