Found the following dos copy programs until now that supports excluding files.
- icopy121
Shareware version. Have to check what kind of limitations it has.
- pcopy93d
Shareware version. This version has a 30 day trial period and a nag screen for registering.
- qkopy341 (quikcopy)
Evaluation copy. This version has a 14 day trial period.
I do not know if the authors are still selling the software and if possible a registered version is available somewhere. Do not want to use some illegal copy without the authors permission.
i could also use the date parameter if a copy program has it. I checked xcopy but it only has an after date function so not before. If a program has a younger date function I can copy all files except dosbox.conf because it has a creation date of 2026.
Update.
Tested icopy121 and it worked perfect. It is an donation version so has no limitations. Copied all files with the parameter /EXCLUDE:DOSBOX~1.CON so it keeps it original dosbox.conf name.
Finally found multiple versions of XXCOPY16 that has 160 parameters and also a move function. Perfect.
