How To Change Folder Names From Uppercase To Lowercase In Windows

Remove From My Forums

create/rename binder majuscule

Question
If i create a folder in Powershell with:
```
New-Detail D:\TEST -type directory
```
The name is all lowercase.

How tin can i create a binder that the name is similar i wrote information technology?
And how tin can i rename a folder "exam" to "Test" or "TEST"?

I searched Google for an hr but its all about bulk renaming.

All replies

What you lot posted to a higher place creates the directory as TEST on my motorcar. To rename Test to test or Test, you lot showtime have to proper name it something different, then rename it again to what yous want
```
Rename-Detail -Path D:\TEST -NewName Test1 Rename-Item -Path D:\Test1 -NewName Test
```

Maybe simply a presentation error?
I do this from my workstation via remote desktop on my Hyper-V 2016 server.

Name says "VMs"
But "cd VMs" shows "VMs" and "cd vms" shows "vms"??

Also if i open up the Hyper-5 Director on my Workstation and browse with "audit disk" the name is lowercase. Merely there are others that are all upper-case letter.
Ah, I see that. Aye does the same on my machine, folder proper name is Test, but if I cd TEST so information technology shows every bit TEST. Since folders and files on Windows are example insensitive it is going to the proper folder, so you should non have whatsoever problems.

Different in Unix/Linux where you can take two files called Exam and test because information technology is example sensitive, Windows is case insensitive so y'all tin only have 1 file in a folder chosen Test, equally test and TEST will all exist the same.

If you lot observe that my postal service has answered your question, please marker information technology equally the answer.

That is purely a upshot of the way PowerShell sets the electric current path. It sets it using the string as you lot typed it. The folder proper noun volition always exist the exact casing you used to create information technology. TO prove this just await at the folder in File Explorer.

THe same effect does not happen on CMD

I constitute something like this to be ridiculously hard in powershell, renaming folders to uppercase. I ended up invoking cmd. You lot could put "write-host" in front of "cmd" to exam out what strings would be run. This thread had the almost "google juice" for this topic.

get-childtiem -recurse -directory -path "parentfolder" |
foreach { cmd /c ren $_.fullname $_.proper name.toupper() }

Unnecessary.
```
Get-ChildItem $parentFolder -recurse -Directory |     Rename-Detail -NewName {$_.proper noun.toupper()} -WhatIf
```
Simpler and much faster.

If you were to really remove the -whatif, you would see how information technology errors out.

Rename-Particular : Source and destination path must be dissimilar.
At line:2 char:5
+     Rename-Item -NewName {$_.name.toupper()}
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Yes. Now nosotros take a bug in the Internet Framework that does non allow this. Nosotros can no longer rename an item to its uppercase proper name or to its own name.

Too bad.

Howdy,

can yous tell me the significant of: cmd /c

I suppose that ren => rename-detail
/c but runs a command with cmd.exe then exits.
what is the difference between your code and mine?

$chemin = "C:\users\administrateur\Desktop\mon_dossier"

$LesRepertoires = get-childitem -recurse -path $chemin -directory

foreach ($rep in $LesRepertoires )

{

rename-item -path $rep.fullname -Newname($rep.name.Toupper())

}

Practice y'all want to write the line ( foreach { cmd /c ren $_.fullname $_.proper name.toupper() }) without alias?
I am using cmd.exe, not powershell.exe. Ren is a completely dissimilar command than rename-item. You can as well write "rename".
