I renamed part with solidwors explorer and this part using an assembly. I clicked "update parts where it was used use it option " but when I open assembly part file location disappear.
I'm not sure I totally follow what you mean here.......
What version of SolidWorks are you using?
Am I correct in saying that you renamed a part that was used in an assembly?
But from there I don't understand you. Have you lost the part file location or the assembly file location?
I think Abdullah is referring to the function to update all references / where used - but it's been a while since I used SW explorer so I don't remember the options.
I am using Solidworks 2017 Sp1.0.
