Purpose of .vmoptions files

This article is typically being linked as part of this troubleshooting article.

In your JDownloader install directory you might see a file called "JDownloader2.vmoptions".
If it doesn't exist, you may create it if needed.

This file is used to define the Java VM parameters for JDownloader.
Every line contains one VM parameter.
Lines starting with # are comments (= ignored).
Most of all times you would want to use it to increase the max. memory.

  1. Remove all -Xms and -Xmx lines if existent.
  2. Add a new line e.g. -Xmx2g (for 2GB max) or -Xmx1000m (for 1000MB max)

When starting JDownloader again you should see your defined -Xmx value in:
Help -> About JDownloader -> Memory -> See "Max:"

You can find more Information about Java VM parameters here but only change other parameters than the ones mentioned in this article if you know what you're doing!
