How does NetLogo work with folder and directory path?

[Rafaela Lorena]

Hello,

I have a question about how I should use NetLogo and folder organization.

I have a model that takes several .asc files from a folder called "layers" and generates several .csv outputs. This folder "layers", the model in .nlogo and the outputs to be generated are inside a folder called "working" which in turn is on the desktop of my notebook (my system is Windows 10 Home 64 bits). I have 2 weeks trying to resolve an error that appears in the code that s:

The file C:\Users\rafa\Desktop\working\file_Landscape3_EVI1_seed1.csv cannot be found
error while turtle 652 running FILE-PRINT
  called by procedure OUTPUT
  called by procedure DIEPROC
  called by procedure GO
  called by Button 'Go'

However, this error above is meaningless, because in the "working" folder the file is open there waiting to be filled with data. So, by chance, yesterday, I decided to copy this "working" folder from the desktop and put it in the C directory and simply ran the model without any error!!!!

So, I have the following questions:

1) Is there any way to fix a directory in NetLogo? I saw it has the set-current-directory string. And then I had one more doubt, every time I open the model I will have to specify the path, correct?

2) Is there an ideal way to name folders?

3) Is there a better directory that I should use to run NetLogo, i.e. is it better to use C than desktop?

4) Why did the model run in C and not run and show the above error when the "working" folder is on the desktop?

I would like to note that I am a computer architecture layman and a NetLogo beginner. So sorry if I was redundant or if I said something nonsense. It's just that I got confused and I'd like to understand and solve this dilemma :) lol

Below, a part of code:

extensions [ gis ]
globals [
  Resources
  Landcover
  RandomSeed
  NumResourceFiles
  NumLandscapeFiles
]

patches-own [
  resource-value
  habitatcover
]


to setup
  clear-all
  set RandomSeed 1
  random-seed RandomSeed
  set NumResourceFiles 1
  set NumLandscapeFiles 1
  prepare-output
  setup-layers  
  reset-ticks
end

to prepare-output
  if output? = true ;; output: is switch in interface
  [
    let numLand word "_Landscape" NumLandscapeFiles
    let numResource word "_EVI" NumResourceFiles
    let numSeed word "_seed" RandomSeed
    carefully
    [ file-delete ( word outfile numLand numResource numSeed ".csv" ) ] ;; outfile in a input interface (string). tnhe name used "file"
    [ ]
    file-open ( word outfile numLand numResource numSeed ".csv" )
    file-print ( word "id,distance_traveled" )  
    file-close
  ]
end

to setup-layers
  let num NumLandscapeFiles
  let num2 NumResourceFiles

  set Resources gis:load-dataset ( word "./layers/L" num "_EVI0" num2 ".asc" ) ;; examples of name files: L1_EVI01.asc L2_EVI01.asc L1_EVI02.asc
  set Landcover gis:load-dataset ( word "./layers/L" num "_MAP.asc" ) ;; examples of name files: L1_MAP.asc
  gis:set-world-envelope gis:envelope-of Resources
  gis:apply-raster Resources resource-value
  gis:apply-raster Landcover habitatcover
 ; color-Resources
 ; color-map
end

Thanks in advance!!!
