ទិដ្ឋភាពទូទៅ
Bulk-exports the vector layers of the current project to GeoPackage, Shapefile, GeoJSON, KML or CSV, and pulls layers out of any vector file back into the project — in one window, with a tick box per layer.
QGIS can export one layer at a time through Export > Save Features As. This is the same job for twenty layers, with renaming on the way out and a single output folder. Because the window is modeless you can drag a file straight from the Browser panel onto it.
The tool is promoted onto the KGA toolbar as its own button.
ប៉ារ៉ាម៉ែត្រ
The algorithm takes no Processing parameters — running it opens the window. The controls below are the window's.
Tab 1 — Export Layers
| ផ្ទាំងគ្រប់គ្រង | ប្រភេទ | តម្លៃលំនាំដើម | ការពិពណ៌នា |
|---|---|---|---|
| Project layer table | Checkable table | nothing ticked | The vector layers in the QGIS Layers panel. Columns: Layer, Geometry, Features, Export As. Export As is editable, so you can rename on the way out. Double-click a row to toggle it. |
| Select All / Clear All | Buttons | — | Tick or untick every row. |
| Refresh from Layers Panel | Button | — | Re-read the Layers panel after adding or removing layers in QGIS. |
| Output Format | Combo box | GeoPackage | GeoPackage (.gpkg) — all layers in one file; ESRI Shapefile (.shp), GeoJSON (.geojson), KML (.kml), CSV (.csv) — one file per layer. CSV writes attributes with geometry as WKT. |
| GeoPackage File | Text box | export_layers.gpkg | Name of the single output container. Only shown for the GeoPackage format. |
| Output Folder | Read-only path box | empty | Where everything is written. Set it with Browse Folder. |
| Export selected features only | Checkbox | unticked | Exports the current map selection of each layer instead of all its features. |
| Overwrite layers that already exist in the target (otherwise a numbered name is used) | Checkbox | unticked | Off, a name clash gets a numbered suffix rather than replacing anything. |
| Export Checked Layers | Button | — | Runs the export and reports a summary. |
Tab 2 — Import Layers
| ផ្ទាំងគ្រប់គ្រង | ប្រភេទ | តម្លៃលំនាំដើម | ការពិពណ៌នា |
|---|---|---|---|
| Source File | Read-only path box, drop target | empty | The file to read. Drag a .gpkg, .shp, .geojson, .kml and so on here from the Browser panel, or use Browse File. |
| Layer table | Checkable table | nothing ticked | The layers found inside the source. Columns: Layer, Geometry, Features, Add As. Add As is editable, so you can rename on the way in. |
| Select All / Clear All | Buttons | — | Tick or untick every row. |
| Rescan File | Button | — | Re-read the source after it changed on disk. |
| Add the imported layers to the project | Checkbox | ticked | Untick to scan without loading anything. |
| Reproject to the project CRS on import (creates a memory layer) | Checkbox | unticked | On, each layer arrives reprojected — as a memory layer, so save it if you want to keep it. |
| Import Checked Layers | Button | — | Runs the import and reports a summary. |
របៀបប្រើ
To export:
- Open KGA Data Management > Layer Export / Import, or press its button on the KGA toolbar. Close the Processing window once the pane appears.
- On 1. Export Layers, tick the layers. Edit the Export As cell to rename one on the way out.
- Choose the Output Format. GeoPackage puts everything in one file; the others write one file per layer.
- Set the Output Folder with Browse Folder, then press Export Checked Layers.
To import:
- Switch to 2. Import Layers.
- Drag the source file onto Source File from the Browser panel, or use Browse File. The layers it holds are listed.
- Tick the ones you want, edit the Add As names if needed.
- Tick Reproject to the project CRS only if you need it — the result is a memory layer you will have to save.
- Press Import Checked Layers.
លទ្ធផល
- Export: the ticked layers written to the chosen folder — one GeoPackage holding all of them, or one file per layer for the other formats. A summary message box lists what was written, skipped and failed.
- Import: the ticked layers added to the project, renamed as you asked, optionally reprojected.
Nothing is returned to Processing.
កំណត់សម្គាល់ និងដែនកំណត់
- The window stays open. Close the Processing dialog behind it and keep working. Running the tool again while the window is open brings it forward; running it after you closed it starts clean, with the ticks, output folder and scanned file cleared.
- Reprojected imports are memory layers. They disappear when the project closes unless you save them to a file.
- Styles do not travel here. This tool moves data. To carry symbology, labels, aliases and forms along, use Spatial Data Manager (its Export tab writes styles into the target) or Create Layer Package.
- Shapefile output truncates field names to 10 characters; CSV output keeps attributes only, with the geometry as a WKT column.
layer_stylesandqgis_projectsare QGIS housekeeping tables and never appear in the import list.- The tool cannot run headless or inside a model — it needs the QGIS main window.
