Sign in to saveAlso known as ESRI Shapefile
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. The shapefile format can spatially describe vector features: points, lines, and polygons, representing, for example, water wells, rivers, and lakes. Each item usually has attributes that describe it, such as name or temperature.

Shapefile file extensions—ArcMap | Documentation
The shapefile may appear as a single file in ArcGIS, but on disk it is composed of several files organized in a workspace. Each file extension represents specific information.
desktop.arcgis.com →Shapefiles are a simple, nontopological format for storing the geometric location and attribute information of geographic features. A shapefile is one of the spatial data formats that you can work with and edit in ArcGIS. The shapefile format defines the geometry and attributes of geographically referenced features in three or more files with specific file extensions that should be stored in the same project workspace. They are: .shp—The main file that stores the feature geometry; required. .shx—The index file that stores the index of the feature geometry; required. .dbf—The dBASE table that stores the attribute information of features; required. .sbn and .sbx—The files that store the spatial index of the features. .fbn and .fbx—The files that store the spatial index of the features for shapefiles that are read-only. .ain and .aih—The files that store the attribute index of the active fields in a table or a theme's attribute table. .atx—An .atx file is created for each shapefile or dBASE attribute index created in ArcCatalog. ArcView GIS 3.x attribute indexes for shapefiles and dBASE files are not used by ArcGIS. A new attribute indexing model has been developed for shapefiles and dBASE files. .ixs—Geocoding index for read/write shapefiles. .mxs—Geocoding index for read/write shapefiles (ODB format). .prj—The file that stores the coordinate system information; used by ArcGIS. .xml—Metadata for ArcGIS—stores information about the shapefile. .cpg—An optional file that can be used to specify the codepage for identifying the characterset to be used. Each file must have the same prefix, for example, roads.shp, roads.shx, and roads.dbf. When viewing shapefiles in ArcCatalog (or any ArcGIS application), you will only see one file representing the shapefile; however, you can use Windows Explorer to view all the files associated with a shapefile. When copying shapefiles, it is recommended that you do so in ArcCatalog or by using a geoprocessing tool. However, if you do copy a shapefile outside ArcGIS, be sure to copy all the files that make up the shapefile.

شيب فايل هو صيغة شعاع بشكل رقمي بهدف تخزين الموقع الجغرافي وربطها بمعلومات. هذه الصيغة تقلل حجم تخزبن المعلومات الطبوغرافية.شيب فايل استخدم وصنع اولا في برنامج Arcview GIS ويستخدم أيضا في برنامج Arc Info ،Arcgis ويستخدم أيضا بشكل واسع في برامج ال GIS شيب فايل فعال جدا لانه يخزن المعلومات الجغرافبة الأولبة للنقاط والخطوط والمضلعات.هذه العناصر كلها في الواقع غير مفيدة إذا لم تقرن بمعلومات خاصة تمثل هذه العناصر. لذلك فان كل سطر بالجدول مرتبط بعنصر في الشيب فايل. الاشكال مثل (نقاط خطوط مضلعات) مع بعضها يمكن ان تمثل معطيات جغرافية. وهذا التمثيل الجغرافي يعطينا إمكانية إجراء حسابات دقيقة وفعالة.
