The hard drive has dozens of g of space left, but copying a file with more than 4G hints:
Unable to replicate * * *: There is not enough free disk space.
Please delete some files to free up disk space and try again.
To remove old and unnecessary files on the disk to free up disk space, click Defrag.
Both disk defragmentation and disk bad track modifications do not resolve this issue. After the query that the original disk FAT32 does not support copying more than 4G files, need to convert to NTFS format.
Workaround :
1, "start" = = "Run" input "Convert j:/fs:ntfs/v" (the name of the disk partition that needs to be converted is J)
2. Open the command console with the file system type is FAT32. Enter the current volume label for Drive J: prompt.
3. Enter "Data" (my J-disk name is "data"), carriage return.
4. When finished, automatically close the command console.
Change the disk file system under Windows System (FAT32 to NTFS)
