Files
Browse, preview, edit, upload, download, and delete files inside volumes and running containers.
Use the Files browser the same way whether you are inside a volume or inside a running container.
Entry points
Open the Volumes page, select a volume, and click Browse. The route looks like /volume/<name>/browse.
Open a running container, then click Files or open /file directly. Stopped containers do not expose a writable file browser.
Navigation
Use the tree on the left to move through folders, the breadcrumb at the top to move up, double-click folders to descend, and Back or Home for quick jumps. The path input jumps straight to a known path.
Preview files
Added in v4.4.0.
Preview opens common file types without downloading first.
| Type | Formats |
|---|---|
| Text and code | .txt, .log, .json, .yaml, .toml, .ini, .env, source code files |
| Markdown | .md, .mdx |
| Images | .png, .jpg, .jpeg, .gif, .webp, .svg |
.pdf | |
| Video | .mp4, .webm |
| Audio | .mp3, .wav, .ogg |
Files larger than 10 MB are download-only so Dockerman does not load the whole file into memory.
Edit files
Added in v4.4.0.
Open text and code files in Monaco, make your changes, then save them back to the volume or container. Unsaved changes stay visible until you save or discard them.
Editing a file inside a running container changes the container's writable layer, not the image. Restarting from the same image discards the edit unless you commit the container first; see Inspect, clone, and commit.
Editor safety guards
- Mode preservation — saving a file keeps its original Unix permissions (
0644,0755, etc.) instead of resetting them on write. - Binary detection — the editor refuses to open a file that contains a NUL byte and shows a download prompt instead, preventing accidental corruption when an extension is misleading.
- 1 MB edit cap — files larger than 1 MB are read-only in the editor. Download, edit locally, and re-upload when you need to make a bigger change.
Upload and download
Use the explicit upload actions to choose a local file or folder and add it to the current directory. Download is available for individual files. The current browser does not advertise drag-and-drop upload, multi-file download, or automatic folder ZIP download.
Delete files
Added in v4.4.0.
Delete removes the selected file or folder from the current volume or container.
File deletion is irreversible and bypasses any host recycle bin.
Delete operates on the selected entry. The current browser does not provide the documented multi-select shortcut set or batch deletion.
