You generally don't have to worry about any of this, but it does keep things cleaner. Mostly just a few of the more complex TYPO3 projects have been affected.

* On some configurations of Docker Desktop for Windows, symlinks are created in the container as "simulated symlinks", or XSym files. These are special text files that behave as symlinks inside the container (on CIFS filesystem), but appear as simple text files on the Windows host. (on the CIFS filesystem used by Docker for Windows inside the container there is no capability to create real symlinks, even though Windows now has this capability.)
* DDEV-Local attempts to clean up for this situation. Since Windows 10+ (in developer mode) can create real symlinks, DDEV-Local scans your repository after a `ddev composer` command and attempts to convert XSym files into real symlinks. It can only do this if your Windows 10 host is set to Developer Mode.
* On some older configurations of Docker Desktop for Windows, symlinks are created in the container as "simulated symlinks", or XSym files.

Since Windows 10+ (in developer mode) can create real symlinks, DDEV-Local scans your repository after a `ddev composer` command and attempts to convert XSym files into real symlinks. On older versions of Windows 10, it can only do this if your Windows 10 workstation is set to "Developer Mode".
* On Windows 10+, to set your computer to developer mode, search for "developer" in settings. Screenshots are below.
