In Windows, file names containing special characters are stored in a special format for compatibility with older systems that understand only format FAT and FAT16 where file names with the size of 8.3 - 8 characters for the file name + 3-character extension.
For this in table FAT32 uses a standard FAT table for short names (ie names in 8.3 format) with a special format recording system indicating that the file also has a long name.
Thus, working with files in a terminal emulator Windows, you can refer to files using the name as long and short. Long name if it contains a space must be enclosed in double quotes.
