Some devices like the ASUS OPlay list files in disk order rather than alphabetical order. That makes it hard to find what you are looking for. Using this method, the disk order and the alpha order will match. Unfortunately, you have to copy all files from scratch when you add files...

Thank you! Just a little edit if you run this from another directory...

Code: Select all

for /f "delims=" %%a in ('dir c:\a\b\c /a-d /on /b') do (
   copy "c:\a\b\c\%%a" "c:\d\e\f"
)

One says the pipe character must be used if file names contain spaces:

for /f "delims=|".....

True?

False, (leave it as it was).

…and as I've said, it doesn't matter which order you copy those files, it will not effect the default directory sort order.

As filename can't contain "|"(pipe) character by default it does not matter if you use | as a delim or just leave "delims="

Thanks!

Here is an example of disk order listing:

@drgt, I fail to see the relevance.

You've shown a couple of images showing directory structures.
That has no bearing whatsoever on the order that files are copied into your specifically named folder.


If you were intercepting the files during their copy, for an intermediate action, I may understand the need to copy them in an order but not for a direct A to B copy process.

That is just an output of the DIR command, it has no bearing whatsoever on the directory order of files when copied. There should be no relationship between the viewed directory order and the order at which files were copied to the device..

Then why the device displays them in alpha order when copied in alpha order and not so when they are copied in the conventional way?

Compo,

Perhaps you not remember, but in the old MS-DOS command.com days the DIR command did not sorted the files in any order, so they always appear in the same order the files were copied to the disk. If you have any device that does not sort the files by name (like many cheap MP3 players, for example), then the files will be processed in the order they were copied to the disk, so in these cases such an order is important.

We have Networked attached storage that does this as well. Irritates the hell out of me on that server.

The file system at MFT or FAT is like a table of contents (TOC) in books or an archive file.
If the file stored on the hard disk is recorded on these repositories.
Your files are listed in this list.
When you duplicate your files, this list is read and treated one by one like the table of contents.
