Re: Launch() Function

Hi @CNT ,

Do you want to open a local html file by using launch control?

I’ve made a similar test,but it didn’t work.The formula is as follows:


I’ve searched related information. I’m afraid that the function of using the Windows file server path by launch control within PowerApps has not yet been implemented.

The launch function is used to open a webpage or an app.It can only use URL temporarily.

I suggest you to express your views on PowerApps Ideas Forum. Your precious advice will be very helpful for our work.


As an alternative solution, you could store the files within your Cloud service, such as, OneDrive, Dropbox, etc. Then use Launch function to open the file based on the file link.

For example,I’ve uploaded a html file to my OneDrive. Click on the html file in OneDrive to see its url(https://.....).

The Launch function I used as below:


then it works.

Thanks @FlexmindTeam and @v-yutliu-msft for your suggestions.

Yes, this feature is just not supported. PowerApps team have to add it in the future.


I have made a new idea suggestion,
