Hello everyone,

does anyone know how I can assign a file name with a variable in Node-Red version **0.19.4.**  
I want to write a file with a dynamic file name that contains the date.  
The variable works, I can read it with debug and see it among the variables. For example: g\_filename: xyz\_2025-04-09.txt  
If I enter the variable in the file node, the file is created with the variable name 'g\_filename' and not with the generated variable 'xyz\_2025-04-09.txt'.  
In the newer versions this works without problems. Does anyone know the trick in the old version 0.19.4?  
Oh yes .... an update is not an option 😉 true to the motto: never touch a running system!!!

Thanks already  
Roland

what does the nodes built in help say?

> ### Inputs
> 
> filename `string`  
> if not set in the node configuration, this property sets the filename to read.

i.e. leave it blank, ensure your file name is set in `msg.filename`

Yeah, if it works, dont change it. 👊

the system has no external access,  
I use it to control my heating and a few other things.

But you can never be sure! 🙄 🙈
