Bug description
In Pharo 13, when openning the "File Browser", the Pharo image freezes each time for long minutes.
context : we use multiple disks with a lot of directories on it...

Version information:

• OS: Windows 11
• Pharo Version 13.1.0

Workaround
The problem seems to be linked to the number of elements of the upper left part "Directories".
The good solutions should be to expand the tree when requested, not when openning the panel.
For my team i manually commented in StDirectoryTreePresenter>>initializePresenters the line

children: [ :aClass | aClass subdirectories ];

it becomes :

"children: [ :aClass | aClass subdirectories ];"

another solution should be to add a setting to disable the StDirectoryTreePresenter ...
the best should be to build children only when openning the tree... but i don't know how to do it in spec...

Cheers
Eric.
