Netbeans 20 - problem with scanning external sources (cannot see them)

### Apache NetBeans version

Apache NetBeans 20

### What happened

Hello,
i reinstalled my PC and installed newest Netbeans 20. I have problem, that netbeans cannot see changes what i made out of netbeans. while i move files to projects, minify sources, convert sass/less to css, minify css throught netbean module netbeans dont see that and cannot autoupload files on FTP.

On older versions of netbeans everythink was OK. When i changed something externally, netbeans auto recognize change and auto upload file.

At project settings i have checked "auto upload on save" - its working fine when im doing changes in netbeans.

At netbeans settings i have in Tools -> options -> Miscellaneous -> Files checked "Enable auto scanning sources".

Does anyone have same problem?

Anyone have any ideas please?

Thank you all! Dominik

No

Reproduce the issue by moving a file into a PHP project externally on Windows, then check the project view with “Enable auto scanning sources” enabled. Investigate the external-source scanning and “auto upload on save” entry points; done means externally changed or added files appear without manual synchronization and are uploaded as expected.
