Deleting the files from exception folders

Dear All

We are on MDM 5.5 sp06 using auto import and syndication.

Whenever the files to be imported are having value exceptions logs are written in the parent Exception folder as well as the file is also placed in the ValueX subfolder within the exception folder which contains the virtual extended records.

What is the recommended way of deleting the log files in parent exception folder and the source files from the ValueX/Structure subfolders?

Can we set up some archiving process? Is there any standard methods available? Please share the methods used in similar situations.

thanks in advance-

Ravi
