Files Stored in Windows C Drive Taking Up Excessive Space

I need guidance\support. My Windows C drive is showing it is running out of space. Given the space allocation, I questioned how could that even be possible. The culprit is:

C:\Users[username]\AppData\Local\Plex\Plex Media Server.\Synch.\2\6\Chicago Fire (2012)\Season x

I have Plex running on my NAS and those same files are in a Plex Media folder on the NAS. In the setup of Plex, I will admit many months ago I wanted to be able to view Plex content on my Windows but the actual Plex Server is on the NAS. I realized I did not need “Plex Media Server” on my Windows PC just to open the Browser and watch content on my Windows PC. I thought I had removed all content but clearly I did something to cause some folder for a specific show to exist. I checked the Windows Apps and it does not show any Plex Media Server.

I expect it may be related to the incident where I noted Chicago Fire was missing different episodes in various seasons. I noted the problem when using the Windows browser and I saw a download option. I clicked on that link thinking it would search for missing content (older season and missing episodes) and it did not find the missing episodes. I moved on thinking I will just have to get over the fact they are missing and watch what it recorded.

Now that I see the files saved on my Windows C drive and the same content on my NAS in the Plex Media server, it must have downloaded the content to my C drive.

The question is can I delete the content on C driver? What is the reference in the file structure with a folder called “Synch.” What is it synching? My concern before deleting is it synching with the NAS drive too? Should I just delete all folders under Plex in the structure above?

I need to recover almost 118GB of space on my Windows PC so those files have to go.

Thanks for any suggestions.

That is the download location for Plex for Windows Desktop.

To remove the files, delete them from the Downloads library. See the Cancel or Delete a Download section of Downloads for Windows, macOS, Linux Desktop.

Thank you. I should have dug deeper. Much appreciated!
