Quick start
You can be looking at a tokenised, filtered project blob in under a minute. The two paths below cover almost every use.
Path 1: local files
- Open fileconcat.com.
- Drag a folder or file selection onto the drop zone on the landing page. The workbench takes over.
- Watch the file tree populate. Tick or untick individual files; the token counter in the ActionBar updates live.
- Click Copy or Download in the bottom ActionBar to take the output with you. Copy is single-file only; for multi-part output use Download.
Path 2: remote source
- On the workbench, paste a GitHub, GitLab, Bitbucket, Gist, or any other URL into the Source input.
- The tabs above the input auto-switch to the matching adapter (toggleable in Advanced if you prefer a fixed default).
- Click Fetch Files. The tree populates the same way as a local drop.
- Filter and emit as in Path 1.
Filter and emit
Both paths share the same workbench from this point on:
- The FilterRail on the left holds the include and ignore textareas and a row of preset chips for common stacks.
- The ActionBar Options popover at the bottom holds the single-vs-multi format choice, the XML-vs-Markdown style choice, and (when multi is active) a chunk-size input.
- The bottom-of-rail Advanced disclosure holds line numbers, max file size, and the default remote source setting.
