My computer seems to lose a few gigabytes every day. How can I figure out where the new files are being created?
  There a couple ways to solve that:
  1. If you can wait until the next time free space is lost, save the current scan (Filter | Compared to Scan | Save Current Scan). At a later time, re-launch SizeTrend or refresh the current scan and compare it to the previously saved scan (Filter | Compared to Scan | Previously Saved Scans). SizeTrend will show only the difference between the current and saved scans.
  2. Look for the recently changed or created files - click "Modified in past..." or "Created in past..." button and select the appropriate time range (e.g., "7 days")). SizeTrend will show only the recent files.
   
I have received a SizeTrend license key. Where do I enter it?
  SSelect  "Help" ribbon, click "Register" button, enter the SizeTrend license key.
   
Size trend shows some files in blue. What does it mean?
  SizeTrend uses the following color scheme:
1. Blue - the file is already compressed (its compressed attribute is set) or its data is to be downloaded on demand, e.g., it is Cloud-only (iCloud or OneDrive) file that has not been locally downloaded yet.
2. Gray - a hidden file that Windows hides from the user (e.g. swapfile.sys).
