Problem: Files left behind on disk when performing certain Spatial Analyst functions

Description

Some temporary files are not being removed after some Spatial Analyst functions complete processing.

Cause

This is a known issue with ArcGIS 8.1.

The following files will not be removed:

· The INFO file generated by the Zonal Statistics function.
· The scratch table generated by the Histogram tool.
· Temporary shapefiles that get created when performing certain tasks, such as during projection, format conversion, or selection.

Solution or Workaround

A regular cleanup of your working directory will alleviate this problem. Always remove ESRI grids with ArcCatalog or ArcInfo Workstation in order to remove the associated INFO files.
