Batch convert eps files to CMYK

@gabriellecdon 

Try following snippet

var folder = Folder.selectDialog("Select folder");
if (folder != null) {
    var _files = folder.getFiles("*.eps")
    for (var f = 0; f < _files.length; f++) {
        app.open(_files[f]);
        app.executeMenuCommand('doc-color-cmyk');
        app.executeMenuCommand("save");
        app.executeMenuCommand("close");
    }
}

Before running this, you can keep your all eps files in one folder and choose the folder after running the script. The above script will open each eps file exists in the folder and convert to cmyk, save and then close it.

hey @gabriellecdon  try this

var doc = app.activeDocument;
var cntDocs = app.documents.length;
for(i=0;i<=cntDocs -1; i++){
    app.executeMenuCommand('doc-color-cmyk');
    app.executeMenuCommand("save");
    app.executeMenuCommand("close");
}

You can create an action while recording the open, convert and save process and use Batch from the Actions panel menu to play it on a folder of .eps files.
