Why is it dangerous to edit the config.sys file with h a word processor?

Editing the config.sys file with a Word processor can be dangerous because these programs often add formatting characters or metadata that can corrupt the file. Such alterations can lead to the system being unable to read the file properly, resulting in boot failures or system instability. Additionally, Word processors may not preserve the plain text format required for configuration files, further risking data integrity. It's safer to use a plain text editor designed for code editing to avoid these issues.
