    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 canīt open and read it, the App says "Invalid FIle Name".
    I can see itīs Properties with File Explorer, no problem there.
    I did re-format to itīs 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 ?

    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.
    Click image for larger version.

    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.
