an automatic capitalization of letters issue

Dan Beaver
 

I am running Windows [Version 10.0.19044.2130]. I am running NVDA version 2022.3.


I don't know if this is a Windows issue or a NVDA issue.


I tried renaming some files on my hard drive.  Each of these files start with the letters "CFM".  I wanted to rename them so the beginning letters were "cfm".  Renaming from uppercase letters to lower case letters.


After doing the rename I checked and the system is changing them back to uppercase letters.  I check before pressing enter and made sure they were lowercase but it isn't staying lowercase.


Is this something in Windows or is this something in NVDA?  Does anyone know how to get it to keep them as lowercase letters?


Thanks.

Dan,

The first thing you need to understand is that, as far as Windows is concerned, case does not matter.  Windows is case insensitive.

This means that if you have a file CFM-123.txt and attempt a rename to cfm-123.txt nothing is going to change because those two are precisely the same name in the eyes of Windows.

You either have to do this as a 2 step process if you're doing it by hand, like naming the original CFM file as FMC blah blah blah, then renaming it again to lowercase cfm blah blah blah, or add a character somewhere in the filename ahead of the extension that actually changes the filename in the eyes of Windows.

If you are comfortable with the command prompt, and very many files are involved, the use of the REN (rename) command with wildcards comes in very handy.  You would give two rename commands:

REN CFM*.txt TEMP*.txt
REM TEMP*.txt cfm*.txt

Whatever the asterisk wildcard catches in the original filename will be used in the same spot you put the asterisk in the replacement filename.  With those two commands, using the appropriate prefixes to catch the filenames you want, you can rename many, many files in a simple two steps.

Ok, never mind.  I accidentally came across the answer.  It turns out that if you rename a file and all you do is change the case of some letters the rename isn't performed.  Seems like a stupid decision on somebodies part in my opinion but then again they do not ask me about these things do they. :)

Thanks Brian,  I was looking for something else to do with files and came across the answer.  Couldn't find it before since I guess I was searching for the wrong terms.


Thanks again.

This is true not only under Windows, but under any operating system that is case insensitive.  There are others.

And if you are used to only Windows or another case insensitive OS, it comes as quite a shock when you first encounter two files with names differentiated only by a case change in one or more characters.  The initial thought is, "WTF!?"

Since I've been working with both case sensitive and case insensitive OSes for years, neither system seems weird to me.  I just remember which OS has case sensitivity or not.

I don't know why it is happening.  Windows doesn't care if letters are upper or lower case.  It treats them exactly the same in file names so you don't have to worry.  The case should change.  I don't know why it isn't.

I just tried changing the case of one letter in a filename using the Windows rename command and it worked.  I changed the a in Winamp from a small a to a capital a and the change was accepted. This is in Windows 10.  I backspaced to remove the a, then typed a capital a, then pressed enter. 

From my experience, it appears that what you saw in a search isn't correct.

Before sending this message, I tried changing one letter in another filename and it, too, was changed.

I have tried this in both Command Prompt and in File Explorer and changing the case of one or more letters results in no filename change of any sort under Windows 10, Version 21H2, Build 19044.2130.

And I tried hitting F2, changing a single letter from lowercase to uppercase, and afterward the original filename is what's presented.

Windows is case insensitive, which means changing case means changing nothing.  And under any OS renaming something to its existing name doesn't change anything.

Yes I do find it odd, even now since my old days of home computers, how one cannot rename in this way for the human reader. IE they could be treated the same, but if you wanted to use a cap at the start of a word, similar to some variable names in Python, you at the mercy of the OS rename command at the moment.

Hmm, well there are certainly cases where they aware not, and it makes the thicken as they say. Could it be perhaps that part of windows thinks the file is still in use but then it should give a warning, even if its telling lies. I have not got time to investigate the different occasions it works one way or the other just now.

