Move footage item to folder problem.

Hi,

I have a problem. I have created script with following action:

Import footage.

1. Create "_MAIN_RENDER_FX##" comp from footage.
2. Precomp footage from _MAIN_RENDER_FX## to _MAIN_COMP_FX##.
3. Add it to render queue.
4. Create "Composition" and "Footage" folder.
5. Add comp to Composition folder and footages to Footage folder.

Problem is that if I move Footages to "Footages" folder in the script and launch script again to import another footage,

It will keep in memory older footage information. If I comment that section out which moves footages to "Footages" folder it works,

It even works if I move footage to folder by hand and run script again.

My script consists three functions:

1. getInfoItem(item) // takes footage item and parse filename to different keywords.
2. findFolderItemByName(name) // this just checks that if folder exists by given name.
3. ChooseFile() // This is where we do import stuff which i explained earlier.

Can you spot mistake from my code or give some advice to improve my coding (Im quite new of scripting)? 

NOTE: This is hard coded to our project folder structure so getInfoItem function only works with this kind of folder structure.

Windows: X:\Projects\<Project>\Exports\VFX\FX##\

MAC: /Volumes/<NetworkDrive>/Projects/<Project>/Exports/VFX/FX##/

function getInfoItem(item){       // Test OS    var OS = $.os;       if (OS.search("Windows") != -1) {        OS = "Windows";        var splitNum = 4;    } else {        OS = "Mac";        var splitNum = 5;    }       //  KEYWORDs       this.fullpath = item.file;    this.fullpath = String(this.fullpath);    this.path_array = this.fullpath.split("/");       this.fxnum = this.path_array[this.path_array.length-2];     // split path based on splitNum variable which is based which OS currently in use.    this.project_array= this.fullpath.split("/",splitNum);    this.project_path = this.project_array.join("/");    // Make a COPY from this.path_array    this.path = this.path_array.slice();    // remove last cell (Filename)    this.path.pop();    this.path = this.path.join("/");    this.path = this.path + "/";          this.fps = item.frameRate;    this.duration = item.duration;    this.width = item.width;    this.height = item.height;    this.name = item.name;    this.left_index = this.name.indexOf("[");    this.right_index = this.name.indexOf("]");    this.sub = this.name.substring(this.left_index+1,this.right_index);    this.filename = this.name.substring(0,this.left_index-1);    this.splitted = this.sub.split("-");    this.first_frame = this.splitted[0];    this.last_frame = this.splitted[1];    this.ext = ".dpx"       // FOLDER RULES    var padding = "#########################";    this.aeProjectFolder = "/Project_Files/AE/";    this.renderFolder = "/Renders/VFX/"+this.fxnum+"/";       this.padnum = String(this.first_frame).length;    this.outputseq = this.project_path+this.renderFolder+this.filename+"_["+padding.slice(-this.padnum)+"]"+this.ext;    var outputfile = this.outputseq.slice(0,-this.padnum-6);    this.outputfile = outputfile + this.first_frame + this.ext;       }


function findFolderItemByName(name){
        var found = false;        for (i = 1; i <= app.project.numItems; i++){            if (app.project.item(i).name == name && app.project.item(i) instanceof FolderItem ){                var myFolder = app.project.item(i);                found = myFolder;                break                }            }        return found;


}


function ChooseFile(){


    var myItem = app.project.importFileWithDialog();       var checkFile = 1;    var footage = new getInfoItem(myItem[0]);    var rndFolder = footage.project_path+footage.renderFolder;       // Create MAIN RENDER Comp    var comp = app.project.items.addComp("_MAIN_RENDER_"+footage.fxnum,footage.width,footage.height,1,footage.duration,footage.fps);    // Check if comp or footage folder exists. otherwise create it.    if(!findFolderItemByName("Compositions")){        var compFolder = app.project.items.addFolder("Compositions");        }    else{        var compFolder = findFolderItemByName("Compositions");        }    if(!findFolderItemByName("Footages")){        var footageFolder = app.project.items.addFolder("Footages");        }    else{        var footageFolder = findFolderItemByName("Footages");        }           // Add footage to _MAIN_RENDER_FX## Comp.      comp.displayStartTime = footage.first_frame/footage.fps;    comp.layers.add(myItem[0]);      // Precomp layer from _MAIN_RENDER_FX##    var layerIndices= [1];    var precomp = comp.layers.precompose([1],"MAIN_COMP_"+footage.fxnum);    precomp.parentFolder = compFolder;    // add Comp to render Queue    rqi = app.project.renderQueue.items.add(comp);            // Find DPX template and apply    for (x in rqi.outputModules[1].templates) {        if (rqi.outputModules[1].templates[x] == "DPX" ){            rqi.outputModules[1].applyTemplate(rqi.outputModules[1].templates[x]);            rqi.outputModules[1].file = File (footage.outputseq);                     }        }                       // Put all footage items to footage folder    for (i = 1; i <= app.project.numItems; i++){            if (app.project.item(i).typeName == "Footage"){                    app.project.item(i).parentFolder = footageFolder;                }        }       
}


ChooseFile();
