I got the following error that started popping up:
internal error in mingw32_gt_pch_use_address, at config/i386/host-mingw32.c:190: MapViewOfFileEx: Attempt to access invalid address.
exit status 1
Compilation error: exit status 1
I got it to go away by deleting the temporary files in my user appdata folder.
I have done a lot of compilations since I last deleted it. It would appear at some point the shear volume causes things to break.
But all good now.
Some improvements were made in the Arduino IDE 2.0.4 release related to cleaning up temporary files:

## What kind of change does this PR introduce?
The build files saved under temporary folders gets cleaned regularly if not used.
## What is the current behavior?
Unused files remain stale in temporary folders until the os decides to eventually remove them
## What is the new behavior?
After an amount of compilations the built files are deleted if they were last used before a period of time.
The number compilations before the purge is triggered and the maximum age of the files are configurable with the following environment variables:
- `ARDUINO_BUILD_CACHE_COMPILATIONS_BEFORE_PURGE` (0 signifies never purge, default to 10)
- `ARDUINO_BUILD_CACHE_TTL` (default to 30 days)
This does only apply the default, temporary, build path. It does not purge files under user-specified locations, outside of the default one.
The default directory structures is also changed from:
```

### Describe the problem
The Arduino IDE application creates some temporary f… olders:
- Name format: `arduino-ide2-0694b57a37dbff387afae61891204d75/`
- One folder created for each IDE window that is opened.
- Name format: `.arduinoIDE-unsaved202301-12372-u0dvfq.rtr7i/`
- One folder created for each unsaved sketch
- Name format: `gdb-server-console-6800.log`
- Created by the [**Cortex-Debug** extension](https://github.com/Marus/cortex-debug)
- Name: [`github-remote/`](https://github.com/eclipse-theia/theia/blob/v1.31.1/packages/plugin-ext/src/main/node/plugin-github-resolver.ts#L39)
- Name: [`http-remote/`](https://github.com/eclipse-theia/theia/blob/v1.31.1/packages/plugin-ext/src/main/node/plugin-http-resolver.ts#L37)
- Name: [`theia_upload/`](https://github.com/eclipse-theia/theia/blob/v1.31.1/packages/filesystem/src/node/node-file-upload-service.ts#L55)
These persist even after the user exits the IDE.
In the case of the first two on the list above, the folders accumulate over time, which may eventually cause a performance impact.
### To reproduce
1. Take note of the contents of your temporary folder.
- Windows:
```text
C:\Users\<user name>\AppData\Local\Temp
```
- Linux:
```text
/tmp
```
- macOS
```text
$TMPDIR
```
1. Start Arduino IDE.
1. Select **File > New** from the Arduino IDE menus.
**ⓘ** This is treated as an unsaved sketch.
1. Select **File > Quit** from the Arduino IDE menus.
1. Examine the contents of your temporary folder.
🐛 An additional folder is present for each of the IDE windows you opened.
🐛 An additional folder is present for each of the unsaved sketches you opened.
🐛 An additional `gdb-server-console-nnnn.log` file is present for each of the IDE windows you opened.
🐛 The `github-remote/`, `http-remote/`, and `theia_upload/` temporary folders Arduino IDE creates are still present
### Expected behavior
Temporary files are cleaned up on exit.
### Arduino IDE version
76f9f63
### Operating system
- Windows
- Linux
- macOS
### Operating system version
- Windows 11
- Ubuntu 22.04
- macOS Ventura
### Additional context
This is similar to https://github.com/arduino/arduino-ide/issues/1779. However, the two are distinct in that https://github.com/arduino/arduino-ide/issues/1779 allows for easier management of the temporary files during runtime (e.g., configuring antivirus software exclusions) and manual cleanup of files leftover when the application is not able to perform an automatic cleanup (e.g., power outage, crash).
---
Some operating systems may eventually do a clean-up on the temporary folder, but this is not guaranteed. It is better for the application to take care of clean up of any temporary files once they are no longer needed.
---
Additional temporary files are generated by tools used by Arduino IDE (e.g., [**Arduino CLI**](https://github.com/arduino/arduino-cli), [**arduino-fwuploader**](https://github.com/arduino/arduino-fwuploader), [**Arduino Language Server**](https://github.com/arduino/arduino-language-server), [**clangd**](https://clangd.llvm.org/)). Cleanup of those file should be the responsibility of the individual tool, not Arduino IDE, so cleanup of those files is out of scope for this issue.
They are tracked in the repositories of those projects:

- [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-ide/issues?q=)
- [X] I verified the problem still occurs when using the latest [nightly build](https://www.arduino.cc/en/software#nightly-builds)
- [X] My report contains all necessary details
I remembered the "Temporary Files are not cleaned up" post, but couldn't locate it to cite it.