I just realized that it may be difficult to do a print screen on this computer.  My keyboard, instead of having the three standard, in their function, keys on the upper right such as print screen, scroll lock, and the other, which I don't recall, has keys that control the volume and mute and unmute audio instead.  I suppose there is some combination of keys that allows these keys to function as normal, but I don't know what this keyhboard provides,

Just popping in to confirm that my experience of case sensitive
filenames is exactly the same as Gene's. I can name a file in all
caps, all lower case, or a mixture of caps and lowercase. I can't
remember a time when files in Windows couldn't be named with a mixture
of uppercase and lowercase letters, and where you could change one or
more of them and the renaming would be retained. I've used most
flavours of Windows in my time - 3.11, 95, 98, XP, Vista, 7, and am
using 10 at the moment. I do have some text files that I created in
DOS, back in the days before Windows, and they are all lowercase and
with a maximum filename length of 8 characters plus the 3-character
file extension. I too use WinAmp, and that is the case choices I use,
a capital W and a capital A, but I can change it to winamp (all
lowercase), Winamp (only capital being the W) or winAm (only capital
being the A).

However, Windows does not recognise any difference between the
filenames. If I create a copy of a file, delete the " - copy" that
Windows adds, and then change one letter, such as in the address of a
house I used to live in on Flaxland Avenue ... if I change the capital
F of Flaxland to a lowercase f, then Windows tells me there is
already a file of that name and, if I agree I want to proceed, it will
append (2) to the end of the filename before the extension.

I know this doesn't really shed any light on the question of why a
Windows user might not be abel to rename a file by changing the case
of one or more letters ... my only thought is whether NVDA isn't
currently set to Beep or say :Cap" to indicate a capital letter. I
know I have never found the pitch change to indicate a capital letter
easy to detect with the synth I use (SAPI5 Zira).

Odd, I can do this , I can say for example Flight from KRSW-KMIA or flight from krsw-kmia and both will be case specific in windows. I should say I name the files in my editor first. I've even done this using ffmpeg.

the command is alt win scroll lock. The pictures will be stored in captures under videos. Since I changed the location of such I can’t help there, however use the search tool to find captures.

of uppercase and lowercase letters, and where you could change one or
more of them and the renaming would be retained.

The problem is, no one has claimed anything about the ability to use mixed case, you have always been able to do that.  But windows is case insensitive as far as file name recognition.  You can't have a file named one.txt and ONE.txt as separate files in a single folder because, as far as Windows is concerned, that is the same file.  So is One.txt, oNe.txt, ONe.txt, etc.  

What's interesting is that as I'm experimenting further based on Gene's specific example, I can get EXE files and DOCX files to accept case changes exactly as Gene described, but only if they are on my C: drive.  If I have copied them to external storage like an SD card, they won't - whatever their original character cases were, regardless of how you manipulate them in a rename after it's done, Windows still shows the same name you started with.  You can do the rename, but the filename does not change after hitting enter (if using File Explorer) or running the REN command.  I have no idea why it will apply that change in one context and not another.  I did all of my testing yesterday on a set of files on an SD card, not my C: drive.  This morning, I went and found a JAWS installer on my C: drive to perform a change like Gene noted, and lo and behold, it worked!

But you can create a file named one.txt (all lowercase) in one folder, and ONE.txt (all uppercase ONE) in another, and if you try to copy and paste in either direction you'll get the standard warning, "Destination already has a file named . . .," and asking you if you want to replace the file, skip it, or compare contents.

You can, of course, use mixed case in file names, it's just that Windows doesn't care about that as far as distinguishing one file from another.  That's what case insensitivity means.  And other OSes are not case insensitive.  Any Linux distro you may have ever played with is case sensitive.  I believe MacOS is case sensitive.  And since Android is based upon Linux, it probably is, too.  On case sensitive OSes you can have one.txt and One.txt in the same folder because as far as the OS is concerned that's two distinct file names,  Windows doesn't see it that way.

Sarah,

Please see my most recent post before this one.

I know you can do that although I didn't know you could make a case change stick as the only change to a file name.  And it appears to be something that works on the system drive (probably all internal drives, but this computer doesn't have a second internal one so I can check) but not on removable storage of the SD/USB Flash types.

But, again, if you have file:
Flight from KRSW-KMIA
in one folder, and file:
 flight from krsw-kmia
in another, and try to copy either one of those to "the other folder" you will get a warning that the file already exists.  This is because Windows does not distinguish file name uniqueness based upon case.  That's what defines case insensitivity.

It's not that you can't use upper and lowercase letters alone or in combination in a file name, it's just that Windows considers that the same name.
