Of .zip and .7z
« on: 06 December 2017, 14:58 »

Cleaning up my mame roms after a bit of a break. Grab the latest clrmamepro as usual and begin to bring mame up to the latest version.  While updating, I started getting "Set exists in multiple rompaths..."  Digging deeper i have a .7z version of the rom and a .zip version.  I guess over time, i hadnt really paid attentin and my roms have both .zip and .7z files (769 files are .zip and 33,000+ are .7z, just to give you an idea of the ratio).  Looks like this happens when i do a rebuild with a .7z file on a current mame .zip in my  roms. Is there a way to make sure that it leaves only one version  on a rebuild therefore avoiding the multiple sets?  Or do i need to take care of getting all the roms zip or 7z completely.  If that is the case, which is preferred and is there a way to convert to one format or the other all at once (taking time im sure). Thanks for any help you can provide!!

The scanner, when fixing files or adding files via fix-missing, checks a) does the set exist, if yes, take its archive mode, b) if the set does not exist, take the prefered one (which is determined on startup by a simple count of all available files)..if no files are available it's zip.

When rebuilding YOU define the archive mode and newly created files use that one. Actually I have to double check what happens when only a file is added to an existing archive....but the case with new files can already mix archive types since no, currently there is no rebuilder routine which only keeps one archive type alive.
