ScsSubst
ScsSubst is a Windows utility that maps local folders to custom drive letters for shorter paths and AI workspace isolation.
ScsSubst maps local folders to Windows drive letters without duplicating files. It helps users shorten long project paths and isolate AI tool workspaces to specific drives. The software runs locally using system application programming interfaces without bundling third-party file system drivers. It provides options for automatic startup, multiple server mappings, and administrator visibility. The product is designed for Windows 10 and 11 users who manage deep directory structures.
