The information in this article applies to:


Pronto for Windows crashes when playing back a file with a name longer than 27 characters.


There is a bug in the filename handling in Pronto for Windows. During download Pronto for Windows creates temporary files using the names of the files from the Logger. When the file extension is added to a filename longer than 27 characters other data is overwritten and Pronto crashes either immediately or while the file is being transferred.



Upgrade Pronto for Windows to release 5.36 or later.


Rename the file in the Logger so it is less than 28 characters.

To rename a file in the Logger perform the following steps:

  • From the Logger Main Menu screen select the Explore button.
  • On the Sessions Explorer screen select the session you wish to rename from the list, then click on Rename.
  • Edit the filename as required and click on OK and then click on Back (in the top left corner) to return to the Main Menu.
