Today morning - in Dream-explorer plugin I removed whole "movie" directory (placed on usb hdd mounted as /hdd).
Exist some utilities for e2 box (mips32el, but I can plug it to arm too) recovery files in this directory or for recovery this whole directory with all subdirs too ?

from ext2 to ext3 to ext4 it becomes progressively harder to recover files after deletion.
There is a tool though that tries to find and stitch together media files. I'm not too sure it also works for transport streams though. It's called "testdisk" and it has a program called "photorec" with it.
I don't think it's in our OE though.

That is the risk of a plugin like "Dream-explorer"... with normal E2 the files are moved to .Trash...

No, my target was remove picons (which I installed due somebody 
) ... I do not know, why I used movie - too early in the morning for me.

It has no sence with photorec ... thousands and thousands .ts and .mpg files with 12kB-24kB...

I prefer for such job to use the console (putty)... you can do an extra check with ls before deleting... With the UI browser an accident does happen too easily.

I see, how I starting putty from bed
It was overwhelming. Instead delete on 'movie' I press it one directory botton - on 'movie'. And with confirmation ! Well, the box has 1TB free space again.
there are more recovery tools, give it a try
Thx, but all this softs are more/less for corrupted filesystem etc. I have not corrupted filesystem, I used standard remove directory... and it seems, it is big problem under ext3/4.

You could look at "photorec" in combination with "foremost" both are native in the Kali Linux distro

...and there are solutions when you move the USB over to Windows https://www.easeus.c...-ext3-drive.htm

Bottom line is that the more advanced a file system becomes, the less remains of a deleted file. Compare to FAT where only one bit is toggled in the FAT entry so very easy to undelete. With ext2 is still was more less possible, ext3 less and with ext4 it's simply impossible.
It would be nice if the file system itself would have a feature to support salvaging of deleted files (like Novell did), instead of relying on design flaws (FAT...). So it would not touch any data or metadata used by now deleted files until there are no more really free block and then start recycling the ones deleted longest ago.
Or use a NAS that does support snapshot backups AFAIK BTRFS also supports something like that.
