Google File Stream - Large Cache With No 'Offline' Files

Hey guys, so hopefully someone can help me here. 

I first uploaded all of my files (about 300GB worth) using Google Backup And Sync. Then I uninstalled Backup and sync, and deleted the copies on my hard drive to save space. 

Then I installed Google File Stream - I have access to all my uploaded files without those files having to take up space on my hard drive.  

- I haven't UPLOADED any new files since installing google file stream. \
- All of my files are 'online only' I haven't yet synced anything to be available offline
- I have been using a lot of the files over the past few days, as well as browsing through directories checking everything is properly uploaded.

Now, When I look at my cache, it is 22GB in size. 

So my question is: 

1) What is taking up all that space in my cache? I presume when I use a file that it downloads the file, then keeps that file in cache? 

2) Does that cache automatically clear at some point?  

Having a cache that's constantly growing as I use it (if it never clears its cache), without having any files on offline mode seems to defeat the purpose of google file stream in the first place.

Hi Damien,

We can only provide general guidance and support here at the G Suite Help Forum. As your issue may require advanced troubleshooting to diagnose, I’d encourage you to contact the G Suite tech support department here so that they can assist further.

You can also clear the app cache by completing the following steps:

1. Click on the Drive File Stream icon in your task bar.

2. Sign out and then click on the icon again and click ‘Quit’.

3. Uninstall Drive File Stream.

4. To locate the cache of the application, go to this location:

Windows: %USERPROFILE%\AppData\Local\Google\DriveFS

Mac: ~/Library/Application Support/Google/DriveFS

5. Delete the Google Drive folder entirely.

6. Reinstall Drive File Stream from here.

This is the frustrating thing at times - When google support can't clearly provide an answer and assumes it's something wrong with you. 

SO, I called google directly and dug down until I found someone who COULD provide what should be a relatively simple tech question. 

My computer isn't doing anything strange in need of troubleshooting. 

Google File Stream will keep a cache of all files you use (even if they are set to online mode), until such time as your cache reaches 20% of the free space on the drive, then it will start deleting cached files to keep the file size at 20% of free space.  It won't, of course, delete any cached files that are set to 'offline mode'. 

Alternatively, any time you want to clear your cache completely, simply log out of google file stream app, and logo back in. 

I don't know exactly why Google Advisor couldn't answer this question, and I don't know why it was so hard to obtain, but at least now future users can find the answer here.
