Script for Removing Illustrator "background" Layers from 1000+ files & then resave them to a folder

[danielj15115761]

Hello everyone!

This is my first support post. Thank you all in advance for your help and advice.

So here is our issue:

• We have 1000+ illustrator files.
• Each file has a layer with the name "background".
• We need to remove the "background" layer from the file and resave it to a folder on the desktop/or save over the original file. (whatever is easier).

My question is...is this possible with so many files?

Hi,

Try following snippet

function main() {
    var folder = Folder(Folder.desktop + "/New Files");
    if (!folder.exists)
        folder.create();
    for (var i = app.documents.length; i <= app.documents.length; i--) {
        try {
            var _backgroudLayer = app.documents[i].layers.getByName('background');
            _backgroudLayer.remove();
            var fileName = app.documents[i].name;
            app.documents[i].saveAs(File(folder + "/" + fileName));
            app.documents[i].close(SaveOptions.DONOTSAVECHANGES);
        } catch (e) {

        }
    }
}

main()

This script will create a folder on Desktop with name "New Files" and all files will be saved inside the folder "New Files"

there are over 1000 files. I don't think they will all be open in Illustrator. I have slightly modified your code

function main() {
    var folder = Folder(Folder.desktop + "/New Files");
    if (!folder.exists)
        folder.create();
    var fileList = File.openDialog("Selest Files", "All:*.ai*", true);
    for (var i = fileList.length; i <= fileList.length; i--) {
        app.open(fileList[i]);
        var doc = app.activeDocument;
        try {
            var _backgroudLayer = doc.layers.getByName('background');
            _backgroudLayer.remove();
            var fileName = doc.name;
            doc.saveAs(File(folder + "/" + fileName));
            doc.close(SaveOptions.DONOTSAVECHANGES);
        } catch (e) {

        }
    }
}

main()

OK, firstly i would just like to thank you guys for your quick replies. 

Secondly, i just got my hands on the files in question and none of them have a layer with the name "background".

But, is there a possibility to delete sub or grouped layers with the standard "<rectangle>" named layers?

Thanks in advance!!

if you need to remove the bottom layer but try this

function main() {
    var folder = Folder(Folder.desktop + "/New Files");
    if (!folder.exists)
        folder.create();
    var fileList = File.openDialog("Selest Files", "All:*.ai*", true);
    for (var i = fileList.length; i <= fileList.length; i--) {
        app.open(fileList[i]);
        var doc = app.activeDocument;
        try {
            //var _backgroudLayer = doc.layers.getByName('background');
            //_backgroudLayer.remove();
            var docLayers= doc.layers;
            var n = docLayers.length; 
            docLayers[n-1].remove();
            var fileName = doc.name;
            doc.saveAs(File(folder + "/" + fileName));
            doc.close(SaveOptions.DONOTSAVECHANGES);
        } catch (e) {

        }
    }
}

main()

if you need to delete only the bottom object, then try this

function main() {
    var folder = Folder(Folder.desktop + "/New Files");
    if (!folder.exists)
        folder.create();
    var fileList = File.openDialog("Selest Files", "All:*.ai*", true);
    for (var i = fileList.length; i <= fileList.length; i--) {
        app.open(fileList[i]);
        var doc = app.activeDocument;
        try {
            //var _backgroudLayer = doc.layers.getByName('background');
            //_backgroudLayer.remove();
            var pI= doc.pathItems;
            var n = pI.length; 
            pI[n-1].selected;
            pI[n-1].remove();
            var fileName = doc.name;
            doc.saveAs(File(folder + "/" + fileName));
            doc.close(SaveOptions.DONOTSAVECHANGES);
        } catch (e) {

        }
    }
}

main()

Getting this error message...

[pixxxelschubser]

There is a typo in the loop.

for (var i = fileList.length; i <= fileList.length; i--) {

Should be:

for (var i = fileList.length-1; i >= 0; i--) {

[danielj15115761]

Thanks for the updated code. that worked.
but when I try to select the whole folder of EPS files, i get this error now.

[danielj15115761]

Ignore the previous message. The errors came from corrupt files. The code is working perfecly.
Thank you all for your help!

[danielj15115761]

Hi Guys,

I have a question about this code. But, first here is my situation...

