- remote file listings
- read/write operations
Current listing flow uses `remote_dirlistfm`, where agent filenames are treated as exact values and preserved by the Panel.
## User Workflow
- browse files
- upload/download
- edit common configs
Special-character names are supported end-to-end in browse/navigation/actions, including:
- `@3739421199`
- `@CF`
- `My Mod Folder`
- `[Server] Configs`
- `profile.backup`
- `mod+keys`
## Admin Workflow
- set file management permissions
@ -43,9 +54,22 @@ In-panel file manager and file editor for customer server homes.
- protected control files
- shared secret exposure
Path safety model:
- Preserve exact filename display and action values (no destructive filename stripping).
- Escape output for HTML rendering only.
- Encode filename tokens in links using `rawurlencode`; decode with `rawurldecode`.
- Reject invalid path components (`..`, path separators, NUL byte).
- Normalize relative paths and verify final resolved paths remain inside the assigned game home.
- Distinguish user-facing errors:
- `Server files have not been installed yet.` (home missing)
- `Directory not found: <relative path>` (missing subdirectory)
- `Directory exists but cannot be opened. Check permissions.` (listing/access failure)
- `Path decode failed` (invalid filename token)
## Known Issues
- should be hardened around safe roots and backups
- very large uploads/downloads still depend on chunking/browser limits
## Missing Functionality
