Memory card problem, need answer please.

[Gwynbleidd]

So guys, today I bought this memory card Transcend 64GB MicroSDXC Class10 UHS-1 Memory Card with Adapter 45 MB/s (TS64GUSDU1E)
Looks like I can't post links so I just wrote name. So problem is this: When I transfer some app/game from my phone storage to SD storage that app/game suddenly becomes much larger than before. For example if I download 5mb app on memory card storage it is not going to be 5mb size but 120mb size, when I transfer it back to phone storage it's 5mb again. I don't know what is going on. I just transferred 2.5gb size of apps to SD storage and it now it takes 6.7gb space wtf. Simple 5mb app becomes 100+mb app... On windows store it says that this game
"Age of Empires?: Castle Siege" Approximate size
190.41 MB - 814.81 MB
But on my memory card it takes 2.11GB and I never even started that game. Please help me.
I have Nokia Lumia 735

I think thats normal.
I have 630 DS and 640 XL.
I've noticed this on both my devices.

However I don't know about AOE taking up 2.11GB

I did a move right now and checked ...
there is a difference

I just checked mine, moved Stpwatch Timer which has 21.8mb to my SD and now it takes 22.8mb, not that huge difference. Guess it needs some path to add so it could be used while on SD, i don't know, i'm just talking nonsense :d

Even small app like this got 10 times bigger lol



And here is AoE

Mozda je do kartice, promjena velicine aplikacija kod mene je vrlo mala.

Maybe you have a malfunctioning SD card, since the size changes on mine are insignificant.

Here Maps
Phone: 68,87 Memory card: 246,38
Skype
Phone: 59,65 Memory card: 202,25
Here Drive+
Phone: 60,78 Memory card: 178,75

BTW only apps and games get extra size while videos, music, pictures remain same,

Check the sector size used when formatting the SD card.

Can you please explain me how to do that? I am sorry, but English is not my main language so I don't understand how to do that.

Insert your SD card into your PC, copy everything off, format it and in the format dialogue you can specify sector size, probably best set to default, but you can experiment. SD cards pre formatted can have different sector sizes to the MS default OOB. You can format at Fat32 or ExFat (ExFat only for 64gig+ cards). Then copy everything back to the card.
