FAL introduced some great possibilities, but on an operational level, BE search for files is suboptimal.
In the global BE search finds both entries in sys_file and sys_file_metadata, since both have searchFields defined:
sys_file: 'searchFields' => 'name, type, mime_type, sha1' sys_file_metadata: 'searchFields' => 'file,title,description,alternative'
Finding a file (sys_file) is quite hard, since I have to know its file name. Searching for types, mime_types and the file's sha1 value do not seem to make too much sense to me. If I find it, I find an immutable file record, but there is no way to quickly get to the file itself (path is presented in the file TCA, but no link to file). It would be useful to have link here.
Likewise, finding metadata, does only show the metadata uid (some kind of title from title and/or filename would be helpful). There is no direct connection to the file other than the preview show in the form.
In file list, I can browse but not search/filter for files. This would be extremely useful, especially if you have several hundred images in a folder.

File search in Filelist is a big missing. It will be nice to have similar criteria like DAM (by name, by file type, by category, by status, etc). Hope it can be implemented for 6.2 LTS. It's a must-have priority for me, editors needs to find files quickly.

+1 for the search capabilities in the backend, at least a search for file name in the filelist module.
EXT:media comes with many other features one might not want to introduce into an existing installation. The UI is very different from the standard Typo3 file module, which would require extra user training and user permissions are apparently not respected. So this is not a real alternative.
(Also, an option to set the number of files listed on one page would be handy.)

As there seems not to happen a backport to 6.2 LTS, I leave a hint here:
EXT:falsearch for 6.2 LTS users seems to be a 'backport-like' solution, wich works also under typo3/ext/ (AKA 'global').
Both, falsearch-extension as well as the core-solution of v7.6 lack the feature searching for folder-names AFAICS.
