Hi,   
  
 if the filename of a FB project is e.g. something like “my-new-project.fb8” the filename of resulting log and lock files is “my\_new\_project.\*”.   
  
 For names of FB log and lock files then the underscore is used.   
  
 That is bad if you e.g. have to clean up a directory after a FB Build. You have to use exceptions in a script to handle this.   
  
 Regards,   
 Thomas   
  
 We use Windows 10 Professional and the actual FB version 8.0.0.2412.

Hi Thomas   
  
 I agree, not sure why it was done like this, I suspect perhaps the logging engine didn’t support - at some point, however I just tested it and it does. In the next update, if there isn’t already a log file with \_ then a new one will be created with - if the project file used -   
  
 Once you have the next update, you can either delete the existing log files, or rename them to use - and they will work.
