Delete (Data Management)
Summary
Permanently deletes data from disk. All types of geographic data supported by ArcGIS, as well as toolboxes and workspaces (folders, geodatabases), can be deleted. If the specified item is a workspace, all contained items are also deleted.
Usage
-
Data currently in use in another ArcGIS application cannot be deleted—the tool fails with ERROR 000464.
-
Deleting a shapefile also deletes ancillary files such as the metadata, projection, and index files.
-
Deleting a folder moves the folder to the system Recycle Bin, where it can be restored or permanently deleted.
-
Deleting a geometric network demotes all the feature classes in the network to simple feature types; Edge feature classes become line feature classes; and junction feature classes become point feature classes. Deleting the network also deletes all the related network tables and the orphan junction feature class from the geodatabase.
-
Deleting a database connection file does not delete the ArcSDE database. A database connection file is simply a shortcut to the database.
-
Deleting a relationship class deletes the row corresponding to that relationship from the relationship table.

Code Sample
The following Python Window script demonstrates how to use the Delete function in immediate mode.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.Copy_management(("majorrds.shp"), "majorrdsCopy.shp")
arcpy.Delete_management("majorrdsCopy.shp")
The following Python script demonstrates how to use the Delete function in a stand-alone script.
# Name: Delete_Example2.py
# Description: Delete majorrdsCopy.shp
# Import system modules
import arcpy
from arcpy import env
# Set workspace
ENV.workspace = "C:/data"
# Set local variables
in_data0 = "majorrds.shp"
out_data = "majorrdscopy.shp"
data_type = ""
# Execute Copy
arcpy.Copy_management(in_data, out_data, data_type)
# Execute Delete
arcpy.Delete_management(out_data, data_type)
