I think to use text files with a slider, they either need to be in the exact same folder as the JS plugin (I think REAPER actually looks there first) or in the DATA directory.

I just always use the DATA directory cause I know where to find it

Here is a working JS plug example that just displays the context of the text files. The user will have to provide the files of course

slider1:/text files:none:Text File 

@init

//FUNCTIONS for reading .txt files
//offset = starting string number
//returns number of lines read

function file_to_numbered_strings(file,offset)local(handle)
//this version can be used when you define the file via ~ filename:0,sometext.txt at the beginning of your code
//use slider version if you want to pick from text files in a folder
(
  handle=file_open(file);
  file_string(handle,offset);  
  while( strlen(offset) && offset < 1023 )
    ( offset+=1;
      file_string(handle,offset);      
    );
  file_close(file);
  offset;
);  


function slider_file_to_numbered_strings(slidernumber,offset)local(handle,lastvalue,lines)
//USE ONLY THE NUMBER OF THE SLIDER FOR "slidernumber"  - do not use "sliderx"
(

  slider(slidernumber) != lastvalue ? reload=0;
  
  !reload ? (
    handle=file_open(slider(slidernumber));
    file_string(handle,offset);  
    while( strlen(offset) && offset < 1023 )
      ( offset+=1;
        file_string(handle,offset);      
      );
    file_close(file);
    lines=offset;
    lastvalue=slider(slidernumber);
    reload=1;
  );
  lines;
); 
  

  
@slider
lines=slider_file_to_numbered_strings(1,offset);

//some guidance
gfx_setfont(1, Ariel,14);
gfx_x=40; gfx_y=10;
gfx_r=gfx_g=gfx_b=1;
gfx_drawstr("Create a folder in your REAPER Data directory named \"text files\", then create or put some .txt files in the folder.
The text within those files will be displayed below when selected by the slider");


//display file
gfx_setfont(2, Ariel,18);
gfx_r=1;gfx_g=gfx_b=0;

yy=55;
gfx_x=xx;gfx_y=yy;

loop ( lines,
  
  gfx_drawstr(i);
  gfx_x=xx;
  gfx_y+=gfx_texth+3;
  i+=1;
);

*When working with .txt files like this and something seems to disappear, the file might not have been closed properly. OFFLINE the plugin and bring it back if something goes awry.
