All was well and I haven't done anything, to my knowledge, that could've changed it.
However, when I unpack zip archives, the directory structure is not being maintained.
All the files are being extracted, but the files in subdirectories are all being put it the root.
I've configured TC so that I can unpack using "unzip", using a button. But, when I delve into the archive and want unpack from the lister, it's doing the weird thing, described above.

Please, can someone put me out of my misery?
