I’v tried your approach, it didn’t work as I expected.
in the dialogbox of ‘Find in Files’, the edit for ‘In Folder’ only can accept a path of folder but a file, If I specify a single file as the path to find files in, it find nothing…
in addition, the result list from ‘Find in Files’ have many other info such as ‘F:testtest.txt(32):’, but I only want the one I wanted.