We have received 1000+ vector files, each with its own folder. So the vector files all need stay in this filing system. 

My question: Is there a way of updating this script to include these folders and to search for the vector files through the main folder? AND, resaving or save over the original file?

Example from the Filing System:

Main Folder > Image Folder > Image.ai

Thanks in advance for your help and feedback!

[danielj15115761]

How can I combine the below script with the script in this thread?

Any and all help is greatly appreciated.

 //   Illustrator  convert to legacy . jsx //  https :// gist . github . com / joonaspaakko / df2f9e31bdb365a6e5df //   Finds  all . ai files from the input folder +  its subfolders and converts them to the version given below in  a variable called "targetVersion"

     if   (  folder !=  null )   { 

         //  returns an array of file paths in  the selected folder . files =   GetFiles (  folder ); 

         //   This  is where things actually start happening ... process (  files ); 

     } 

 } 


 function  process (  files )   { 

     //   Loop  through the list of . ai files : 
     //   Open   >   Save   >   Close   >  LOOP for   (  i =   0 ;  i <  files . length ;  i ++   )   { 

         //   Current  file var file =  files [ i ] 

         //   Open app . open (  file );

         //   Save app . activeDocument . saveAs (  file ,   SaveOptions_ai ()   ) 

         //   Close app . activeDocument . close (   SaveOptions . DONOTSAVECHANGES ); 

     } 

     //   For  better of for  worse ... alert (   "Script is done."   ); 

 } 

 function   SaveOptions_ai ()   { var saveOptions =  new IllustratorSaveOptions (); saveOptions . compatibility =   Compatibility [   "ILLUSTRATOR"   +  targetVersion ]; saveOptions . flattenOutput =   OutputFlattening .

             //   Push  files to the array files . push (  item ); 

         } 
     } 

     return  files ; 
 } 

[danielj15115761]

Obviously, I don't need to save my files as legacy .ai. I just need to access the image files which are inside folders and subfolders.

Thanks in advance.

Hello,

I'm not sure what script in this thread you were refering to so I grabed the one that removes the bottom layer.

The script below will look in folders\subfolders for .ai files, remove the bottom layer and save over the original file(s).

function main() {

        var inputFolder = Folder.selectDialog("Select a folder to process")
         if (inputFolder != null){
        var fileandfolderAr = scanSubFolders(inputFolder, /\.(ai)$/i);
        var fileList = fileandfolderAr[0];
        }
        for (var i = fileList.length-1; i >= 0; i--) {
        app.open(fileList[i]);
        var doc = app.activeDocument;
        try {
            var docLayers = doc.layers;
            var n = docLayers.length;
            docLayers[n-1].visible = true;
            docLayers[n-1].locked = false; 
            docLayers[n-1].remove();
            doc.save();
            doc.close(SaveOptions.NO);
        } catch (e) {

        }
    }
}

main()

function scanSubFolders(tFolder, myAI) {
var sFolders = [];
var allFiles = [];
sFolders[0] = tFolder;

for (var j = 0; j < sFolders.length; j++) {
var procFiles = sFolders[j].getFiles();

for (var i = 0; i < procFiles.length; i++) {
if (procFiles[i] instanceof File) {
if(myAI == undefined) {
allFiles.push(procFiles);
}

if (procFiles[i].fullName.search(myAI) != -1) {
allFiles.push(procFiles[i]);
  }
}

else if (procFiles[i] instanceof Folder) {
sFolders.push(procFiles[i]);
scanSubFolders(procFiles[i], myAI);
    }
  }
}
return [allFiles, sFolders];
}

Regards,

Mike

Thank you Mike! Your script works perfectly.

Sorry to add another point. But, can this script be updated to include .EPS files too? 

I mean, can this script export more than one file option. We would need the following files .AI, .EPS, .PNG & .JPG

Thanks again! 

[Mike Bro]

Hello,

To inclued .eps files

//change
var fileandfolderAr = scanSubFolders(inputFolder, /\.(ai)$/i);
//to
var fileandfolderAr = scanSubFolders(inputFolder, /\.(ai|eps)$/i);

Re: the export options, you really should create a new post.

Regards,

Mike
