It works, but after i transfered a 2gb file it was fine. But my previous files on the sd card (larger than 4gb) are disappeared and the memory is still used by them.

Is your micro sd card formatted in FAT32? To store larger files than 4 GB your micro sd card must be formatted in exFAT.

Its exFat and as i said i have stored files that are larger than 4g on it before i used this tool, and these files are disappeared after i have copied a file with this tool.

I would try joining the files after you're done transfering. Something like this, in a command line:

copy /b game.xc0 + game.xc1 + game.xc2 game.xci

Not 100% sure if it would work, and I can't test myself since I'm using fat32, but worth a shot. (maybe I'll try tomorrow with smaller files just for the heck of it. Not right now, as I'm hitting the bed. Stay tuned.)

Edit:
Tested and it works, but you first have to assign a drive letter to the Switch. An easy way to do it is to use this program. For me, the latest version 3.1 didn't work (on Windows 7 64-bit), but the legacy version 2.10 works very well. Trial version, but it does the job for what you need to do.

Once you've assigned a drive letter, open it normally in Windows explorer, and open a command prompt there (Shift + Right-click > Open command window here). Then join the files as I described.

To split the big ass file in the first place, you can use hjsplit, or xci-cutter (for xci files). I know it's a drag to use all these steps, but it's still a viable solution if you want to transfer bigger than 4GB files.

Files larger than 4 GiB shouldn't enumerate at all, actually, but I've obviously overlooked something.

Your "disappearing" files are likely caused by them being re-queried through a method with proper checks. The files are not (or should not be) deleted, unless you explicitly delete them; they simply become inaccessible through this interface.

Its an 128gb card and 29gb are on a hidden partition (emuNAND).
An my games that are stored in the XCI folder before i mount the card with the tool are invisible now.
Each file that are invisible have a size over 4gb.



As you said, the files become inaccessable, this tool triggered something after mounting the sd card.
Is there a way to make them visible again?!

Files bigger than 4GB? Are these XCI?
It would be cool if these FAT32 limitations could be solved. That would make the homebrew near complete.
I've been using it intensively and can say I ran into zero issue.

Yeah I've been using it quite a bit the last few days. The first time I used it files were going really slow for some reason, but every other time they've transferred at a good enough speed.

I was using exFAT before, and to be honest, I never had a problem, but after reading about a lot of users having issues with corruption using homebrew, I decided to not take any chances and converted to FAT32. Yes, you got to split the big files (XCI or NSP) but since they're well supported by SX OS, why not? Just takes a little more time. And with this great app we're talking about here, it's super easy and fast to transfer to your microSD without ever having to turn off the Switch and remove it (then you'd have to reboot your CFW). Call me lazy, but I'm calling it convenience and efficiency. This app should have made front-page news. It's that good! :D It should convince people who are on the fence, trying to decide if FAT32 would be better.

    although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
  • SylverReZ @ SylverReZ:
    @BakerMan, I think you're talking about the recovery mode that the SaveMii used, and also was to restore softbricked systems.
  • SylverReZ @ SylverReZ:
    If your NAND was hardbricked, then just buy another Wii. Or go with the dirty NAND flasher method.
  • BakerMan @ BakerMan:
    and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
  • Xdqwerty @ Xdqwerty:

  • SylverReZ @ SylverReZ:
    @BakerMan, Oh yeah, that was a thing too. Dolphin does support Wiimmfi.
  • BakerMan @ BakerMan:
    yeah you just need to put your NAND backup with wiimmfi on it
  • BakerMan @ BakerMan:
    ngl i feel like if a bunch of my friends have wiis and know how to get wiimmfi and back up their NAND, then we could do a PMEX Remix tournament
