Understanding TOS Issues


Common TOS Opening Problems

Missing The Operating System (TOS)

You attempt to load your TOS file and get an error such as "%%os%% Can't Open The TOS File Extension". Generally, this is experienced in %%os%% because The Operating System (TOS) isn't installed on your PC. The typical path of opening your TOS with a double-click won't work because %%os%% cannot make the program connection.


Tip: Another TOS-related program can be selected to open the file by clicking "Show Apps" and finding the application.


The Operating System (TOS) is Out-of-Date

It is possible that your version of The Operating System (TOS) isn't able to open your Atari ST TOS Archive File file due to incompatibility. You will need to download a newer version of The Operating System (TOS) if you don't have the right version. This problem is predominately due to having a Atari ST TOS Archive File file version that was created by a newer version of The Operating System (TOS) than what you have installed on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the TOS file, selecting "Properties", and looking at the version information.


Primarily, problems experienced when opening TOS files are due to having the incorrect version of The Operating System (TOS) installed on your computer.


More Causes of Problems Opening TOSs

You can still experience errors opening TOS files even with the latest version of The Operating System (TOS) installed on your PC. There can be external issues inside of %%os%% that are causing these errors when opening TOSs. Issues that aren't software-related:

  • Windows Registry TOS file paths that are incorrect
  • Mistaken removal of the Windows registry TOS description
  • The Operating System (TOS) or another TOS application experienced a flawed installation
  • The TOS itself is corrupted
  • Malware-tainted TOS file can't be opened
