Sequence FM version 6.0 released

Sequence FM version 6.0 has been released.

The code is available on Sequence FM´s Github page.

Below, a list of changes is presented.

New very important keys:

  • Control (Ctrl), is now a key for selecting objects for copying/moving/deleting.
  • ESC is now a buffer cleaner: Control adds files to the buffer (to wait for actions); ESC clears this buffer.

New integrated features:

  • Delete key support
  • Delete multiple objects
  • Trash support added.(trash folder will be created inside user´s home directory)
  • Move multiple objects.
  • Copy multiple objects.
  • Statusbar added.
  • Permanent delete support added.

Notice that if you move, copy or trash a file that already has an identically named counterpart on the upcoming location, you will end up loosing the older object (present before your actions) from the upcoming location.

Removed features:

  • Direct terminal command support: This came out looking like a potential security issue. It was removed from the Gui but remains as a possibility within the code.

Sequence FM 5.0 arrives. This filemanager is made with Python3 and QT5. It intends to be a simple and lightweight.

On Github:

Currently functioning features include:

  • Terminal command support in addressbar: You can, for example, type firefox and it will start after you press Enter and then press Control from your keyboard to execute.
  • General addressbar funtionalities: Showing current location and navigating to current location via addressbar.
  • Open file with application functionality.
  • Make a new text file functionality.
  • Make a new folder functionality.
  • Object renaming is supported.
  • Open archive, compress an object or extract an archive is supported via file-roller integration.
  • Right-click menu: Almost all the above functionalities have been placed inside the right-click menu of Sequence FM.
  • Preliminary shortkey support: Delete button of a keyboard will launch object deleting functionalities. Control button will execute terminal command from addressbar – after first validated with Enter keypress.

Error handling inside Sequence FM has been improved – to avoid accidental crashing-

To use Sequence FM you should have, at least, these installed (Debian base as an example):

sudo apt-get install python-pyqt5 python python3 file-roller

Default locations: You can place Sequence FM in any location. I recommend /usr/share/


If needed make python files executable: chmod +x

Run with: python

About delete, copy and moving functionalities.

I decided to keep this filemanager as unix like as possible. As I prefer terminal commands, I left out move,copy or removal commands. I believe those are best served via terminal client. See here for more:

Sequence FM v.4.1 & Gtk-Tools v.1

14th of July 2017: Sequence FM v.4.1 and Gtk-Tools v.1:  Download as a zip package.

This is a bug fix release for Sequence FM. Now the file manager can open files with external programs like it should. An added feature to this release is the terminal command support. If you write: firefox, albix, vlc (or some other program name) to the address bar and press enter then the program will open up. You can also use other terminal commands like rm -r to remove files or folders. Be cautious with terminal commands and use them only if you know what you are doing.

Older post from 2nd of June.

Here is Sequence FM v.4. Code is now a lot cleaner and minimized to (about) 189 lines. In this release I placed resources under their own respected menus and also made right-click menu layout clearer.

Also, a notable change happened to copy, paste, move and delete functionalities. The previous now have their own program: Gtk-Tools, which is dedicated to handle those actions. Gtk-Tools is made out of the old Crosslinker FM code and thus it might seem familiar.
