I'm working on a backup application (something like dropbox, only for different market and different purpose), For this, I need to reliably track changes made to file system.
Because of the way Windows works (see my other question about it here), the only reliable way to track changes on the file system is by getting modification date directly from NTFS disks via the change journal.
I was able to do this, it works wonder, and even support/handle massive changes (ie. copying large folders), but this only works on NTFS disks.
My application target Windows XP+, I know NTFS has been the default file system since XP. I highly suspect most use NTFS, but I still wonder if there's a reliable recent statistic about usage of FAT32.
In other words, I'd like to know if it's worth bothering to support FAT32 disks
