File doesn't show up in TYPO3 Fileadmin

is TYPO3 doing some indexing of the filesystem into database? We try to add a video to our page here, but video isn't selecable from the file window altough its put into the right directory. The Fileadmin says "9 records found" in the folder and is displaying only 7 Files, because someone might have deleted two of the files out of the folder. But the new video file we've put there won't be displayed, too.

Is the开发者_开发技巧re any way to manually start TYPO3s file indexer?

I don't think TYPO3 does any indexing of the files; it just reads the list of the files straight off the filesystem. So there's no file indexer to start.

My suggestion for your problem would be to check the permissions on the file you uploaded and make sure it's readable by whatever user the Web server is running as ('apache', 'www-data', etc). If it isn't readable by the Web server it won't show up in the fileadmin area.

Okay guys, I feel stupid right now - altough I can't really explain the behavior... What happened seemes to be some strange caching failure.

If you click on the "choose file" button it shows the window as seen in the screenshot above, displaying the last used folder. But: this view is somehow cached. If you select the same folder again from the file tree from the left, the view is updated and the missing files are shown -.-
