Oh, crap…i think somebody can help with the indentation stuff. i’m not a web pro when it comes to page styling.
or u can try this:
at
while.mdb:
next line 1 tab, upto
while fdset:
nextline 2 tabs, upto
while fc:
nextline 3 tabs,till fc=fcs.next()
then one tab back at fdset=listfdset.next()
one more tab back at mdb=listmdb.next()

additional:

gp.workspace = mdb + “” + fdset starts with 3 tabs after
if not fdset == None:

both the lines:
gp.Delete_management(fc)
print fc + ” deleted from” + mdb
starts with 4 tabs

sorry for the confusion, but it works. all the tabs are from the first column, except the coming back ones.
Happy automating!!!

I’m having trouble with Martin’s amended script.

I am no programmer… but I have had success with the original script provided, however I also wanted to remove feature datasets from my geodatabase.

When I run Martin’s amended script (having changed my geodatabase workspace) the result is that my script appears to get stuck in the while loop, as the window shows my geodatabase workspace location repeating over and over and over again.

Any suggestions?

Thanks for the improved script, Martin! I didn’t notice this because I’ve only used it with geodatabases that weren’t organized into feature datasets.

I tried your very useful script, but had to correct it a little bit. It cleaned only the first Feature DataSet, so I added an additional while-loop:

##############################################################
## Delete Empty Feature Classes from Multiple Geodatabases
##
## This script loops through all geodatabases within a directory
## and removes empty featureclasses from each geodatabase.
##
## User must hardcode directory. Run this script in IDLE.

## Python Version 2.4
##############################################################

# Create the Geoprocessor object
import arcgisscripting, os, sys, string
gp = arcgisscripting.create()

# Load required toolboxes…
gp.AddToolbox(“C:\\Program Files\\ArcGIS\\ArcToolbox\\Toolboxes\\Conversion Tools.tbx”)

# Set workspace
gp.workspace = “C:\\tmp\\pgdb\\”

# list personal geodatabases in the current workspace
listmdb = gp.listworkspaces(“*”, “access”)
##listmdb = gp.listworkspaces(“*”, “FileGBD”)
mdb = listmdb.next()

# loop through the personal geodatabases
while mdb:
print mdb
gp.workspace = mdb
# list feature datasets in personal geodatabase
listfdset=gp.listdatasets()
fdset=listfdset.next()

# loop through feature dataset
while fdset:
#print “fdset: “, fdset

if not fdset == None:
gp.workspace = mdb + “\\” + fdset
# list feature classes in the personal geodatabase
fcs = gp.listfeatureclasses()
fcs.reset()
fc = fcs.next()

# loop through the featureclasses
while fc:
#print fc, gp.GetCount_management(fc)

# if the feature class table has no records, delete the featureclass
if gp.GetCount_management(fc) == 0:
gp.Delete_management(fc)
print fc + “deleted from ” + mdb
fc = fcs.next()

fdset=listfdset.next()

mdb = listmdb.next()
