{%snippet file-system-create-folder%}

The following example writes some text to a file. It will create a new file or overwrite an existing file. {%snippet file-system-write-string%}

{%snippet file-system-create-file%}

{%snippet file-system-get-folder%}

{%snippet file-system-read-binary%}

Each app has several well known folders. This is how to access them: {%snippet file-system-known-folders%}

Getting all files and folders within a folder: {%snippet file-system-folders-content%}

Getting all folder entities in array may be slow with large number of files. Enumerating the folder entities would iterate the files one by one without blocking the UI. {%snippet file-system-enum-content%}

{%snippet file-system-parent%}

{%snippet file-system-extension%}

{%snippet file-system-fileexists%}

{%snippet file-system-folderexists%}

{%snippet file-system-renaming%}

{%snippet file-system-renaming-folder%}

To 'delete', 'remove' or 'unlink' a file use the file's remove method: {%snippet file-system-remove-file%}

{%snippet file-system-remove-folder%}
