Why do the Same Files Take up More Space on my SD Card?

Hi, I have a strange issue. I use Windows 7, which is why I posted here, even though it's not directly related to the operating system.

 

I have an LG G4 with a 200GB micro SD card that I use to hold all my music. I have been trying to use MediaMonkey to sync to my phone. I have all my music files on an external hard drive, they are all in a folder called "Music Backup." Media Monkey tells me that my SD card is 183GB formatted, and the folder of music is 179GB, but each time I try to sync, the SD card runs out of space.

 

I figured it was a MediaMonkey issue and decided to format the SD card and drag and drop the music folder. The same thing happened so I checked the folder properties.

 

On my external drive, it says Size: 178GB, Size on Disk: 179GB

On my micro SD card, it says Size: 178GB, Size on Disk: 182GB

 

Exact same folder. What the heck is going on?

Why don't you just Drag'n'Drop?

 

and does one of the folders have the album art and one does not?

 

also you can have 2 200GB drives and they will be different sizes (in megabytes) eg, 200GB = 200000MB it's not exact so one could be slightly smaller than the other, which is why you are seeing that roughly 2+ GB difference.

Drag and Drop does not synchronize, it copies. OP is trying to sync.

 

 

OP the files are different sizes because they are on a different disks. Each disk format type has a different way of allocating space.

I believe that Gorbulan may be correct...the disk format on your hard drive is NTFS while the format of the SD card and external hard drives is probably FAT.

Got it, good info. Can I format my SD card differently so there isn't so much wasted allocation space? If I format in NTFS will it still work on an android phone?

Thanks, I actually just realized that there is an option to set the allocation size when I format. It is set to 256kb. That is definitely where all the wasted space is. I will set it to 16kb and that should clear up the issue.
