Hello!

Problem is that Rename files -action creates a list of files.

And when your second Rename file(s) -action tries to rename the file it gets a list value when it should get string of the file path. So you need to refer to the %R000% -variable as %R000[0]% to get the first list item (in your case there will always be just one list item since it takes just one per loop).

Also since your Current item is File-type variable with different properties you want to use "NameWithoutExtension" or in the second Rename file(s) action toggle off "Keep exension" (otherwise it will rename the file "Test Name.Txt.txt")

Try like so:

Hope this helps!

@eetuRobo Thanks for helping.

My challenge is that I'm unable to understand how to add properties to these. If I type manually, it gives error.

Please advise.

Thanks a lot 🙏

Like so:
%R000[0].NameWithoutExtension%

Since the R000 is a list you need to tell it which item you are referring to. So in your case the R000 list will always have just one item so you reference the first item which is index zero %R000[0]%. Then add dot and the property "NameWithoutExtension".

Sometimes PAD also knows to give them to you in the variable selection when you expand the CurrentItem

You could also do the flow like this. I tried to explain in red text what the actions do:

Copy the actions to your flow:
Display.SelectFileDialog.SelectFiles Title: $'''Choose Files''' InitialDirectory: $'''C:\\Users\\x''' IsTopMost: False CheckIfFileExists: False SelectedFiles=> SelectedFiles ButtonPressed=> OpenFiles File.RenameFiles.RenameReplaceText Files: SelectedFiles TextToReplace: $'''_''' ReplaceWith: $'''%' '%''' IfFileExists: File.IfExists.DoNothing RenamedFiles=> R000 SET oNames TO R000 IF OpenFiles = $'''Open''' THEN LOOP FOREACH CurrentItem IN oNames Text.ChangeCase Text: CurrentItem.NameWithoutExtension NewCase: Text.CaseOption.TitleCase Result=> nName File.RenameFiles.Rename Files: CurrentItem.FullName NewName: nName KeepExtension: True IfFileExists: File.IfExists.DoNothing RenamedFiles=> R002 END END
