can't choose file from Default folder

I see in the backend "options" there is a possibilty to choose a default folder for the Files.
The setting is: "administrator/components/com_paiddownloadsjx/files/"


But when i want to add a new file, then the selection list doesn't shows this default folder,
it shows the root folder of my server.

Then i changed the "default folder" into "myfiles/"

But it still won't show this folder, it still offers me to select a file from my server root folder.

How can i fix this?

It saves the file in the set "default" folder.
So this works, but when i want to add a file from the "select file" dropdown, then it shows me the root folder.

I want to sell very large files (700-800MB) , so i must upload them via FTP, i can't use the joomla-upload function. So it would be nice to select them in that dropdown list.


Anyway i found a way to get those files working.
1. i upload the file into my root-folder
2. i create the download with choosing the file from the "dropdown-list"
3. i move the file from the "root" to the "myfiles"-folder and it works.


PS: i use the latest fresh Joomla-Version
I also reinstalled the component and that bug is still there

Also have the same problem - just shows the files from the root folder... any solutions yet?
