Check directory contents and assign then to variables - bash

Using Bash, how can I check the contents (archives, files, etc) of a certain directory, and assign them (their names) to different variables? Of course, first I need to verify if such directory exists, then check and display its contents, and finally assign them to variables. Thanks in advance.

File Path in Variable -> File identifier in File Content for Power Automate Flow

So I have this flow step and I want to replace hardcoded value of file identifier
with variable.
(Point where I call variable)
(How variable looks like)
Hardcoded path works, I tried it.
I want to set hardcoded path into variable and use it in steps like variable.
There are two operations for retrieving file contents, you need to use the right one when you want to use.
I created a basic variable with a file name ...
... and then tested with both types of Get file content operations in the SharePoint group.
You need to use the Get file content using path operation.

Windows show local path as list in the Environmental Variables pane

I like to modify my Windows environmental variables by opening the Advanced System Settings -> Environmental Variables. I particularly like that when I try to modify the system path (by clicking on System Variables -> Path), that I get a nice, easy to read list of the folders on the path:
However, when I click on the User Variables -> Path, I still get the old dialog, which is not very user friendly:
Is it possible to have Windows always display the list, as is the case for the System variables?
For what its worth, I think I remember seeing the desired behavior on a friend's computer, so I believe it should be possible.
EDIT:
It seems that having a variable as part of the path is the problem. Is there a way to get path list even when the path contains variables?
Context:
When I want to add a program to my path, I will create a new variable that redirects to its path. The reason to do that is simple... Programs typically have compound paths, and so making a consolidated variable seems like a wise decision. For instance, on my machine, I have multiple python instances (sometimes I need an Anaconda installation of Python 3.6, and sometimes I want a version of the bare-bones Python 3.5). To accomodate this, I create environmental variables for the paths to each installation.
Now if I want to switch which version is on my path, I can simply update my path variable from
path=...;%PATH_PYTHON35%
to
path=...;%PATH_PYTHON36A%
See how easy that was?
The problem is that the GUI doesn't seem to like this for the local variables. I can confirm that this is the case because when I remove the variables from the local path, I get the nice list like the System Variables case. However, what is perplexing to me is that the System Variables path DOES include some variables as well:
So I take this to mean that there must be a way of getting the local variables list to pop up, just like the System Variables case...
Guess I'm late to the party, but this works for me:
PATH=C:\DATA\bin;%JAVA_HOME%\bin
whereas this does not work:
PATH=%JAVA_HOME%\bin;C:\DATA\bin
A speculation based on my own observations.
It seems list view is only presented when at least one of the first two entries begins either with a drive letter notation (like C:\) or a specific variable. I'm not sure which variables are considered "valid", but here are a few environmental variables that show up as list:
%USERPROFILE%+%LOCALAPPDATA%;aaa;bbb;
aaa;Q:\%LOCALAPPDATA%;bbb;
These however show up as a string:
%LOCALAPPDATA%+%USERPROFILE%;aaa;bbb;
aaa;bbb;%USERPROFILE%;
Not sure what makes %USERPROFILE% different, but i tried a few other variables instead of %LOCALAPPDATA% (%OS%, %HOMEDRIVE%) - result was the same.

Command Prompt: Move a file to an Unknownly named folder

So, is there a possible way to move Test.txt to C:\ProgramData\CsD2\Tools\("Unknown Folder Name")\data\per Using command prompt?
using foxidrives solution for your previous question for detecting the correct directory, then just
move test.txt "%folder%\"
Short answer: yes. Not quite sure what the situation is that has left only the middle part of your path unknown, and the need to use the comnand line, but I have encountered similar cases on Linux and expect the algoirthm can be adapted to Windows commands. It's possible to do this by hand rather than writing a shell script, but it's up to you and your skills.
Permissions matter. Make sure you elevate yours enough to read and write in Tools before continuing.
First, change directory to C:\ProgramData\CsD2\Tools\
Presumably there are many items here. Some may be "hidden," so list the contents of this directory and be sure to include an option to show hidden files and folders. If you can, restrict the search to directories only.
It's tempting to display contents recursively in the above step. It's up to you, but I find it makes the output cluttered without a script to do the rest of the work.
Now it's time to search for the subfolder set that theoretically only exists in your target folder. Suppose Tools contains the directories fldr1, fldr2, and fldr3. Use your command to list a directory's contents with the path "fldr1\data\per", then use "fldr2\data\per", and so on until it doesn't return an error. Per may be empty, but that should look different from the path not found error.
Now you've found the name of your mystery folder. Write it down for future reference.
At thus point, you know the path to Test.txt, and the full path to the destination directory. Do a move command to relocate Test.txt, and you're done. I like to relist the contents of the target directory after to be comfortable that it arrived.

Store directory path in variable?

I want to store a path like c:\abhor\test in a variable but it is treated as \a,\t. I don't want to use c:\\abhor\\test. Please provide some solution to this problem?

Should environment variables that contain a executable-path with spaces also contain the necessary quotes?

When defining an environment variable (on Windows for me, maybe there is a more general guideline)
set MY_TOOL=C:\DevTools\bin\mytool.exe
if the tool is located on a path with spaces
set MY_TOOL=C:\Program Files (x86)\Foobar\bin\mytool.exe
should the environment variable already contain the necessary spaces?
That is, should it read:
set MY_TOOL="C:\Program Files (x86)\Foobar\bin\mytool.exe"
instead of the above version without spaces?
Note: In light of Joeys answer, I really should narrow this question to the examples I gave. That is, environment variables that contain one single (executable / batch) tool to be invoked by a user or by another batch script.
Maybe the spaces should be escaped differently?
I'd say, do it without quotes and use them everywhere you use the variable:
set MY_TOOL=C:\Program Files (x86)\Foobar\bin\mytool.exe
"%MY_TOOL%" -someoption someargument somefile
Especially if you let the user set the value somewhere I guess this is the safest option, since they usually tend not to surround it with quotes rather than do so.
If there are plenty of places where you use the variable you can of course redefine:
set MY_TOOL="%MY_TOOL%"
which makes things more resilient for you. Optionally you could detect whether there are quotes or not and add them if not present to be totally sure.
When your variable represents only a path to a directory and you want to append file names there, then the "no quotes" thing is even more important, otherwise you'd be building paths like
"C:\Program Files (x86)\Foobar\bin"\mytool.exe
or even:
""C:\Program Files (x86)\Foobar\bin"\my tool with spaces.exe"
which I doubt will parse correctly.
The command shell can answer your question: type C:\Pro and hit the tab key.
Autocomplete will leave all spaces as-is and add quotes around the filename. So, this is what is "officially" expected.
(this assumes that autocomplete is turned on, I'm not sure whether the default is on or off, but most people have it on anyway, I guess)
