Recover deleted files after removed it from trash, but before use GC

Is there someway to recover files after they are removed form trash, but the blocks still exist, because we don´t use GC, thanks.

Yes it’s possible , you have to use the tool FSCK.

but i review the manual and it don´t say anything about it, it just say about recover corrupted library, but it´s not the case

I think I said an error I made a try by deleting a file and then using the following command:
cd seafile-server-latest
./ [–repair|-r] [–export|-E export_path] [repo_id_1 [repo_id_2 …]]
and the result is not good , I can not find my file delete
