M Editor Lite

You can do the work you have been doing on the PC with the terminal you are using now.

During the move? Travel destinations? My home at the end of work?
Do you need a PC even in such a case?

Edit files, create directories, preview files, get website source code, code scraping (by jQuery), JSON data analysis, file output (in mail etc.)

FTP connection is not possible with this lite version.

What file extension can I create?

Newly created text file
html, css, js, json, txt, xml, cgi, php, pl, py, rb
However, files downloaded by FTP with paid version can be edited with the same extension.
In addition, the image file corresponds to jpg, png, gif.
