Where I’m wrong?
(I’m following on YT Julia for nervous beginners) but now I’ returning in my steps because I met same problem in I/O text files where julia answer me: “no such file or directory” after order fh = open(“fname”)
after writing pwd() Julia write the same directory

`cd` stands for “change directory”, but you’re passing as argument a path to a file (.jl), not to a directory (cartella).
Restart Julia and try the following:
```julia
julia> pwd()
"C:\\Users\\Amministratore"
julia> cd(".\\Julia")
julia> pwd()
"C:\\Users\\Amministratore\\Julia"
julia> io = open("myfile.jl", "w");
julia> write(io, "Hello world!");
julia> close(io);
julia> io = open("myfile.jl", "r");
julia> read(io, String)
"Hello world!"
```
You can also open the file in a text editor and see for yourself that “Hello world!” was written.

Hey, thank you for your time that are you helping me, but seems that’s not working.
i read from others forums that should be a Julia bug, but the first time that i did work well.
I don’t know what to do.

you don’t `cd` into a FILE, you only `cd` into a directory (folder). `myfile.jl` is a file, you can’t `cd` into it

As @jling mentioned you can’t `cd` into a file. To get the parent folder from a file path you can do the following:
```julia
filepath = raw"C:\Users\Amministratore\Julia\myfile.jl"
parent_dir = dirname(filepath)
cd(parent_dir)
```
You can also check if the path is valid by using `isfile`,`ispath` or `isdir`
```julia
ispath(raw"C:\Users\Amministratore\Julia\myfile.jl")
isfile(raw"C:\Users\Amministratore\Julia\myfile.jl")
isdir(raw"C:\Users\Amministratore\Julia\myfile.jl")
```

thanks, give me “false” 🤷♂️
ispath–\> false
isfile–\>false
isdir–\>false LOL
even
`include("myfile.jl")` give me no such file or directory

`Users` not `User`
you can use `` complete the path as you’re typing it

What do you get when executing this?
```julia
c = raw"C:\Users\Amministratore\Julia\myfile.jl"
ispath.(accumulate(joinpath,splitpath(c)))
```

manipulated? (julia libraries?)
because the first time was ok…

Ok, so you don’t have a file called myfile.jl in C:\Users\Amministratore\Julia

so this should give you all the files in the Julia folder
```julia
c = raw"C:\Users\Amministratore\Julia\myfile.jl"
cd(dirname(c))
readdir()
```

exactly give me correct all them
`3-element Vector {String}: myfile.jl.txt new1.jl newfile.jl.jl`
already done all things with others 2 .jl

So you created a new file in windows while the file explorer was hiding the filename extensions.
The file is called `myfile.jl.txt` instead of` myfile.jl`

already done with others 2 same things that you suggested, doesn’t change nothing
`ispath(raw"C:\Users\Amministratore\Julia\newfile.jl") false`
isfile and others… i tried all

To read the content of the file you can run this
```julia
c = raw"C:\Users\Amministratore\Julia\myfile.jl.txt"
data = open(c,"r") do io
read(io,String)
end
@show data
```

from data give me error, goodbye.
I leave (even with others files in the folder instead of myfile, like newfile, new1 (in jl) )

ok, so you need to: [https://www.howtogeek.com/205086/beginner-how-to-make-windows-show-file-extensions/](https://www.howtogeek.com/205086/beginner-how-to-make-windows-show-file-extensions/)
again, this is why I asked you to use `tab` to complete the path, so you know what exactly IS in there.

don’t exagerate! i got the same problem with another individual between C: and D: directory so I created another folder in external drive and resolved in this mode. Ok. I can go on 😂
It’s resolved after also uninstalled/re-installed annnddd " it’s very important.
Thank’s to all. I love YOU ALL for the patience, I know tutor was a better choice…
