I can add SOME files and save but I cannot add ALL desired files. Â The original ISO size is 2.337 gb (52% capacity). Â The added files bring the total to 3.766 gb - well below the max. Â When I attempt to "save as" it immediately hangs. Â On closing it says "This program is not responding". Â I've tried on WinXP and Win7 computers using the latest UltraISO version. No luck.
I deleted some of the file on the original ISO and then tried adding the other files. Â This time it worked flawlessly. Â In other words, the additional files do not have an inherent problem.
