Thanx mta 4 your Reply & your Help!
it happened 1st w/ Zorin Education Lite Linux which is 2.5 GB & Lubuntu 19.04 Desktop X64 Linux which is 1.5 GB & w/ Every Other iso, about a Dozen so far down to 600 Mb, ( getting progressively smaller, but I've still got another 60 isos 2 add, rite down to 9 Mb Corepup Linux ( altho it's occurred 2 me that maybe I should have started from small 9 Mb & Finished w/ 2.5 GB iso ) because as time goes by I'll be Updating them & of course the isos get Larger & I'll have 2 Defraggler them again )
it's a 32 GB USB Flash Dr. ( Only 6 isos aRe bigger than could fit on a CD ie. 860 Mb - 2.5 GB Zorin previously stated, wood otherwize Need 2 be Burned 2 a DVD ), But the Vast Majority aRe 200 Mb - 300 Mb Puppy Linux isos, which I've yet 2 Do because at the moment I'm in the 600 Mb iso Zone. Frustratingly I'm having 2 Defrag the USB Flash Dr after adding each iso! As I said earlier there's a Total of 72 isos!