I have been using 2.0.4 since it was released, so even the improvements that were made can be negated if pounded on long enough (I had somewhere above 1GB of temp files, almost all IDE related). I was on a roll and wrote a lot of code, with lots of compile/verify iterations.
Did you clean up the temporary folder after updating to 2.0.4? The bulk of the accumulation there might have been from previous Arduino IDE versions.
I think the temporary files come from a previous version, try to clean it up and check if it's still happening.
Well, I deleted Temp yesterday, I am only running 2.0.4 (exclusively), and now there are 200 MB of files in Temp. From one day's work.
Some are other things, but the majority are IDE related items.
Now that I know it can create problems long before the disk itself gets full, I can empty it.
That might be a good practice to follow.
I realize I was not as specific as I should have been about the Temp files location in my first post.
There is a Tmp directory in the Appdata/Local/Arduino15 folder in my user data, that is empty.
It is the Temp directory in the Appdata/Local folder that keeps growing.
I cleared it all, did one compilation with 2.0.4 and what did I find?
That is why my problem running the IDE happened... eventually this grows from 36 MB to hundreds.
I suggested on github that all temporary fikes should be stored in a dedicated directory; it's now partially implemented. This does not solve the issue of it growing but at least there will be a single directory that can be deleted when needed.
There can be various reasons why it's not cleaned up. The IDE (in the broadest sense) is sloppy is the main reason in my opinion, OS and antivirus might also prevent temporary files from being deleted.
Thanks for the information... I just can't seem to keep up with GitHub.
I can be patient on this... it takes quite a few of compilations to get to the "makes an error happen" stage. And now I know to check Temp regularly.
Still, one more PITA thing to do.
The creation of the folders like 55770067919477794103602099745
has already been fixed:

## What kind of change does this PR introduce?
Code imperfection fix
## Wh… at is the current behavior?
Temporary files and directories created running the command `arduino-fwuploader firmware list` are not cleaned up on exit. There are two reasons behind this behavior. The temporary directory with a name format `55770067919477794103602099745` is not cleaned up because the `DownloadIndex()` function is trying to remove an empty directory (which is not), silently failing while doing so. On the other hand, the removal of `fwuploader` is never addressed.
## What is the new behavior?
Temporary files and directories are correctly cleaned up on exit. The directory named `fwuploader` is removed by the function `GetFirmwareIndex()` because doing it prematurely in `DownloadIndex()` would cause the command to fail.
However, there hasn't been a new release of the "Arduino Firmware Uploader" tool since that time so the fix hasn't propagated into Arduino IDE yet.
The arduino
folder is the dedicated folder for temporary files produced by Arduino development tools, as proposed by sterretje :

### Describe the request
IDE 2.0 leaves a lot of directories files behind in … (Windows system) `C:\Users\yourUsername\AppData\Local\Temp`. Request to collect them all in one dedicated Arduino directory.
If the cause is a virus scanner that prevents cleanup, it's safer to just exclude on directory instead of the complete directory.
If the cause is Windows or the IDE, it's easier to manually clean up at occasion.
### Describe the current behavior
Directories and files that can be found in `C:\Users\yourUsername\AppData\Local\Temp`
* Files `C:\Users\yourUsername\AppData\Local\Temp\.arduinoIDE-unsaved*`.
* Directories `C:\Users\yourUsername\AppData\Local\Temp\longNumber` (e.g. 5577006791947779410206689246) with files `index.gz`, `index.json` and `index.json.sig`.
* Directories `C:\Users\yourUsername\AppData\Local\Temp\longNumber\arduino-ide2-longHexNumber`; directories are empty
* Directories `C:\Users\yourUsername\AppData\Local\Temp\arduino-language-serverNumber (e.g. `arduino-language-server525288423`).
* Directories `C:\Users\yourUsername\AppData\Local\Temp\arduino-sketch-longHexNumber` (e.g. `arduino-sketch-07DD36AA0DA5BBED7460DCF645FC5952`).
* Files `C:\Users\yourUsername\AppData\Local\Temp\dd_updateconfiguration_yyyyMMddHHmmss.log`
* Files `C:\Users\yourUsername\AppData\Local\Temp\gdb-server-console-number.log` (e.g. `gdb-server-console-5992.log`).
* Files `C:\Users\yourUsername\AppData\Local\Temp\system-includes-number.clangd (e.g. `system-includes-75256d.clangd`)
* ico files
Note
Above list from IDE 2.0.3; I haven't consistently used the nightly build to be sure if the list has not changed significantly but a number of the above directories and files are certainly there.

Compilation caches are intentionally preserved in that folder so that they can be reused during subsequent IDE sessions. So it is intended that there will be some files left over in that folder. However, there is now a periodical cleanup of caches that were not recently used to limit the accumulation:
