Hi,



I have uploaded a report which runs and renders perfectly. But I am
unable to export it into any format. It fails with the following
error:


Server Error in '/Reports' Application.
--------------------------------------------------------------------------------

The file exists.

Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details: System.IO.IOException: The file exists.


Source Error:

An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of
the exception can be identified using the exception stack trace

Has any one faced this issue?

Would appreciate any help in resolving this. Let me know if you would
need any more information.

The application has been running from quite some time and this problem
started just recently.

Thanks,

Amit.
