Editing Shapefile in QGIS. To edit a file in QGIS, firstly make sure the layer is open in QGIS! Before editing the layer need to be set as editable.

What are the supported data formats for QGIS?
Supported Data Formats ¶ QGIS uses the OGR library to read and write vector data formats, including ESRI shapefiles, MapInfo and MicroStation file formats, AutoCAD DXF, PostGIS, SpatiaLite, Oracle Spatial and MSSQL Spatial databases, and many more. GRASS vector and PostgreSQL support is supplied by native QGIS data provider plugins.
Why is my shapefile layer no longer editable?
I imported my point files as a delimininated text layer (originally) and was unable to edit. If you then save layer as a shapefile or export as a geopackage, this might help. It did for me but mine was originally a different file format I had this issue, and it was with a layer that was imported directly from a zipped folder.
Can a QGIS file contain positional information?
Such data files can also contain positional information in two main forms: QGIS allows you to load a delimited text file as a layer or ordinal table. But first check that the file meets the following requirements:
What happens if somebody edits the same feature in QGIS?
This version of QGIS does not track if somebody else is editing the same feature at the same time as you are. The last person to save its edits wins. For an optimal and accurate edit of the vector layer geometries, we need to set an appropriate value of snapping tolerance and search radius for features vertices.
How to create a shapefile in SQL Server?
SQL Server spatial query: It is possible to build a query that uses the SQLGeometry or SQLGeography data types from a relational database. An ESRI Shapefile, or just shapefile, is a file that keeps geospatial vector data format and that contains the position, format and attributes of geographic elements.
What is snapping tolerance and search radius in QGIS?
For an optimal and accurate edit of the vector layer geometries, we need to set an appropriate value of snapping tolerance and search radius for features vertices. Snapping tolerance is the distance QGIS uses to search for the closest vertex and/or segment you are trying to connect to when you set a new vertex or move an existing vertex.
How to export shapefile from QGIS to SQLite?
I would suggest to export the shapefile (s) to SQlite or FileGDB (which should perform better in QGIS). You can either do this in QGIS GUI (right click on layer a select Save As), or use OSGeo4WShell to covert using ogr2ogr, e.g. command:

How to change the style of multiple layers in QGIS?
For some older versions: You can select multiple layers in the layers list, right-click and use Paste Style from the context menu. For other older versions: The MultiQML plugin lets you apply one QGIS layer style to multiple layers at once.
Can a vector layer be edited in QGIS?
For this exercise please use QGIS version 2.18. Various vector layers and tables (OGR, SpatiaLite, PostGIS, MSSQL Spatial or Oracle Spatial) can be edited in QGIS. Before you start a editing session in QGIS, make sure you set the right snapping options ( Snapping Tolerance and Search Radius ).
