Description of the Issue

Having replaced stock notepad with notepad++ in registry according to the docs, selected formats open in notepad++ v8.4.8 but now additionally display a Cannot open file " ". (whitespace within doublequotes) error.

This can be observed by doubleclicking .ps1 powershell files, or opening registry .reg files with the Edit action in the file context menu. Other file formats defaulting to Edit on open may be affected as well. Standard .txt files, as well as files potentially associated with (windows) notepad by the user (for example .cfg, .json , .log, .xml ...) are unaffected.

Steps to Reproduce the Issue

1. Replace notepad with notepad++ in registry according to the documentation
2. Create a dummy test.ps1 or test.reg with any content
3. Doubleclick test.ps1, or rightclick->Edit test.reg

Expected Behavior

File opens (notepad++ <=v8.4.7)

Actual Behavior

File opens, but a Cannot open file " ". message box is displayed first (notepad++ v8.4.8)
