Total Commander 7.55a is a lot slower than Windows Explorer when copying files (most visible with big files) to an external USB drive (18MB/s versus 28MB/s).
I've already tried:
- disabling anti-virus
- disabling plugins
What can I do to speed it up?
I think you have enabled the Total Commander copy style. That copies each file one-by-one, this is a very usefull feature if some files allready exist. Windows (at least up to XP) only let you overwrite or cancel the whole copy at once. TC allows you to skip/overwrite on a per-file basis.
You can disable this copy style on the Options page
