[File System Task] Error: An error occurred with the following error message: "Access to the path is denied.".

Hi All i have an SSIS package . The package has Foreach loop container and in that i have a File System Task and when i'm executing the package i'm getting the following error and warning.

Error:[File System Task] Error: An error occurred with the following error message: "Access to the path is denied."

Warning: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED.  The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

In the PROPERTIES i changed the MAXIMUM NUMBER of errors to 100 instead of 1 and i'm still getting the same error.

Please need some advice.

Thanks
