8. Panoul Navigatorului
Panoul Navigatorului QGIS este un instrument excelent pentru navigarea, căutarea, inspectarea, copierea și încărcarea resurselor QGIS. Doar resursele pe care QGIS știe să le gestioneze sunt afișate în browser.
Folosind panoul Navigatorului puteți localiza, inspecta și adăuga date, așa cum este descris în Panoul Navigatorului. În plus, panoul Navigatorului acceptă glisarea și plasarea multor resurse QGIS, cum ar fi fișierele de proiect, scrípturile Python, scrípturile de procesare și modelele de procesare.
Scrípturile Python, scrípturile și modelele Processing pot fi, de asemenea, deschise pentru editare într-un editor extern și în modelatorul grafic.
Puteți trage și plasa straturi din panoul Straturi în panoul Navigatorului, de exemplu într-un GeoPackage sau o bază de date PostGIS.
Fig. 8.1 Panoul Navigatorului
Panoul navigatorului (Fig. 8.1) are o ierarhie extensibilă, cu câteva intrări fixe de nivel superior care organizează resursele gestionate. Intrările nodurilor sunt extinse făcând clic pe 
din stânga numelui intrării. Orice ramură este restrânsă făcând clic pe 
. Butonul |colapseTree| Restrânge Tot restrânge toate intrările de nivel superior.
În este posibilă dezactivarea resurselor. Dacă, de exemplu, nu doriți să afișați scrípturi Python în browser, puteți debifa intrarea , iar dacă doriți să scăpați de folderul de casă din navigator, puteți debifați intrarea .
(
Filtrarea Navigării) poate fi folosită pentru căutarea pe baza numelor intrărilor (atât intrările subordonate, cât și intrările nodurilor din ierarhie). Folosind meniul derulant 
Oțiuni de lângă câmpul de text al filtrului, puteți
efectua Căutare Senzitivă
seta Sintaxa modelului de filtrare la

Controlul grafic al Proprietăților, care arată informații utile despre unele intrări/resurse, poate fi activat/dezactivat folosind butonul |metadate| Activează/dezactivează controlul grafic al proprietăților. Când este activat, se deschide în partea de jos a panoului navigatorului, așa cum se arată în Fig. 8.2.

A second browser panel can be opened by activating the Browser (2) panel in . Having two browser panels can be useful when copying layers between resources that are locationed deep down in different branches of the browser hierarchy.
8.1. Resources that can be opened / run from the Browser
A lot can be accomplished in the Browser panel
Add vector, raster and mesh layers to your map by double-clicking, dragging onto the map canvas or clicking the
Add Selected Layers button (after selecting layers)Run Python scripts (including Processing algorithms) by double-clicking or dragging onto the map canvas
Run models by double-clicking or dragging onto the map canvas
Extract Symbols… from QGIS Project files using the context menu
Open files with their default applications (Open <file type> Externally… in the context menu). Examples: HTML files, spreadsheets, images, PDFs, text files, …
Copy entries
Rename and delete (multiple) layers (context menu: )
Open a file explorer window and directly select the file Show in Files
Resource specific actions are listed for the different resource groups sorted under the top-level entries listed below.
8.2. Browser panel top-level entries
8.2.1. Favorites
Often used file system locations can be tagged as favorites. The ones you have tagged will appear here.
In addition to the operations described under Home, the context menu allows you to Rename Favorite… and Remove Favorite.
8.2.2. Semne de Carte Spațiale
This is where you will find your spatial bookmarks, organised into Project Bookmarks and User Bookmarks.
From the top level context menu, you can create a bookmark (New Spatial Bookmark…), Show the Spatial Bookmark Manager, Import Spatial Bookmarks… and Export Spatial Bookmarks….
For bookmark group entries you can Export Spatial Bookmarks…, create a bookmark (New Spatial Bookmark…), Rename Bookmark Group, and Delete Bookmark Group.
For bookmark entries you can Zoom to Bookmark, Edit Spatial Bookmark… and Delete Spatial Bookmark
8.2.3. Project Home
Available once the project file has been saved, the Project home entry is a folder containing data and other contents (scripts, models, text, …) that may be used within the current project. Displayed in the Browser panel, it allows you to quickly access data and other files of the project.
It defaults to the project file folder but can be changed through the option, or by right-clicking on the Project Home item of the Browser panel and selecting Set project home…. Customizing that folder is especially useful in contexts where QGIS projects are not stored in the root folder of an organisational «project», along with datasets.
8.2.4. Drives and file system
The next items of the Browser panel depend on the OS in use and concern the top level entries of its file system.
They are mainly:
The Home folder, pointing to the current user home folder
on Unix-based machines, the root / folder
the connected drives, either local or network. Depending on the OS, they are directly listed (eg,
C:\,D:\) or through the/Volumesentry.
From the contextual menu of each of these folders or drives, you can:
refresh the contents
create a subitem that is a Directory, GeoPackage or ESRI Shapefile format dataset
hide the directory (Hide from Browser)
Set color: customize the folder icon color, aiding in rapid browser navigation of complex folder structures
enable Scanning:
Monitor for changes: allows to manually control
whether a particular directory should be monitored and automatically updated.
This setting applies to the selected directory and all subdirectories.
This means that you can manually opt-in to monitoring of network drives
if you know there’s no issue, or manually opt-out of monitoring of large
directories which you don’t want monitored for other reasons.
By default, remote or network drives are not automatically monitored.
Fast scan this directory
open the directory in your file manager (Open Directory…)
open the directory in a terminal window (Open in Terminal…)
inspect the Properties… or the parent Directory Properties…
8.2.5. Database entries
Depending on your OS and installed drivers, you might have access to different database types to use in QGIS. Below are listed the different entries of contextual menu at each level of the dataset tree.
