Why files are not copied?

The thing is in different file systems (FS), which Windows and macOS use by default. On modern Windows computers, FS is called NTFS (on old and Fat32), on Mac. Hfs.

In those distant times when FAT32 was introduced, Apple was less uncompromising than today. and therefore made support for this FS for the Mac. If the flash drive is formatted in FAT32, any computer on OS X (macOS) will be able to read and write files to it. There is, however, one unpleasant exception. All in the same distant days when FAT32 was introduced, no one could have thought that files larger than 4 GB would be written to an external drive. The limitation is still relevant today, so you will not see a high-quality movie or any other file larger than 4 "gigs" on a flash drive with the FAT32 file system.


A relatively new format proposed by Microsoft. A flash drive formatted in this format will work perfectly. Which is especially pleasing, the FAT32 file size limit has been removed. Let’s say more. this option is optimal if the flash drive often "travels" between computers on Windows and Mac.

Formatting a flash drive to ExFAT format (or any of the above) on a Mac is very simple:

1. Open the program on your Mac Disk utility.
2. In the menu on the left, select the desired flash drive.
3. Select Erase (button in the top menu).
4. In the drop-down menu to the right of the inscription Format select file system Exfat. Optionally, you can specify the name of the disk in the field Name.
5. Press button Erase at the bottom of the window.


If you are a Windows user, an inexperienced Mac owner can bring you a USB flash drive formatted in native Mac OS HFS (Mac OS Extended) format. As already noted, it is not compatible with the usual Windows file systems. You can work with such a disk. but for this you need a special intermediary program called Macdrive. The purpose and principle of operation is the same as that of NTFS for Mac, but the trial is less (5 days), and the price is higher. 49.99.
