Hello Everyone,

I was trying to save my plot as png images using Makie.jl in a for loop which constantly updates the plot.

Here is my code snippet which saves the plot:

![image](https://global.discourse-cdn.com/julialang/original/3X/b/e/be18cae418ecad810ed00cb37bc377b9d349a82a.png)

where file\_no is the iterable variable in the for loop and changes value.

This is the error I get:

```julia
SystemError: opening file "Frame:\\ 1.png": Invalid argument

var"#systemerror#69"(::Nothing, ::typeof(systemerror), ::String, ::Int32)@error.jl:174

```

  
I can't figure out the error, any help would be appreciated. Thanks.

I think a `:` in a filename is not allowed

Hi again @jules

Thanks for the quick response. Removing ‘:’ in the filename fixed the error.

In Windows; MacOs, Linux and more Unix like, does accept `:` as part of a filename. 🙂

(Not that I recomend using it. 😅 )
