In NPM 10.5 and less, all reports for Report Writer are stored in the filesystem at \Program Files (x86)\SolarWinds\Orion\Reports. After 10.6 the web reports are stored in the database in addition to the report Writer files as mentioned before.
Hope this helps
I see, will check it later. Are those reports updated? Since what I do is open report writer, click each one, then query, then I export them to pdf, which is very tedious considering I'm only using remote server and the response is slow.
