I am MS window user , currently using window 11, also I am developer in a organization, when I am trying to copy multiple file or folders from one location to another location if the files size are larger it is taking much time and you dont have control there to stop copping the file/folder which is larger in size on the fly. We can build this in such a way that we should have full controlled in where we can choose what to cancel and what to go "On the Fly" , this will help user to have control to cancel the file which is taking more time, will do it later. But currently if you cancel it will cancel all and user has to re-do.

XCOPY with unbuffered I/O is maybe a better choice, but it actually depends more on partition alignment (sector size,) and also your choice of file systems. While NTFS may have the best integrity due to it being a journaling file system, it might not be as fast as exFAT for removable media. It's smarter to look at the tradeoffs, long-term data integrity vs speed, etc, but also partition / sector alignment, as it relates to 512e / Advanced Format drives, and the typical partition that is aligned in an array with other drives that have a sector size of about 4KB.

XCOPY source [destination] [/A | /M] [/D[:date]] [/P] [/S [/E]] [/V] [/W] [/C] [/I] [/Q] [/F] [/L] [/G] [/H] [/R] [/T] [/U] [/K] [/N] [/O] [/X] [/Y] [/-Y] [/Z] [/B] [/J] [/EXCLUDE:file1[+file2][+file3]...] [/COMPRESS] source Specifies the file(s) to copy. destination Specifies the location and/or name of new files. /A Copies only files with the archive attribute set, doesn't change the attribute. /M Copies only files with the archive attribute set, turns off the archive attribute. /D:m-d-y Copies files changed on or after the specified date. If no date is given, copies only those files whose source time is newer than the destination time. /EXCLUDE:file1[+file2][+file3]... Specifies a list of files containing strings. Each string should be in a separate line in the files. When any of the strings match any part of the absolute path of the file to be copied, that file will be excluded from being copied. For example, specifying a string like \obj\ or .obj will exclude all files underneath the directory obj or all files with the .obj extension respectively. /P Prompts you before creating each destination file. /S Copies directories and subdirectories except empty ones. /E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T. /V Verifies the size of each new file. /W Prompts you to press a key before copying. /C Continues copying even if errors occur. /I If destination does not exist and copying more than one file, assumes that destination must be a directory. /Q Does not display file names while copying. /F Displays full source and destination file names while copying. /L Displays files that would be copied. /G Allows the copying of encrypted files to destination that does not support encryption. /H Copies hidden and system files also. /R Overwrites read-only files. /T Creates directory structure, but does not copy files. Does not include empty directories or subdirectories. /T /E includes empty directories and subdirectories. /U Copies only files that already exist in destination. /K Copies attributes. Normal Xcopy will reset read-only attributes. /N Copies using the generated short names. /O Copies file ownership and ACL information. /X Copies file audit settings (implies /O). /Y Suppresses prompting to confirm you want to overwrite an existing destination file. /-Y Causes prompting to confirm you want to overwrite an existing destination file. /Z Copies networked files in restartable mode. /B Copies the Symbolic Link itself versus the target of the link. /J Copies using unbuffered I/O. Recommended for very large files. /COMPRESS Request network compression during file transfer where applicable. The switch /Y may be preset in the COPYCMD environment variable. This may be overridden with /-Y on the command line. C:\Users\<username>\Desktop>
