Overview:
On a MetaDefender Drive, when running MetaDefender Drive In-Session Scan, there is a message saying Low Disk Space
In some cases, the root cause of it is because engines folder are taking up space, like in this screenshot, ESET database is occupying 2.94GB.
Solutions:
Create a .cmd file with following content
@echo off
setlocal EnableDelayedExpansion

rem Remove-DatabaseFolders.cmd
rem Recursively finds all folders named "database" under
rem .\CTR\engines and deletes them.

rem Usage:
rem Remove-DatabaseFolders.cmd (asks for confirmation)
rem Remove-DatabaseFolders.cmd /y (no prompt)
rem Remove-DatabaseFolders.cmd /list (dry-run, list only)
rem Remove-DatabaseFolders.cmd "C:\other\root" (custom root)
rem Remove-DatabaseFolders.cmd "C:\other\root" /y (custom + no prompt)

:usage
echo Usage:
echo %~nx0 - prompt before deleting under .\CTR\engines
echo %~nx0 /y - delete without prompting
echo %~nx0 /list - list matches only, do not delete
echo %~nx0 "C:\path" - use a custom root folder
echo %~nx0 "C:\path" /y - custom root, no prompt
exit /b 0
Copy the script to /MetaDefender Drive (disk-label):/tools then run the script from there
Say "y" (yes) when asked and your disk space is reclaimed.
Launch Drive In-Session again and let it download needed data
