Welcome to the Pixel Manager, a lightweight console based file manager for Linux systems! This has been developed as a part of the CS 301 Operating Systems Course, IIT Gandhinagar by Arpita Kabra, Devvrat Joshi, Viraj Shah and Vrutik Shah.
The main features of the Pixel Manager are:
- File System Management
- Built-In Terminal
- Built-In File Editor
- Quick File Search
- Clone this repository
git clone https://github.com/devvrat-joshi/Pixel-Manager.git
- Navigate to the folder
cd Pixel-Manager
- Run
makeThis will automatically install dependencies as well as run the pixel manager. In case make does not work. Try running
python3 main.py
- If it runs into any error, try running
Ctrl + cto restore into normal state. Run it again to exit from the File Manager!

The main window of the File Manager provides an easy way to navigate through any files and directories on the system. The left panel shows the contents of the current directory, and highlights the selected content with green color. The center panel is for search window and shows the contents of the selected directory (if not a file). The right panel shows stats of the selected file/directory along with CPU and RAM usage. Here is the preview of the main window:
Navigate using the arrow keys! Right key opens to the selected directory and left key moves back to the previous directory.
The bottom row bar displays all the possible commands to copy, move, delete and create new files and folders, search through directories, and start the Terminal!
The built-in terminal can be toggled by pressing Shift+TAB
It can run all Linux commands and system calls. It can also execute user defined programs. However, it does not support interactive programs yet.
Here's a preview of how it looks:
The input can be given at the bottom most line and the output will be presented in the Terminal Output panel. The terminal panel becomes orange if your program is still executing. The terminal also supports scrolling if the output is more than the screen size.
To edit files on the go, navigate to the file and pressing e would open the file in the built-in editor. The editor is line-by-line scrollable and we have made sure to handle several corner cases that may arise.
The current editor is customized for python files, highlighting keywords, adding indentation spaces and auto-completing brackets and strings.
The editor currently also supports cut/copy/paste and find-replace utilities. Following are the screenshots for the same.
To enable the search bar, enter ctrl + a. It initiates a trie creation from the current folder in a different process. As soon as the trie is created, it is returned to the main process (the File Manager) to initiate the search. Larger the folder size, larger the size of the trie and more RAM used for storing. However, once created, the trie is stored for further use in Pickle File format which uses very less space and saves trie creation time!
Here is a preview of search!
The top bar shows the trie creation process!
Here is how searching looks:
It can search for thousands of files giving results instantly. Scroll and navigate through the found items. The search_files folder stores the pickle files created after intiating search.
When searching, top right corner shows the number of search results. Scrolling through the search results and then pressing enter will take you to the paths on which the actual file/folder is present.
After pressing enter on one of the paths, you will be redirected to that location.
