Recently, I have noticed a lot of language.bin files on my system after using Tor for a while. The process I implement after closing Tor (or any other program, being VPN or direct connection) is to clean the system of any residual file. I have recently noticed the following files after closing Tor on my system: Arabic.bin, Czeck.bin, Danish.bin, Dutch.bin, English.bin, . . . etc., (Total of 24 language.bin files).
I don't feel comfortable about this; specially since it is somthing that didn't happen previously. Is there somthing wrong going on? For what purpose the files being injected into my system? Does fingerprinting going on?

Those *.bin files do not belong to the Tor Browser Bundle (TBB). I downloaded the latest version of TBB and the only two files which had bin in their names were:

  • bing.xml
  • toolbar_button_binding.xml

Those *.bin files seem to come from some sort of audio driver (maybe Realtek audio). The poster in this thread recommends to disable the onboard audio. The thread also has some more recommendations. However the *.bin files are surely not Tor related.


The bin files in the Temp folder are generated by RtHDCpl.exe from Realtek.

  1. Print msconfig in the run command.
  2. select the start page and remove the mark at RtHCCpl
