# New Functionality for Moodle E-Learning Platform: Files Communication by Chat Window
## 3 Purpose of Sending Files through the Chat Window
### Analyzing the Impact of the Developed Method  
Following the implementation of the proposed solution, the following aspects were discovered:  
* The speed of information communication between students;
* Minimizing attachment transmission via other methods, such as email or online file transfer sites;
* Eliminating viruses from computers without using the internet. The proposed solution was implemented within the institution where one of the authors is employed, and the study presented in this paper was conducted on 45 users. Data collection was done through questionnaires with different questions sent and received by email and/or phone call. Data gathering was carried out over 30 days. Each participant received the questionnaires and had the responsibility to fill them in and send them on day 10, day 20, and day 30. After receiving the questionnaires in those intervals, the data were collected and centralized in a table. The 45 people from the chosen institution who participated in this study are aged between 22 and 30 years. The participants' level of knowledge and use of e-learning platforms, chat sites, and videoconferencing programs are as follows: eight beginner level, 24 intermediate level, and 23 advanced level. Every person is familiar with sending messages via chat, email, and attachments through file transfer sites. All of them accessed an e-learning platform where they participated in tests, quizzes, and conferences on different topics. The e-learning platform is usually used for posting or sending information on the main page as well as the chat window. The study carried out \begin{table}
\begin{tabular}{l c c} \hline \hline
**Chat** & **Model LMS (Web)** & **Model App** \\ \hline Send and receive messages & \(\boldsymbol{\check{\

\end{table} 
Table 2: Chat features. on the 45 students was to identify which method they prefer to use to send attachments, and which seems to be the most effective and easy to use, as can be seen in Figure 1.  
From the analysis of the obtained results, the following conclusions can be drawn: The number of users who sent attachments via chat is quite large; 37 of the 45 learners used the new method without reservations, thus proving the interest, usefulness, and efficiency of this implementation. The number of users who sent attachments via email decreased significantly, from 25 to three. The number of users who have sent attachments when registering for a course or webinar decreased significantly, from eight to two. The number of users who sent attachments via file transfer sites dropped significantly, from five to one. The number of users who sent attachments via document sharing dropped significantly, from seven to two. When attachments were sent through the chat solution, the number of viruses transmitted through attachments decreased from three to zero. Thus, a decrease in interest and the number of those using the old solutions was observed in favor of the newly implemented solution. The evaluation aimed to determine user satisfaction with the new solution implemented on a sample of 45 users for 30 days. In addition, in parallel with these actions, a controlled work environment was created, with about 400 users who used the new method for 3 months. During this time, integration of the new solution into the Moodle platform was monitored, as well as the operating and loading parameters and the technical and functional parameters of the components in the system architecture. The platform's IT administrators in a Windows Server 2022 operating system environment on which the deployed client is installed executed the test parameters. Access to it was offered from workstations configured with Windows 8, 8,1, 10, and 11 operating systems.
