Save layer file to data source path

[FabioTuccini]

Hello,

I'm trying to write a code to save the layer file (.lyrx) for each layer present in my project in the same folder of the data source.

At the moment I can only one by one, with the following code:

import arcpy
arcpy.mp.ArcGISProject('CURRENT')
arcpy.management.SaveToLayerFile('layer','output_path', 'RELATIVE')

But I wold like to create a iteration with all  layers in my project. It's important that each .lyrx will be saved in the data source path.

Someone can help please

You are almost there, just put your code in the layer iteration:

m = aprx.listMaps("map name")[0]
for lyr in m.listLayers():
    if !lyr.isGroupLayer:
        arcpy.management.SaveToLayerFile(lyr,'output_path', 'RELATIVE')

 Something like above, but I haven't tested code myself.

Thanks a lot, yes we are almost there but still missing somenthing.

I have modified the code as follow:

import arcpy
aprx = arcpy.mp.ArcGISProject('CURRENT')
m = aprx.listMaps('Map') [0]
for lyr in m.listLayers():
if lyr.isGroupLayer:
arcpy.management.SaveToLayerFile(lyr,'output_path', 'RELATIVE')

The  layer iteration is working but is replacing the outputfile with the same name.

I would like to get the output file name with the layer name and in the same folder of the source data. Is it possible?

OK, I'm very close!

I've modified the code as follow:

import arcpy
aprx = arcpy.mp.ArcGISProject('CURRENT')
m = aprx.listMaps('Map') [0]
for lyr in m.listLayers():
if lyr.isFeatureLayer:
arcpy.management.SaveToLayerFile(lyr,lyr.dataSource + lyr.name, 'RELATIVE')

But I get the following error message:

Finally i found the solution. Maybe to someone can help, here the final code:

import arcpy
import os
aprx = arcpy.mp.ArcGISProject('CURRENT')
m = aprx.listMaps('Map') [0]
arcpy.env.overwriteOutput = True
for lyr in m.listLayers():
if lyr.isFeatureLayer:
arcpy.management.SaveToLayerFile(lyr,os.path.dirname(lyr.dataSource)+"\\"+lyr.name, 'RELATIVE')
