We are pleased to present the latest release of our well-known file tree editing tool File Tree Express. This intuitive tool was designed to ease the everyday work with smart cards and their contents.

One Product – Two Versions

File Tree Express R2.1 supports GSM and UICC technologies along with SIM, R-UIM, USIM, CSIM and ISIM applications. Depending on your testing needs, you can choose between two different versions: File Tree Express Basic R2.1 and File Tree Express Professional R2.1.

File Tree Express Basic R2.1 offers functionalities like Scan, Edit, Find, Copy and Save file trees.

Choose the basic version, if you want to change the contents of a data field or if you want to create your own file trees in an easy and convenient way.

File Tree Express Professional R2.1 combines the functionalities of the basic version with special features such as:

  • EF Translator
  • File Tree Compare
  • Command Sequencer
  • APDU Viewer
  • Create/Delete/Resize File
  • Excel Import and Export
  • UXP/SIMpml Import and Export
  • Create Personalization Scripts


The New Professional Version – Opening New Testing Possibilities

The EF Translator transforms the data of an Elementary File into human-readable form. To quickly find a specific file, you can search with the file name, file ID, file description or with parts of the translation. Customers who work with different cards will appreciate the “File Tree Compare” functionality that compares different file trees and highlights the differences.

You can also create your own scripts, which is a valuable feature when it comes to performing multiple actions on the card. The scripts can be stored and executed whenever needed. The listing of commands for different applications will help you to create the scripts according to your needs. It is also possible to create a personalization script that automatically updates the data of relevant EFs. You can execute the script in the “Command Sequencer”.

If you want to see what happens in the background, the “APDU Viewer” of the professional version traces all commands passing the interface, which helps you to check if the commands have been executed correctly. When creating a new DF or a new data field, several different attributes have to be considered. The “Create” functionality guides you smoothly through the creation process. Furthermore, you can use the “Resize” command to extend the size of a data field. As it is sometimes indispensable to print out the contents of a scanned card, the new File Tree Express Professional also offers the possibility to export the file trees into an Excel sheet.
