[Samsung Galaxy Tab S8] drjoe1:
It seems weird you can download 4gb and larger files and not transfer them to other storage, huh?

So there are several possibilities I know of...

1) Install Paragon ExFat/NTFS and a compatible file browser (Total Commander, X-Plore File Manager). You need to pay for the needed plugins (NTFS, exFAT, or both). Then you can mount exFAT or NTFS formated storage devices and copy too/from. I find this is clunky and difficult to use, and I don't recall if I ever tried transferring large files with this method but it should work. THIS IS THE ONLY METHOD I KNOW TO DIRECTLY MOUNT NTFS STORAGE WITH WRITE PERMISSIONS TO YOUR TABLET. But I hate X-Plorer and Ttal Commander file browsers.

1A) Install Solid Explorer with the OTG Plugin. Both are pay, but well worth it.

I can mount exFat and NTFS formated USB-C memory directly to the tablet. exFat has read/write, NTFS is read-only. I think this is the best solution -- Solid Explorer is awesome, lets you have two memory units/folders side by side making file transfer easy. Best file explorer for Android I have found.

2) Install your storage device on your PC and turn on file sharing / full read-write access for devices on the local network. Using an Android file browser like Solid Explorer (my favorite), mount the dive as a LAN/SMB share. Your PC and WIFI need to be on the same network router (but the PC can be hard-wired). I just copied a 4.28gb file back and forth using this method. I don't think there were any additional plugins needed for this with Solid Explorer. Note this can take a long while -- I get transfer speeds over WIFI of 5-10 MB/s. I've seen reports of much higher rates, but never gotten it myself.

3) Attach the S8 to your PC with a USB-C cable and use your PC's file browser to move the large files back and forth. I just verified this too.

4) Probably you can share the file to /from your PC over Bluetooth -- I've never tried it. Even if it works probably much slower than WIFI.

5) You may be able to mount ExFat or NTFS storage devices directly to your router or mount external NAS devices on your home network, and use file transfer the same way as for PC shared drives. I did this with an older Asus router. I was able to download large files to USB storage devices mounted on the router and download torrents directly to the storage using a router based app. I could then use Solid Explorer to copy the files via WIFI to my tablet. But I couldn't copy large files back due to Asus limitations.

I commonly use methods 1A, 2 & 3 for exFat and NTFS file transfers to external storage. Unfortunately, neither 2 nor 3 is particularly fast. I used Paragon until Solid Explorer developed the OTG plugin.

Note that rumors say that Android 13 is almost supporting exFat / 4gb file transfers natively (but not sure about how Samsung will implement it). People report it for PIXEL.
