SplashTime, LaunchAppAfterSplash, and CloseEXE ignored when opening multiple files

Submitted by daniel_schaaaf on January 16, 2022 - 5:18pm

A while ago, I filed a bug report for SumatraPDF ( When I open multiple files, by marking them in Windows Explorer and pressing the Return key, SumatraPDF will overwrite its settings with a default version.

I experimented with \SumatraPDFPortable\App\AppInfo\Launcher\SumatraPDFPortable.ini and added the following parameters to [Launch]:

Running a shortcut which has parameters

Submitted by davefdm on January 7, 2022 - 9:26pm

Is there a way for the launcher to run a shortcut which has parameters?
When I double click on the shortcut it works.
When I use the PAF launcher it fails.
This is on Windows 10 Pro 21H2.
The shortcut is a ".lnk" file but Windows hides the file extension.
This is the launcher command: ProgramExecutable=V2LogCollector\log-collector.lnk

[Feature Request] Seperate folder path

Submitted by nothingness on January 4, 2022 - 8:54pm

Hi, I've been using PortableApps really useful. Recently, my C drive is getting full and I had to move some folders to D drive. Unfortunately, many portable apps eat lots of rooms, so they also have to be moved. In order to solve it, I had to install another PortableApps in D drive and it's not so pleasant.
If you add a folder path function, so I don't need to launch two PortableApps. It will be very useful. Many of the recent apps provide it and I think PortableApps also can do it.
Thanks for the wonderful app!

When "Refresh App Icons" is called, a search is made for folder.exe. If you can't find it, you should search for folder.lnk. Then I could also include installed programs in the menu. That would be great.

smaller active field requested for in Launcher

Since last update the active field around (just above the cross for leave) is much higher than necessary. So if you tab above in the grey field in order to show the launcher you get a new tab in your browser which is showing your website. Betwee "help"-button and ""-button there is enough place for clicking to show the launcher.
