Thank you @sambilanet, Yes you are right but these happen only when the file is in the same folder. What about searching inside folders ( folders inside folder) ?
Example: Lets suppose that we have a hierarchical structure of folders from 1 to 5.
I want to search on folder 3 that has 2other folders inside it.
When i search for a file it appear only the file on folder 3. The other files are mixed and not sorted. These is my problem. I want to find on my search all files in folder 3,4 and 5. ( Like explorer on windows)
So is that possible?
