Script to save a file in a specific folder with a specific name

Question

Hello,I found a very useful script to save covers as JPEG, with a fixed width, whatever is the original size ://the export pixel width
var targetWidthPixels = 600;

var doc = app.activeDocument;
with(doc.viewPreferences){
    horizontalMeasurementUnits = MeasurementUnits.INCHES;
    verticalMeasurementUnits = MeasurementUnits.INCHES;
}

//get the page width in inches
var pw=doc.documentPreferences.pageWidth;

//calulate the resolution needed to export the jpeg as 1500px wide
//if the page is 8.5" x 11", the output pixel dimensions will be 600px x 776px
var resout= targetWidthPixels/pw;

//the active page
var pg=app.activeWindow.activePage.name;

//set the res preference and page range
 with(app.jpegExportPreferences){
     exportResolution = resout;
     pageString = pg;
     antiAlias = true;
     embedColorProfile = true;
     jpegColorSpace = JpegColorSpaceEnum.RGB;
     //add other properties as needed
}
 
//export the JPEG
doc.exportFile(
		ExportFormat.jpg,
		File(Folder.desktop + "/ExportJPG.jpg"), 
		false
);My question is : how to put this file in a specific folder (/Users/toto/Desktop/TEST MTP/OUT site) with a specific name wich is the 14 first characters of every Indesign file name (9782340-046337_COUV_2022_02_24.indd becomes 9782340-046337.jpg) Thanks for your Help

I think: var pg = 3; should work - or "3".

Hi @Stephane27925305ylf8 , you could also choose the destination folder from the script, something like this"

//Choose a folder
var f = Folder.selectDialog("Select a Destination Folder"); 
if(f != null){ 
    app.scriptPreferences.measurementUnit = MeasurementUnits.INCHES;

    //the export pixel width
    var targetWidthPixels = 600;

    var doc = app.activeDocument;
    //use the document’s name for export
    var n = doc.name.replace(RegExp('()?\.[^\.]+$'), '');

    //get the page width in inches
    var pw=doc.documentPreferences.pageWidth;

    //calulate the resolution needed to export the jpeg as 1500px wide
    //if the page is 8.5" x 11", the output pixel dimensions will be 600px x 776px
    var resout= targetWidthPixels/pw;

    //the active page
    var pg=app.activeWindow.activePage.name;

    //set the res preference and page range
    with(app.jpegExportPreferences){
        exportResolution = resout;
        pageString = pg;
        antiAlias = true;
        embedColorProfile = true;
        jpegColorSpace = JpegColorSpaceEnum.RGB;
        //add other properties as needed
    }
    //export the JPEG
    doc.exportFile(ExportFormat.jpg, File(f + "/" + n + ".jpeg"), false);
    app.scriptPreferences.measurementUnit = AutoEnum.AUTO_VALUE;
}
