This parameter determines the parent of the dialogs created by finder:get-file, finder:put-file, finder:common-get-file, finder:common-put-file, finder:common-get-file-list, finder:std-get-file, and finder:std-put-file.

> parameter (finder:default-extension) → string?
> (finder:default-extension extension) → void?
> extension : string?

This parameter controls the default extension for the framework’s finder:put-file and finder:get-file dialog. Its value gets passed as the extension argument to put-file and get-file.

Its default value is "".

> parameter (finder:default-filters) → (listof (list/c string? string?))
> (finder:default-filters filters) → void?
> filters : (listof (list/c string? string?))

This parameter controls the default filters for the framework’s finder:put-file dialog. Its value gets passed as the default-filters argument to put-file.

Its default value is '(("Any" "*.*")).

This procedure queries the user for a single filename, using a platform-independent dialog box. Consider using finder:put-file instead of this function.

Queries the user for a filename.

If the result of (preferences:get 'framework:file-dialogs) is 'std this calls finder:std-put-file, and if it is 'common, finder:common-put-file is called.
