Very slow portable app to access a folder

shakolan Jan 31, 2018 4:52 AM

Hi everyone!

I'm new in creating portable applications so this might be a newbie question.

I've created a portable app of an application which saves files on the pc. When the file is saved and displayed as completed, if i right click on the item there is an option to access the folder where the item is saved. When i do this, it takes over a minute to just open the folder.

When i try this with the installed application, it opens the folder instantly.

I am using Windows 10 Enterprise. I also tried this on the virtual machine and it still have this issue. When accessing folders through the app, it is extremely slow and sometimes it even crashes.

Anyone knows what might be the issue? What do i need to change in Package.ini to fix this?

Thanks in advance!

What a isolation mode do you use in application?
I had very slow responses when there was bad isloation mode and lots of directories were isolated. Also registries.

In package.ini i'm using Isolation level - Merged.

Regarding the thread i couldn't find a way to fix it there. I 've also asked about it but didn't get a response.

Even if it opens a folder and then i close the application entirely , because the folder was open through the application is slow until i close it and open regurarly the folder from the file explorer.

Any ideas?

Thanks for the response!

i guess you are referring to this solution :

have found partial solution.
ExternalCOMObjects={18907F3B-9AFB-4F87-B764-F9A4E16A21B8}
This parameter in package.ini speed up folder listing to 9-11 seconds.

However what id should i use in ExternalCOMObjects ? I'm not sure i understand exactly this parameter and how to use it

I have tried to make a portable app using Cameyo and Spoon Studio and i can access folders through the app instantly but with thinapp it takes 1 minute.

I'm using a windows 10 vm with thinapp. Will something change if i use an older operating system such as windows 7 or 8?

I can also provide the app which is a small app and you can try it your self and see if the same issue reproduces
