Thank you for the update!

Regarding the „-g“ option for CLI — that’s unix CLI style. For AmigaDOS, one should parse arguments using ReadArgs(). In this case, the template would be e.g. :

G=GUI/S

And would be called with

Mnemosyne gui

or just

Mnemosyne g

Check out Autodocs for dos/ReadArgs()

If you dive into a subdirectory and return to the root dir via back-button, the whole volume will be scanned again. Maybe (optionally) cache the results to speed things up? :-)

Some values won't get rounded

Implement opening of listed files via double click, so one could check the contents of the bloated discoveries. Using DefIcons of course. :)

Same functionality is present in OS3.2's "Find".

Scans can take a long time - it'd nice to be able to abort them.

Mnemosyne will write into non-allocated memory when entering subdirs/pressing back-button.

Mungwall log (one hit per doubleclick in listview/back-button press):

I bet you've got something like this on your list somewhere. ;-)

It's from SequoiaView. Also check out WinDirStat on Windows or DiskInventoryX on Mac.

For our old machines, a nice 2D-view with rectangles in colours representing file types would suffice.

Scanning dirs is fast on "high end" classic machines, but could potentially take a long time on slower ones.

Suggestion: Add an activity animation or (progress) bar during scan.
