Total commander is a great successor I think. Once you get used to 2-pane logic, the efficiency boost with anything file-related is really huge. It is fast and has so many features - tabbed panes, quick recursive file content search, very nice comparison of 2 files, folders synchronization, built-in navigation in archives (I often edit files directly in packages, it recompresses them automatically) and archives within archives, great network/FTP browser and many more... it really packs few tens of great tools into one neat package.

One of many detractors from Linux in the past from me - whenever I tried any equivalent there, it was very slow, featureless, crashing etc. I hope these days the situation is better.

Whenever I look at any other colleague, who use that primitive File explorer or equivalent, how clunky and slow work it is, its sad that people don't do this one-time effort to transition to the tool which is so vastly better.
