I would like to change the file description with a python code on ArcMap (10.6). I could not find a way to do it or resource explaining it.
Do you have any idea?

Take a look at Layer - ArcGIS Desktop Help.
lyr = arcpy.mapping.ListLayers(mxd)[0]
lyr.description = "This is the description of this layer"

Thank you @Midavalo . I figured how to work this out but also realized that is not what I wanted. I do not have a map file (.mxd) or layer file (.lyr). I have bunch of raster files that I want to put the same description for each of them. I guess it involves with metadata manipulation. As far as I understand this method creates a layer or read layers from a map document. For example, if I send my original file (.img) to somebody without the layer file, he will not see the description I created, right?– AmadeusCommented Aug 9, 2018 at 20:49

@OguzSariyildiz Correct. Also if you send the original
.imgfile to somebody without the metadata file, he will not see the description.– Midavalo ♦Commented Aug 10, 2018 at 1:36 -
I cant get this to work from within ArcMap. I need to set the description of all layers in a document. I've tried saving the mxd, save a copy, export the layer to lyr. The description is not set. Do you know why?– BeraCommented Sep 5, 2022 at 12:41

1@BERA I wonder if there's been a change in the syntax since 2018? I'll take a look next time I'm at my PC and see what happens for me.– Midavalo ♦Commented Sep 7, 2022 at 0:10
