Thank you for clearing up my doubts.

I have tested it without disk spanning, means only 1 file (~1,3GB) with pz+sr+lz and extraction was ok with 2050 and even 2039 should'nt have any problems with it as long as disk spanning is not set.

Yep, but the main cause of creating MMC 2.0 is splitting, which works better in this program.

Ok, waiting for this.

Just needs MASK support, then i'm happy :D

You can try with the simple script included with MMC to see how splitting works here and detect bugs. About masks, well then I will create a separate exe for masked data compression 2.5(or else?)

add rz.exe and mcm.exe

As I don't use masks that much, nor rz and mcm, so I am thinking of releasing a version for devs like Simorq. Will contain a ini in which you can edit the methods and the names of the checkboxes. As soon as you add the two files(MMC.exe + Settings.ini), it's ready for use. Remember this program is created using inno setup.

This would be even better :)

Create iso not work

You sure? :/ Because when I tested it worked.

Make sure you selected icon, exe and gave a disklabel

Only works for the first disk.
Of course, this is a problem with cls-diskspan.dll.
ISO file for making better use of ImgBurn.

I don't know why you are getting errors, but it worked for me. Anyways, I will try to fix it when I have time. Also, creating this s**ts with inno is waste of time. Probably will make a more advanced one like UltraArc UI by delphi.

MMC - Dev Edition
 

For editors like simorq ;)
