Can you please post the exact code you’re trying to run which results in an error? I feel like you’re missing to put the path inside quotes to make it a string, but I don’t really know what you’re doing.

You need to pass the filepath as a string:

```julia
julia> include(myfile.jl)
ERROR: UndefVarError: `myfile` not defined
Stacktrace:
 [1] top-level scope
   @ REPL[197]:1

julia> include("myfile.jl")
ERROR: SystemError: opening file "...\\myfile.jl": No such file or directory

```
