+# FSBrowser readme
+
+## What is this sketch about ?
+
+This example is a FileSystem Browser for the ESP8266 using http requests and a html/javascript frontend, 
+working for both SPIFFS, LittleFS and SDFS.
+This unified version is based on the previous examples named FSWebServer, FSBrowser and SDWebServer, Copyright (c) 2015 Hristo Gochkov. All rights reserved.
+
+## How to use ?
+1. Uncomment one of the `#define USE_xxx` directives in the sketch
+2. Add the credentials of your WiFi network (search for `STASSID`)
+3. Compile and upload the sketch to your ESP8266 device
+4. For normal use, copy the contents of the `data` folder to the filesystem. To do so:
+- for SDFS, copy that contents (not the data folder itself, just its contents) to the root of a FAT/FAT32-formated SD card connected to the SPI port of the ESP8266
+- for SPIFFS or LittleFS, please follow the instructions at https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html#uploading-files-to-file-system
+5. Once the data and sketch have been uploaded, access the editor by pointing your browser to http://fsbrowser.local/edit
+
+## Options
+If you need to free some space on the ESP filesystem, you can delete all the sample files at the root but also replace the `index.htm` file in the `data/edit` subfolder by the `index.htm.gz` file from the `extras` folder. That compressed version is not suited for learning or debugging, but will bring the total FS usage under 7KB.
+If you want to use the browser on a an existing filesystem or don't want to perform step 4 above, you have two possibilities :
+- either upload the `index.htm` file to the filesystem by opening a command shell in the `data` folder and running the following cURL command:
+`curl -F file=@edit/index.htm;filename=/edit/index.htm fsbrowser.local/edit`
+- or embed a version of the html page in the source code itself by uncommenting the following line in the sketch and rebuilding:
+`#define INCLUDE_FALLBACK_INDEX_HTM`
+That embedded version is functionally equivalent and will be returned if no `/edit/index.htm` or `/edit/index.htm.gz` file can be found on the filesystem, at the cost of a larger compiled file.
+
+To regenerate the files required for the previous options or understand how they are build, see the `reduce_index.sh` script located in the `extras` subfolder.
+
+## Dependency
+The html page uses the [ace.js](https://ace.c9.io/) text editor which is loaded from a CDN. Consequently, internet access from your web browser is required for the FSBrowser editing feature to work as-is.
+If your browser has no web access (e.g. if you are connected to the ESP8266 as an access-point), you can copy the `ace.js` file (and dependencies) to the `edit` subfolder of the ESP filesystem.
+If `ace.js` cannot be found on the ESP filesystem either, the page will default to a plain text viewer, with a warning message.
+
+## Notes
+- See https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html for more information on FileSystems supported by the ESP8266.
+- For SDFS, if your card's CS pin is not connected the default pin (4), enable the `fileSystemConfig.setCSPin(chipSelectPin);` line, specifying the GPIO the CS pin is connected to
+- `index.htm` is the default index returned if your URL does not end with a filename (works on subfolders as well)
+- Filesystem limitations apply. For example, FAT16 is limited to 8.3 filenames - see https://en.wikipedia.org/wiki/8.3_filename - SPIFFS and LittleFS also have limitations, please see https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html#spiffs-file-system-limitations
+- Directories are supported on SDFS and LittleFS. On SPIFFS, all files are at the root, although their names may contain the "/" character.
+- The convention here is that the root of the filesystem is "/". On SPIFFS, paths not started with a slash are not supported
+- For creation, the convention is that a path ending with a "/" means create a folder, while without a "/" we create a file. Having an extension or not does not matter.
+
+## Changelog since original FSBrowser
+
+### Fixes to work on LittleFS based on SDFS
+- #define logic to select FS
+- switched from SD to SDFS
+- begin() does not support parameters > removed SS and added optional config
+- LittleFS.open() second parametsr is mandatory > specified "r" where needed
+- 'FILE_WRITE' was not declared in this scope > replaced by "w"
+
+### UI/usability improvements
+- Never format filesystem, just return "FS INIT ERROR" when FS cannot be mounted 
+- Tree panel width is now proportional (20%) to see long names on big screens 
+- Added icons for files, and indented them to the same level as folders
+- Changed file/folder icon set to use a lighter and more neutral one, and added specific "text" and "image" icons for formats recognized as such
+- Items are now sorted (folders first, then plain files, each in alphabetic order)
+- Added file size after each file name
+- Added FS status information at the top right
+- Made clear that an async operation is in progress by dimming screen and showing operation status
+- Filled filename box in header with the name of the last clicked file
+- Selecting a file for upload defaults to putting it in the same folder as the last clicked file
+- Removed limitation to 8.3 lowercase filenames
+- Support Filenames without extension, Dirnames with extension
+- Improved recursive refresh of parts of the tree (e.g. refresh folder upon file delete, show last folder upon creating nested file)
+- Added Save/Discard/Help buttons to ACE editor, discard confirmation on leave, and refresh tree and status upon save
+- Removed "Upload" from context menu (which didn't work anyway)
+- Added "Rename/Move" feature to context menu
+- Sketch can be used on a preexisting filesystem by embedding the index.htm file in the program
+
+## TODO (maybe)
+- ? How can we query the fatType of the SDFS (FAT16 or FAT32) to limit filenames to 8.3 on FAT16 ?
+- ? Add a visible root node "/" (with no delete option) + add the FS type next to it, like <i>LittleFS</i> 
+- ? move "Mkdir" and "MkFile" to context menu, with prompt like for Rename/Move
+- ? implement drag/drop for move + make "rename" only a local rename operation (no move)
+- ? Optionally present SPIFFS as a hierarchical FS too
+- ? Optionally mount several filesystems at the same time (SPIFFS + SDFS or LittleFS + SDFS)
+
+## Test suite
+These tests are a checklist of operations to verify the FSBrowser behaviour.

+- Icons are from https://feathericons.com/ . The resulting PNG is passed first through https://compresspng.com/ before being converted to base64 using https://www.base64-image.de/
+- The spinner is based on https://github.com/jlong/css-spinners
+- Minifiying of index.htm is done using the command line version of https://kangax.github.io/html-minifier/
+- Idea of embedding webpage in code borrowed from https://github.com/me-no-dev/ESPAsyncWebServer
