As a longtime user of ZTree (a paid program from Zedtek, a descendant of the old XTree file manager, inexpensive, and one that has provided me with free updates for several years at a time), I don’t think I’d have any need for this program. ZTree is a full-fledged file manager, offering either 1-Tree or dual pane views at your discretion, and must surely do a great deal more than 1Tree. I have found it to be superior and more readily accessible than others I have tried, such as Xyplorer or Total Commander.
