China DOS Union

Is there a hidden file in this folder? Which parameters need to be used? I tried it and it didn't work! I would like to ask if anyone knows? Thank you!

Try xxcopy.

New Features of XCOPY in DOS 7.0

Windows 95 provides users accustomed to DOS commands with the powerful MS-DOS 7.0. In addition to being compatible with lower versions of DOS, MS-DOS 7.0 enhances the functions of many internal and external commands and device drivers, making it more convenient to use.

MS-DOS 7.0 expands the functions of XCOPY, making it automatically call XCOPY32.EXE internally and becoming a real 32-bit application. And 11 new optional parameters are newly expanded, which are respectively:

/C: Even if disk read-write errors occur during the copying process, continue copying. Mainly applicable to copying files from a floppy disk (especially a problematic floppy disk) to a hard disk.

/I: When there is more than one specified source file and the target path (file) does not exist, assume that the target is a directory. If this option is not carried, the user determines whether the target is a file or a directory.

/Q: Copy without displaying the file name (fast copy).

/F: Display the complete source file name and target file name (including path) during copying.

/L: Simulate copying, only display all file names to be copied, but do not perform copying.

/H: Copy all files (including hidden files and system files) in the specified source file (directory).

/R: Automatically overwrite read-only files.

/T: Only copy subdirectories but not files, but do not include empty directories without files under the source directory. Otherwise, the /E option should be specified.

/U: Update existing files.

/K: When copying files, keep the target file attributes unchanged. When this option is not carried, the read-only attribute will be reset.

/N: Use the short file name (8.3 format, that is, 8 characters for the main file name and 3 characters for the extension) for copying, which is used to copy files to an operating system that does not support long file names (such as lower versions of DOS).

In fact, the most important thing when using DOS is to practice more. No one can remember all DOS commands. You can see their common usages by using HELP or /?. For example, XCOPY /?, which is a common method under DOS.

Makes a lot of sense!!!

Thank you, learned another trick

Under pure DOS, MS-DOS 6.22 XCOPY.EXE cannot copy hidden files and system files. You need to first change the hidden files and system files to be copied, such as AUTOEXEC.BAT and IO.sys, to non-hidden and non-system files before copying. And xcopy32 is for Windows and cannot work normally under pure DOS.
