   # Bug Report
   
   ## Problem
   Downloaded files disappears after few weeks
   ### What is expected to happen?
   Downloaded files stays on the persistent storage permanently on both Android and iOS platforms.
   
   
   ### What does actually happen?
   Downloaded file is not found after several days or weeks.
   
   
   ## Information
   <!-- Include all relevant information that might help understand and reproduce the problem -->
   I have downloaded PDF files from a website and then store the locations of the filenames on the local storage. Then I use FileOpener plugin to open PDF files. After few weeks, the file-opener does not find some of the downloaded files and throws file not found error. I'm assuming the phone OS is removing the files for not being used frequently. I'm experiencing this issue for nearly 6 months or so. Please see the code snippet I use to download a pdf file.
   
   
   ### Command or Code
   <!-- What command or code is needed to reproduce the problem? -->
     private downloadPDF(pdf: IPdf, callback: (data) => void) {
   
       const fileTransfer: FileTransferObject = this.transfer.create();
   
       fileTransfer.download(pdf.Location, this.file.dataDirectory + pdf.Name).then((entry) => {
   
         if (this.platform.is('android')) {
           this.filePath.resolveNativePath(entry.toURL())
             .then(filePath => {
               callback(filePath);
             })
             .catch(err => console.log(JSON.stringify(err)));
         }
         else {
           callback(entry.toURL());
         }
   
       }, (error) => {
         // handle error
       });
     }
