Crashing on start

Describe the problem

Failed to start the electron application.
Error: EISDIR: illegal operation on a directory, realpath 'Z:\Temp'

The Z drive I use is actually a ram drive which I created using ImDisk. The reason is, of course, even though I have 128GB of memory apps love to thrash the drives temp files so I use ramdisk to avoid this and it typically speeds up some applications.

To reproduce

Do as you like

Expected behavior

For it to work.

Arduino IDE version

nightly

Operating system

Windows

Operating system version

Latest

Additional context

This technically may be an issue with ImDisk or with node or whatever Arduino uses.

E.g., every once in a while I have an issue with some apps not working well with the temp dir being on a ramdisk. E.g., some recycle programs do not work well because the drive is not NTFS(does not contain a $recycle dir).

There technically should be no reason it shouldn't work though. I use thousands of programs and almost all work fine(from more complex apps like various IDE's to graphics apps to whatever.

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

I was able to "solve" this issue by temporarily changing the TEMP env variable to a different drive.

Have you tried formatting the Ram disk as NTFS?

imdisk -a -s 512M -m X: -p "/fs:ntfs /q /y"

-a initializes the virtual disk.
-s 512M is the size, 512 MegaBytes.
The full choices are b, k, m, g, t, K, M, G, or T.
These denote a number of 512-byte blocks, thousand bytes, million bytes, billion bytes, trillion bytes, KB, MB, GB, and TB, respectively.
-m X: sets up the mount point a.k.a. the drive letter, X:.
-p "fs:ntfs /q /y" formats the drive.
-p's parameters are actually for Windows' format program.
So, if you want the RAM disk in a different filesystem, just change ntfs to fat (FAT16) or fat32 (FAT32).

Note: I use Linux so the above was just a google search for "imdisk ntfs"

I tried it a long time ago but there were more problems with NTFS. I don't recall what they were but I would have used it instead if it worked right. Some other apps I use for other things fail also. E.g., if I use a recycle app to delete files to the recycle bin it will fail since obvious it doesn't exist on the drive.

The workaround works fine for me so I'll just keep using that.
