FB File Complications


Common FB Opening Problems

Slim! is Not Installed

Double-clicking your FB file prompts the message "%%os%% Can't Open FB File". Customarily, this means that Slim! is not installed on %%os%%. This will prevent you from double-clicking to open the FB file because the OS doesn’t know how to handle it.


Tip: When another FB application is installed, you can choose to open it by selecting "Show Apps" and using that program.


Slim! is Out-of-Date

It is possible that your version of Slim! isn't able to open your Slim! Compressed Archive file due to incompatibility. Download the latest Slim! version from the Serge Voskoboynikov website to ensure you have the correct one installed. The primary cause of this problem is that your Slim! Compressed Archive file was created by a different (newer) version of Slim! than what's installed.


Tip: If you right-click on your FB file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Conclusion: The majority of FB file opening issues are due to not having the correct Slim! version installed.


More Causes of Problems Opening FBs

Errors opening Slim! Compressed Archive files can still occur even with the latest Slim! software installed on your computer. Other FB opening errors can be created by other system problems inside of %%os%%. Additional factors include:

  • Incomplete or bad installation of a software application associated with the FB format
  • FB file corruption
  • Your FB is infected with malware
