This tool allows browsing littlefs disk images from within your web browser.

Click here to use the most recent version of this application.

This application implements an emulated block device for littlefs, which has been compiled to WebAssembly. By only loading the parts of the disk image that are currently used by littlefs, almost arbitrarily large disk images can be loaded without requiring much memory. By default, the application caches up to 1 MiB of data in memory and allocates 64 KiB of memory for the littlefs implementation.

This web application requires a modern web browser to work. If you are using an older web browser, please update your browser before filing a bug report.

This tool does not support the old file system structure that was used by older versions of littlefs. Try using lfs_migrate to convert your disk image to the new file system layout before attempting to mount it.

While most options can be determined automatically, the block size cannot. If mounting fails or directory contents are not displayed correctly, please ensure that you entered the correct block size for the disk image you are trying to mount.
