Hey @ArtiSta

That is Know thing.

Just Use Trim with your file name while using it with start process activity.

String File_path_variable = “D:\Test.pdf”;

in Start Process - File_path_variable.Trim();


Hi @aksh1yadav

Thanks for the hint, but unfortunately it didn’t solve the issue.
I also tried replacing whitespaces with %20 but it didn’t work either.


It should work . it worked for me many times. faced same issues.

Can you share the path ? which is creating prob for you?

e.g. “C:\My Company\Invoice 1708057.pdf”

Trying to find the problem I changed the folder name to MyCompany and removed the spaces from the file name and it worked fine. For any pdf with whistespaces in the path (no matter if the white spaces are in the folder name or file name or both), Acrobat is unable to open the file.

Please find the xaml file I have used to open pdf file. It works.3.xaml (4.3 KB)

Oh, well. Never thought of using the file path as execulatble path … To easy to be true :wink:
Thanks, @BikashPanigrahi.

In the meantime I just resolved the problem with placing the file path in the arguments section - all I needed to do, was to place the path in another pair of double-quotes (e.g. Chr(34)+“C:\My Company\Invoice 1708057.pdf”+Chr(34)).

Thanks for help guys!
