I'm software developer and I'm big fan of Total Commander for more than 10 years.
Unfortunately (or fortunately

Because of that, I'm looking for an alternative.
Two days ago, I installed Free Commander XE (601), I have checked almost all its functionality and I'm thrilled!

Almost in all segments Free Commander is better than Total Commander. I liked very much internal viewer, search options like "append to found items", the concept of the file filters and many others. Also, FC is much more customizable than TC. You did excellent job!
Some of the features that I use more often are folder synchronization and compare files. I saw that you are planned the implementation of folder synchronization and I'm curious when it will be finished?
I also tested WinMerge, but in my opinion Total Commander compares files by content much better (not on the word level, but on the character level).
Do you plan to integrate TC like files comparator?
Thank you again for the most powerful file manager on the world!
