Windows 10: Invalid File Name

Hi all,
Sorry for my poor english.

I have a SDHC 32GB card and I formated it to exFAT, because I need it for a file that is bigger than 4GB.
Everything looks and run good, expect 2 files (my own) that I can´t open and read it, the App says "Invalid FIle Name".
I can see it´s Properties with File Explorer, no problem there.
I did re-format to it´s Original FAT32 format and I can read those files normally.
To format to exFAT I used Windows, to format back to FAT32 I used SDFormater from SD-Org.
I had a 64GB SDXC card, I formated it Windows and my Android did not recognise it.
I spent 8h around this problem till I found that it was the SD Card format problem.
Has it to do with Windows Format utility ?

:)

 

Invalid file name

What is the filename of the file you are right clicking on?

 

Invalid file name

I'm trying to make a file a picture since it's a video I made using the game bar, but when I try to click "add this folder to pictures" it tells me Invalid File Name.

 

NTFS works good for me to copying files bigger than 4GB.

No third party program is needed. Just Right Click > Format and set the file system to NTFS.

Hope it will work.

 

Hi Arc,
Thank you very much, NTFS is working.

I did some further research on the issue, using a SDXC 64GB, native format, on other PC and the problem still there.
I found out that the problem is related to the Folder Name, it can not have Spaces on the name.
It can be as long as I wish, but if there one Space on the name, there coming the error "Invalid File Name".
So, there is a bug, either is my App to old and is not totally compatible with exFAT or there is a problem with exFAT itself.
Thank you.
