File Manager

File Manager

Accessed from Utility > File Manager. Browse, view, and manage files on the active storage (SD if present, otherwise LittleFS). Directories are listed first, then files, both sorted alphabetically. The title bar shows the current folder name (or File Manager at the root).

Operates on Uni.Storage — the same primary storage used by every other module. Renames, deletes, and pastes affect real files. There is no undo.

Browser Controls

Input	Action
UP / DOWN	Move selection
Press (Select)	Open folder, or open text viewer for files
Hold Press 1s	Open the context menu for the highlighted item
Back	Go up one folder; exit when already at /

Folder navigation remembers the selected row at each level (up to 8 deep), so going Back returns the cursor to the folder you came from.

Context Menu

Hold the select button for one second over a row to open the per-item menu. Available entries depend on whether the target is a file, a directory, or empty space, and whether the clipboard holds an item.

Entry	Shown when	Action
View	File	Open the text viewer (scrollable, ASCII)
View HEX	File	Open the hex viewer (offset · bytes · ASCII)
New Folder	Always	Prompt for a name and create it in the current folder
Rename	File or directory	Prompt for a new name
Delete	File or directory	Delete the file, or recursively remove the folder
Copy	File	Stash the file path with a Copy clipboard tag
Cut	File	Stash the file path with a Cut clipboard tag
Paste / Replace	Clipboard set	Copy or move the clipboard item into the current folder; label flips to Replace if a same-named file exists
Clear Clipboard	Clipboard set	Drop the clipboard item without acting on it
Close	Always	Return to the folder listing
Exit	Always	Leave the File Manager

Copy reads the source file content and writes it to the destination, so it works across SD ↔ LittleFS even though rename does not. Cut uses rename, which is fast but stays on the same filesystem.

File Viewers

Text viewer loads the file into RAM and splits it on newlines. Use UP / DOWN to scroll, Back to return.

Hex viewer streams the file from storage in fixed-width rows (8 or 16 bytes per row depending on screen width) and shows the offset, hex bytes, and printable ASCII for each row. Scroll a row at a time with UP / DOWN; Back returns to the file list.

Very large files (logs, captures, firmware blobs) can be slow to open in the text viewer because the entire file is loaded into RAM. Prefer the hex viewer for binary or multi-megabyte files.

Storage

The File Manager works on whatever path Uni.Storage is rooted at — typically:

/                         (root of SD or LittleFS)
└── unigeek/              project files written by other modules
