rimraf: Windows file deletion tool

When using degit to download files, you often encounter the problem that you need administrator permission to delete files, and even if you run as an administrator, it may be invalid. At this time, rimraf can be easily solved. Why?

rimraf is a recursive deletion tool based on Node.js. The reason it is efficient on Windows is that it directly calls Node.js' file system module (fs) to perform the underlying file system operations. rimraf uses Windows junction points and re-resolving points to bypass some Windows permission checks.

Files downloaded by degit may have special attributes or permissions, resulting in the normal deletion operation requiring additional permissions. rimraf directly operates the file system and ignores these special properties, thereby realizing deletion.

In addition, rimraf will try to delete files multiple times, and if the first time fails, it will try other methods, such as changing file permissions or adjusting permissions using the icacls command, improving its adaptability in various deletion scenarios.

Therefore, rimraf can efficiently delete files under Windows, mainly because it utilizes the Node.js file system module and Windows-specific technologies, bypassing regular permission checks and file attribute settings. When encountering similar problems, you might as well try rimraf , it may have surprise effects.
