2004, August - Release 2.0-0 with name VTfm.

• developed on DEC C v6.0;
• redesigned and reduced source code;
• supports VT-terminal modes with more than 24´80 rows/columns;
• uses TPU$TPU routine for view and edit;
• works on VAX, Alpha and IA64 with OpenVMS.

Currently known restrictions:

• does not accept node specification in GotoDir, Edit, Copy and RenMov operations (use VTfm command line instead in this cases);
• does not translate disk device logicals in RenMov operation, so if, for example, logicals XXX: and YYY: point to the SAME physical disk device VTfm RenMov files via copy;
• does not Copy directory files with their content (make destination directory first and then Copy source directory content);
• does not RenMov directory files with their content to ANOTHER logical or physical disk device (make destination directory first  and then RenMov source directory content);
• does not open any archive files (use correspondent utility in VTfm command line).

2004, October - Release 2.2-6.

• Copy, RenMov and Delete DIRECTORY TREES;
• supports LOGICALs when GotoDir, Copy or RenMov (SYS$LOGIN, SYS$MANAGER, SYS$COMMON, SYS$COMMON:[SYSMGR] etc.);
• recognizes the same disk device with DIFFERENT logical names when RenMov, so if, for example, logicals XXX: and YYY: point to the SAME physical disk VTfm RenMov files WITHOUT copy;
• works on VAX, Alpha and IA64 with OpenVMS.
