how to create in-memory folder in java

Question

how to create in-memory folder in java. I have a requirement of creating a folder in-memory and then write files in it. Is it possible? If yes how?

Do you mean like a "virtual drive"? – Steve Smith Aug 30 '17 at 13:37 — Steve Smith, Aug 30 '17 at 13:37

In plain java (before java 7) i do not think is possible, however you could use the apache common vfs library which has a RAM file system type. In java 7 and above (as suggested by @ervin-szilagyi) you could implement your own FileSystemProvider

Hope this helps.

Actually you can in Java 7 and above: http://docs.oracle.com/javase/7/docs/api/java/nio/file/spi/FileSystemProvider.html – Ervin Szilagyi Aug 30 '17 at 13:41

I am not quite sure about the term "in-memory folder" but I would guess you mean temporary files and directories?

If that is what you are looking for then this question should help you: How to create a temporary directory/folder in Java?
