Wdc
~/.wdc is a hidden WD Discovery data folder used by Western Digital software to store user-level app data and related configuration files.
What is Wdc?
~/.wdc is a hidden folder created by WD Discovery on macOS. WD Discovery is Western Digital desktop software used with supported external drives and related WD utilities. This folder stores user-level app data that WD Discovery uses while installed, and users commonly encounter it when checking hidden files or cleaning up software leftovers. On Mac, Western Digital's removal steps specifically list /Users/USER_NAME/.wdc among the items to delete when fully uninstalling WD Discovery. Removing the folder while WD Discovery is still in use can interrupt the app's settings or related drive-management functions. If you no longer use WD Discovery or other WD components that depend on it, this folder is usually optional.

Safety overview
Status: Mostly safe
This folder is associated with legitimate Western Digital software. Its presence matches WD Discovery's documented macOS files, and deleting it is part of Western Digital's full uninstall process. The main risk is functional rather than security-related: removing ~/.wdc can reset WD Discovery data or affect companion WD tools that were installed through it. If WD Discovery is still installed, quit it first and keep the folder until you finish uninstalling the software.
Recommendation: Keep ~/.wdc if you still use WD Discovery, WD Drive Utilities, or other WD software installed through that environment. If you have already removed WD Discovery or no longer use WD management features for your drive, you can delete ~/.wdc as part of cleaning up leftover data. If you want a complete cleanup, remove it after uninstalling WD Discovery and then restart your Mac.
