Java creates temp folder with shortened path and throws 'Not found' exception when trying to access files placed in it

so I did run into one very weird issue. The idea is simple: create temp dir, place some files in it and then try to access them. Now the problem is that calling File.createTempDir() or Files.createTempDirectory(prefix) creates new file inside AppData/Local/temp with shortened path, so the full path to folder looks something like C:/Users/FirstNam~1/AppData/Local/Temp/myFolder/myFile.txt instead of C:/Users/FirstName LastName/AppData/Local/Temp/myFolder.myFile.txt.
The difference is that generated path inside java contains FirstNam~1 instead of FistName SecondName. Java then throws exception File Not Found.
When I try to copy and paste shortened path into file explorer I get an error saying that file does not exist, but if I do change shortened path to full one then file opens and it works as intended.
Is there any way to fix it? Ether by forcing java to use full path names or enabling something in windows? I did Enable NTFS long paths policy, but it did not help.
This is happening when using java 8/11 and windows 10 running on VM, project is using AGP and gradle. Temp file is created inside groovy file that extends Plugin<Project>

Just when I lose hope and create a ticket, couple hours after that I find the answer. So, java has method Path.toRealPath() which solves this ~1 issue. After using this method paths no longer contain shortening and are correctly resolved.
EDIT: looks like java is doing everything correct and paths are actually valid, problem did come from library that I'm using and it's a bug with it.

Find a directory in Android Studio Project not in the phone

I am trying to get access to a text file (log.txt) in a directory. All other questions on this topic refer to getting directories from the emulators internal storage.
My file structure is as such
>androidApp
->App
-->Build
-->src
--->game_log
---->log.txt
--->Main
---->(Android app Code further)
Using new File(System.getProperty("user.dir) + "app\\src\\game_log\\log.txt").exists() gets me false.
Another thing I tried was System.getProperty("user.dir") but that yields me /.
Contextwrapper.getPath() gets me the path of the emulators storage.
Is the file structure of Android Studio different or I am using the wrong method to get the file from my project folder?

How can I get Eclipse to find my .txt file in java ON A MAC? [duplicate]

I need to write a program that asks for the file name of a text document of number and then calculates average, median, etc., from this data set. I have written the program so that runs correctly when I input the full path such as "C:\Users\COSC\Documents\inputValues2.txt", however it will not run when I simply input inputValues2.txt. I have been researching the different between the two but am not fully understanding how to fix this. Since it is running correctly, otherwise, I don't believe it is a problem with the code, but I am new to this so I may be wrong.

Your program needs to know the full path in order to find the file. It isn't just searching your computer for the file "inputValues2.txt". It needs to know exactly how to get there. If you wanted to, you could move the file into your project folder, and then you would just be able to write "inputValues2.txt" to access it. I normally create a folder called "res" in my project folder, and then let's say I am trying to create an image:
Image i = new Image("res/img.png");

Your file should be in the class-path. That's in the same directory that your main class is in.
The suggested practice is to place it in a Resources directory inside your class-path, then you can access it via, "Resources/inputValues2.txt".

how to define a file path in java to make it ready for production phase?

I am writing a program in java with netbeans IDE which receives a jasper report *.jrxml and then displays the report for the user. I wrote the following line of code for the file path
String reportSource = "src\\jasper-reports\\report.jrxml";
but when I move the dist folder in some other place and try to run the jar file inside it, my program can not find the report.
my problem is that were should I put the *.jrxml file and how to define it's path in my program so that when I want to give my software to someone else it runs without any errors (e.g. the program can find the file)

avoid using absolute paths. try to include the file as a resource in your netbeans project. then in your code you can search for and load the file as
new InputStreamReader((Main.class.getResourceAsStream("/report.jrxml")))
something like that depending on where the file resides in your project

it's more recommended using one of the two approaches:
pass the locations/paths as a -Dproperty=value in the Java application launcher command line http://www.tutorialspoint.com/unix_commands/java.htm
store it the locations/paths in a configurations file with a unique key and edit the file accordingly for different environments,
e.g.this files always stored in ${HOME}/config_files/ directory
absolute paths considered a bad practice

Android - store and load files in project root

I am looking for an appropriate way to store and access pdf files in my Android app.
The problem is: I have 5 pdf-files which I would like to store in the project resources and load in the app.
I have tried to make a new directory in the project root /myApp/pdfs, and accessing it by:
File myFile = new File("/myApp/pdfs/,fileName);
I have tried some different variants of the path name: ./myApp/pdfs, myApp/pdfs, /pdfs, ./pdfs. However I get the same message stating that the file can't be found.
How do I get the path to my apps directory? And is this the most appropriate approach for saving a small number of pdf-files?

If you are wanting to load the pdfs from the app (while the app is running), you probably want to store them in the res/raw folder.
