Fix export path resolution to prevent "Access denied" errors on C:\ drive
Shipped in Margin Master 2026.901.28986 · September 1, 2026
Fixed a critical bug where export operations could fail with "Access denied" when the default export path setting was missing or blank. All import and export operations now consistently resolve to C:\MarginMaster (or the configured path) instead of sometimes defaulting to the C:\ drive root, which standard users cannot write to.
What changed
Export path now resolves consistently across all operations
Exports that previously failed with "Access denied" will now succeed. The export path shown in Options will match the path actually used by all export operations.
Export error messages now include the full file path and reason
Bare drive roots (C:\) rejected as import/export folders
Centralized import/export path resolution logic
