Windows 10: How do I accomplish renaming bulky indexed files to smaller number?

How do I accomplish renaming bulky indexed files to its smaller index number, with any kind of tools ?
That is to rename

1.c -> 0.c
2.c -> 1.c
...
7.c -> 6.c
8.c -> 7.c
9.c -> 8.c
...
...
(in large numbers of files.) Thank so much in advance

Give name and merge people in Windows 10 Photos (Falls Creator update)

I have the same issue. Just loaded 47,000 photos. Windows indexed them into 1,500 people, many of which are the same individuals at different ages or in different contume. The indexing function is excellent. Now I'd like to merge people into a smaller
and more manageable number of unique individuals. The logic of this functionality does not seem complex. Yet, I cannot find a way to accomplish the task with the current software. Does Microsoft intend to add this functionality in a future release? When
might it be available?

I tried your Method 1 to fix it which said changes have been made to my computer & to try & update again which failed.. again & the same message above came up again. My laptop is secure as I run Norton 360, so what should I do next to try & fix this problem?
My laptop is a Toshiba satellite L650.

You could create a batchfile e.g. rennum.bat

Using following from admin command prompt



Dir /b /s > dir.txt

Then create a batch file rennum.bat with

rename

Repeated many times.

Then use notepad++ which supports block column copy to paste all of contents of dir.txt after the rename commands. Then paste same data shifted up one line after the first block.

I'd solve and answer mine. on Windows cmd.exe console:

cmd /v /k
for /f %x in ('dir /b ??.c') do (set/a t=%~nx-1 &ren %x !t!.c)



rename to greater number; dir in reversed and +1, i.e. use:


dir /b /o-n
t =%~nx-1


Much better is to get TCC/LE more improved and sensible cmd.exe duplicate

You can also do this in PowerShell:

Code: foreach ($file in Get-ChildItem -Filter *.c -Recurse) { if ($file.fullname -match '\\([0-9]+?)\.c') { Rename-Item $file.fullname ([string]($matches[1]-1)+'.c') } }[/quote]
