Thank you for the ini files.
The ini files are the same.
For 6.7 million files, Everything should be using about 670 MB if you just index filenames, size and date modified. (default indexing options)
You are indexing every basic property under Tools -> Options -> Indexes.
Are you using these indexes? -If not, please disable them.
RAM usage for each setting:
Index Recent Changes: 25MB per 1million files changed.
Journal will use the specified maximum size. (10MB in your case)
Index file size: 8MB per 1million files.
Fast size sort: 8MB per 1million files.
Index folder size: 8MB per 1million folders.
Index date created: 8MB per 1million folders.
Fast date created sort: 8MB per 1million folders.
Index date modified: 8MB per 1million folders.
Fast date modified sort: 8MB per 1million folders.
Index date access: 8MB per 1million folders.
Fast date access sort: 8MB per 1million folders.
Index attributes: 4MB per 1million folders.
Fast attribute sort: 8MB per 1million folders.
Fast extension sort: 8MB per 1million folders.
These will add up quickly for 6 million files. (~500MB)
I see you are indexing several properties.
You will see the following RAM usage for the following:
Aspect Ratio: 4MB per 1million video files.
Audio Bit Rate: 4MB per 1million video files.
Audio Channels: 4MB per 1million video files.
Audio Format: varies, about 18MB per 1million video files.
Available Free Disk Size: 8MB per 1million folders.
Dimensions: 8MB per 1million video files.
Length: 8MB per 1million video files.
Size on Disk: 8MB per 1million files.
Total Bit Rate: 4MB per 1million video files.
Total Disk Size: 8MB per 1million folders.
Used Disk Size: 8MB per 1million folders.
Video Bit Rate: 4MB per 1million video files.
Video Format: varies, about 13MB per 1million video files.
Fast sort for each setting: 8MB per 1million files. (this alone is 624MB)
where video files is: *.mkv;*.mp4;*.avi;*.iso
These will add up quickly for 6 million files. (~739MB)
The actual data is not much (139MB), its the fast sort that will use the most RAM here.
I see you are indexing content.
Content indexing may consume large amounts of RAM.
I don't recommend indexing over 1GB of text content.
Please try the following search:
content: addcol:a a:=LEN($content:) sort:a-descending
Examine values in column A
This value is the indexed content size for each file.
Please make sure there's no really large files. (over 100MB)
-Maybe you are indexing a log file?
-Maybe Everything is reading a binary file as text?
Ideally, the text content should be under 1MB for each file.
Reduce the number of files you are content indexing with content indexing filters under Tools -> Options -> Content.
