Windows 10: Wildcards in Robocopy | Batch file very very basics

I have folders that contain files and subfolders. The files have a limited set of extensions.

What I seek to do is to robocopy /mir the files separately from the subfolders. I have been trying to review wildcard basics. I am not finding any ways to combine them that suits this goal.

I was thinking something like robocopy source directory files with *.txt (comma or &&) *.pdf…. *.svg….. destination /mir

If push comes to shove I can build a series of commands in a spreadsheet with one for each extension.

From what I have seen a batch file would be a cleaner method. Guess I need to go there sooner than later now.

I am vaguely recalling that I need some basic code that defines a variable, indexes the extensions, and runs a for next loop?

I found this discussion but quickly became lost in the details. Maybe I am in the wrong place?
Robocopy and For loops in batch file
ex.
for /f %%i in (c:\temp\comps.txt) do robocopy.exe c:\file_ini "\\%%i\c$\Program Files\usbdlm" usbdlm.ini

I get "for". Do not get "%%." "In" would be the source file? "do" is the execution command? The rest is somehow setting the destination? Does not this need some sort of "next" until or something like that.

Any guidance or background that speaks to the mission will be appreciated.

Thanks.

Same question now exists here

Repeat RoboCopy batch file in Windows 10 gives different results.

Running Windows 10 Pro 64 bit with standard supplied RoboCopy.

Having said that, I believe the same symptoms were exhibited on Windows 7 Ultimate 64bit (which was updated).

Basically I have a batch file which copies data from a 'non changing (by the OS)' drive to a backup drive.

If it has been run and completed so both drives are in sync, I can run the batch file again and it runs very quickly, BUT can sometimes give a different number of files in the drive. i.e. running it back to back gives different file count, even when the
2 drives are in sync.

Either this is related to caching of the drives, or RoboCopy not counting correctly when using multiple threads.

I would appreciate a definitive answer so that I can automatically test for files that are synced and provide a YES/NO to it having worked okay.

Robocopy switches

Hello -- one of the many switches that robocopy has is /xf -- to exclude file(s) that are to copy (not) copied --- the help (https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy) note that I can specify "wildcards
* and ? for the filename ---

So I specified the option

/xf foo.*

and I got a error that this option was invalid

Strictly speaking is the help noted that the filename, ie the part of the file identifier before the '.' can have the wildcard and not

the file extension/type?

Thanks in advance
