Unknown files in /tmp folder

I am using Ubuntu 18.04 LTE. I have recently found that there are some files that are auto created in the /tmp folder.

I am not sure what these folder/files are. They are mostly empty. If I use, Microsoft Teams, I get some additional files.

Is this good or bad?

Can anyone help me in this regard.

UPDATE

  1. I am not sure about Systemd other than reading jokes about it in Reddit.

  2. There are two folders for net and ssh namely net-export and ssh-hJ9Bd4cVFGor. The first folder is empty, while the second one is having a file agent.1454. Recently, I started using a private fiber optic network using wi-fi.

  3. I have a folder babel-q0yHwG which is also empty.

  4. When I use, Microsoft Teams folders are created for G8 Engine.

  5. Sometime, when a click a link to open a new location, a totally unwanted location is coming up.

  6. Other than that, I have Emacs temporary files, which I can understand.

Since these days, due to security concerns, I am a bit afraid as these folders were not created earlier. Most of the time, this folder remained empty unless when I open a PDF file in the browser. Hope I am able to clarify.

The `/tmp` directory is used for temporary files and the names given are usually random to ensure applications don’t overwrite existing files used by other instances. This directory is often cleaned out during reboot

Various applications use the /tmp folder to store temporary information. On Ubuntu and many other linux distributions, this directory is cleaned between reboots. So there is no need for you to worry about this folder.

Still I have a doubt for many reasons. First, I am using Microsoft Teams (I always doubt MS). Then, this systemd. I am not sure about this.

You will need to explicitly state "your many reasons" why you have doubt in your question. Please edit and elaborate on your doubts if this answer is not good for you.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
