What is "%TEMP%\Encoding Time.csv" on Windows?

Question

Does anyone know what app is writing to file "%TEMP%\Encoding Time.csv"? The file is constantly growing. Searching Internet did not yield any meaningful results. Below is an example of the records in the file.

I did trace it to Skype. In my case it wasn't even running. But would autostart and run for about 20 secs and then close. I have no idea what it was doing or why it needed to write this strange file. Smells fishy to me – Lester

I've this file created sometimes in C:\Temp – Slapbang

Answer 1

I have also come across this file, I discovered it is created by Skype for Business by deleting the file and having it re-create during a skype video meeting. I'm not sure why it is created or how to disable it though.

Skype (not Skype for Business) can create it too in C:\Temp. – Bots

Skype have been uninstalled from my laptop and this file is still created there. It comes from Microsoft Teams. – Slapbang

Answer 2

Seems like Microsoft Teams can create this too (since the video conference is based on Skype). This showed up for me after I set a custom background.
Sample line:

0x0000024088504A10, 37960914834869640, 204351, 204361, 10, 1920x1080

The last column is the dimensions of the background image.

I just noticed this today, sounds like a debug file from developers to create it if you have a temp folder on C – Launcher

I've also this file created in c:\temp and I've Teams on my computer. – Coacervate

Answer 3

The "Encoding Time.csv" is created by Skype and/or Microsoft Teams. It appears to be some kind of debug information for video/screen rendering.

It is safe to delete manually, or can also be removed during Disk Cleanup if "Temporary Files" is checked.
