I am using Microsoft Visual C++ on Windows and Qt Creator on Ubuntu. I can't change permissions on my flash drive (FAT32), even as root.
How can I change permissions on a FAT32 flash-drive?
vfat does not support Linux permissions. You can set permissions manually when you mount the device.
Unmount the flash drive from nautilus, but do not remove it.
sudo mkdir /media/flash
sudo mount /dev/sdb1 /media/flash -o dmask=000,fmask=111
You can possibly work around the issue if you use NTFS on the flash drive, and in that case mount it with the permissions option.
sudo mkdir /media/flash
sudo mount /dev/sdb1 /media/flash -o permissions
With the permissions option chown and chmod should work.
See man mount
Other options might be to use ext2 on the flash drive (smaller overhead) and the fs-driver on windows
