Replace data source for multiple layer files that resides in folder
Important: There might be group layers so we have to check them while replacing the data source
Situation: you have to replace the datasource of all the layers in the folder C:\Trial\layers
Initial datasource: C:\trial\sample\*********
after running script: D:\GIS\trial\**********
The area represented by the '*' above shows they are same content
import arcpy import glob layers = glob.glob(r"C:\Trial\layers\*.lyr") for lyr in layers: l = arcpy.mapping.Layer(lyr) for layer_inside in arcpy.mapping.ListLayers(l): #checking whether it's a group layer or not if layer_inside.isGroupLayer == False: group = layer_inside.name print "old: "+str(layer_inside.dataSource) #This will replace C:\trial\sample to D:\GIS\trial. layer_inside.findAndReplaceWorkspacePath(r"C:\trial\sample","D:\GIS\trial") print "new: "+str(layer_inside.dataSource) #Saving the layer files with dataset name arcpy.SaveToLayerFile_management(l, r"C:\Trial\layers2\\"+str(l.datasetName)+".lyr")
I will be updating soon with more code snippets!!
