This is a notepad application having the encryption function. This treats plain text without decorations and saves it as the file.

This supports two cipher text file types ([.chi] and [.vnlt]), and the clear text file type [.txt].
The file type [.chi] is the Blowfish encryption compatible with Tombo and Kumagusu. The file type [.chs] is not supported.
The file type [.vlnt] is the Base64 encoding after the AES encryption. The help document includes the source code of encryption and decryption.
The text is stored as files in hierarchized folders located in the exclusive area of this application which is invisible from outside.
Default character set is UTF-8. The type [.chi] supports UTF-8, Shift_JIS, and UTF-16LE. The type [.txt] supports more character sets.
The character set can be detected automatically at reading a file (It is not perfect. If failed, disable the detection in settings).
This has the viewer mode and the editor mode. The text is un-editable in the viewer mode and is editable in the editor mode.
This has text search function in the viewer mode and the editor mode.
This has undo and redo functions in the editor mode. This presents the selection of save or discard when closing the editor mode.
This supports many functions (copy, delete, rename, share, make-folder, export, import, backup and restore) in the filer mode.
This can sort the file list by file name, file size, update time, and file type.
The deleted files are held in the trash can and are deleted automatically after specified period (default 30 days). The deleted files can be put back.
To avoid repeated input, the encryption password is held in the application during a specified time (default 3 minutes).
Though default is plain text, but the Markdown or HTML interpretation result is shown in the viewer mode, when the setting is changed.
