 If you don't want to show any dialog and you know for sure where you want the files saved, you can save with absolute paths while setting [ `IfShowFileDialog` ]({{site.info}}api/WebTwain_IO.html#ifshowfiledialog) to `false` .
 
 > When using an absolute path, you must make sure the current user has the proper permission to save to that path. Otherwise the save will fail.

-In [WASM browsers]({{site.getstarted}}platform.html#wasm-browsers), `DWT` runs its entire operations within the browser. So saving locally triggers will instead download the file and [ `IfShowFileDialog` ]({{site.info}}api/WebTwain_IO.html#ifshowfiledialog) will have no effect.

 ### Save multiple files to the same location

+
+In [WASM mode]({{site.indepth}}features/initialize.html?ver=latest#webassembly-edition), `DWT` runs its entire operations within desktop/mobile browsers. As a result, files are always saved in the system's Downloads folder by default, regardless of the absolute path specified. And the API [ `IfShowFileDialog` ]({{site.info}}api/WebTwain_IO.html#ifshowfiledialog) has no effect in WASM mode.

+// The following line will be ignored and 
+// no file dialog will be shown in WASM mode
