Summary

Resolution

While there is no out of the box activity that deletes a particular file. This is possible via a custom activity.  The following is an example of code for deleting only the service export directory where the jar files or temporary attachments reside before they are imported into the database. If you want to delete any particular file from this service directory, you will have to make sure to get the file handle for that specific file using the absolute filepath or the PRFile API.

String tempPath = tools.getProperty("pxProcess.pxServiceExportPath").getStringValue();

PRFile afile = new PRFile(tempPath);

String list[] = afile.list();

for (int i = 0; i < list.length; i++) {

  oLog.infoForced(i+"I:"+list[i]);

  afile = new PRFile(tempPath+list[i]);

  oLog.infoForced("delete Status"+afile.delete());

}

There is also an option from the SMA to delete the entire static content cache.
