Copying Files Fails With "Parameter Is Incorrect"
When copying, moving, or synchronizing files, Beyond Compare gives the error message "The parameter is incorrect".
This error is usually displayed when copying a file larger than 4 GB in size to a target drive that uses the Fat32 file system. The Fat32 file system's maximum supported file size is 4 GB. Files larger than this will fail to copy with the "parameter is incorrect" error.
A solution is to reformat the drive using the NTFS file system, which supports larger file sizes. Note that reformatting will remove all data from the drive. To reformat a drive, right click on it in Windows Explorer and select "Format". In the Format dialog, make sure NTFS is selected as the file system type.
