If you prefer not to install third-party software, Windows provides two built-in ways to adjust file attributes:

File Explorer Properties: Right-click any file, select Properties, and toggle basic flags like Read-only or Hidden at the bottom of the General tab. This method is simple but must be done manually or in small groups.

Command Prompt (attrib): Open the Command Prompt and use the attrib command for batch changes. For example, running attrib +h +r “C:\path\to\folder*.*” /s will instantly apply both Hidden (+h) and Read-only (+r) attributes to all files in that directory and its subfolders. If you want to choose the right option, let me know:
