Started with a twin-panel file manager called "du" on a Kaypro 2 with C/PM in 1982.
Found Norton Commander about 1984 on a 286 PC along with TurboPascal_1.0/3.0 about 1984.
A real speed demon.

And TP3 was even better --complete development environment on
a floppy disk with room for lot of source.
Then came upon Window's Commander which morphed into Total Commander.
Began using Win(Tot)Cmd in about 1992. Also CMFiler, a DOS twin-panel file manager,
for those moments when Win95 was incapacitated.
By 1997 when I began learning about Linux, I started looking for a replacement for TC.
In email conversations with Christian Ghisler, he said he was not interested
in building a Linux version of TC. Someone suggested Krusader for Kde and that helped me
make the change to dual-booting Linux in 2000. Still learning.
In Jan 2001, switched completely to Linux. Had to learn how to do all the things that
were so simple in Win98 and DOS --FTP, file recovery, file management, etc.
I really like Krusader. Even helped document Krusader. It is patterned after Total
Commander and was one of the first things I installed on a new Linux install of anything.
Began my experience on Linux with Mandrake7.2-(Kde), Kanotix, sidux(Kde->Xfce),
Debian testing, LinuxMint, PepperMint, & SalineOS(Xfce4) which is what I use today
on several machines.
Having left Kde around 4.0, I mainly used Xfce4; but still, installed Krusader
with all it's Kde libraries at each new install. But a while back I read about SpaceFM,
which sounded nice and was not Kde4 bound. Alas, it would not install in SalineOS
(Debian stable), but I saw a note about Double Commander and took a look.
There was not really a Debian version, but I tried and installed the Lucid version into my
SalineOS (Debian Stable) and to my surprise, it was even better than I had hoped. Not only
was it like running Total Commander again, which I still use on my boss's WinXP laptop,
I could get rid of all the overweight KDE libs.
Only been using it a couple of days, but I love the fact that it is written in FreePascal.
Debian stable only offers fpc-2.4.0-2. Will have to look into that.
Thanks, for your efforts. They are appreciated.
Regards,
Richard.
