-GDAL can access files located on "standard" file systems, i.e. in the / hierarchy on Unix-like systems or in C:\, D:\, etc... drives on Windows. But most GDAL raster and vector drivers use a GDAL-specific abstraction to access files. This makes it possible to access less standard types of files, such as in-memory files, compressed files (.zip, .gz, .tar, .tar.gz archives), encrypted files, files stored on network (either publicly accessible, or in private buckets of commercial cloud storage services), etc.

 Each special file system has a prefix, and the general syntax to name a file is /vsiPREFIX/...
