I'm trying to backup 4.5GB file to my SdCard. But my SdCard file system is FAT32, so that I cannot backup my file. (FAT32 doesn't support to save 4GB size file)

File system limit - https://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits

So I need to check my SdCard file system is FAT32 or not. If my SdCard doesn't support to save large file then I need to save it by splitting.

Or if there is another way to check to save the large file?

Could you give me a help?

`my SdCard file system is FAT32` already provides an answer. – Phantômaxx Feb 17 '16 at 09:12
@HrundiV.Bakshi yes, but i want to check other general cases. and i'll modify my question. – larsien Feb 17 '16 at 09:15
`i want to check other general cases` The filesystem never changes. – Phantômaxx Feb 17 '16 at 09:18

Java doesn't provide this facility in its native APIs. I suspect you'll have a hard time figuring this out in code. – Doug Stevenson Feb 17 '16 at 09:19
@HrundiV.Bakshi I mean a case of using exFAT or FAT32 SdCard. Some SdCard's file system is FAT32 but others are exFAT. – larsien Feb 17 '16 at 09:21

And some are ext4. So, your question should be: `How do I check my SD Card file system type?` – Phantômaxx Feb 17 '16 at 09:22
@DougStevenson I tried to investigate "mount" file but I couldn't get the information which I need. I think I need to study more... – larsien Feb 17 '16 at 09:23
