ActionScript 2.0 :: Create Txt File To Be Stored On Clientside?

I would like to know whether is it possible to create a text file that contains some variables or strings that will be stored on the users pc (client side)? I have a button on my e-learning website that will launch an exe(located on user's computer). When the exe is launched, the user is required to record and save his audio on his computer. When the user clicks on the save button on the exe, the user has the option to save the audio on any folders and any name of their preference. This part of development is done. However, I would like to create a 'default' file name whereby the user can either use the default name or change the file name themselves. When the user navigate to other lessons and click to save the audio recorded, the default file name will change according to the unit/activity name. Therefore, I personnally think that the way to make this realise is to pass a tag/variable/text file from the flash. The exe file will read the file names from the tag/variable/text file and display a different default name for each different page on my site.

Example: When user save an audio on unit S35PE12 (unit/activity name), the flash will pass this value(S35PE12) to the exe. If the user is saving an audio from unit L23PE41, the value being passed to exe will be L23PE41.
