This was added/fixed in Nov 2024 for the MSI of version 5 to match the portable version 4, but now with the Portable version 5 it doesn't have the same feature as the MSI. See the original idea below.
Portable Version 4 appends the computer name to the end of the log files. Which keeps all the logs together when viewing files in alphabetical order. But now Portable Version 5 puts the computer name at the beginning (Prefix only) of the log file name so now logs files are all over the place when viewing in alphabetical order.
Please add the option to Append computer name to the logs to Portable Version 5 to match MSI version 5 and portable version 4.
