I already mentioned this topic from this thread (I Need the Support for Opening the Applications in the Directory).

In the classic operating systems like Windows 95 and Windows 3.1, the classic operating systems do not need to have the spaces for the names of the directories. That includes opening the applications in the Command Prompt program. The Powershell Prompt, the Task Scheduler, and the Run Dialogue application work the same as the Command Prompt.

Example 1
If I use the Command Prompt program to open an application, "C:\ThisApplication\ClassicApplication.exe", it works. Because, there are no spaces for the names of this directory.

Example 2
If I use the Command Prompt program to open an application, "C:\This Application\Classic Application.exe", it does not work. Because, there are a few spaces for the names of this directory.

Example 3
If I use the Command Prompt program to open an application, "C:\This_Application\Classic_Application.exe", it works. Because, there are a few underscores for the names of this directory.

The older operating systems, including the older applications, do not need to have the spaces. Instead, they do need to have the underscores. It is like creating a bridge between the factory workers and the product sellers. It is also like letting the ants with the food walk across the bridge from a hill to another hill.

Many people missed playing the classic applications as well as the classic games. That includes the classic PC games that are made for the older operating systems. Many people know that there are the classic PC games that can still be played on the classic operating systems, but some people can play the classic PC games with the emulation techniques on the modern operating systems.

The underscores can create the bridges. The underscores can create the paths. The underscores can show the computer users the ways.
