Same for me, XD apparently produces lot of rubbish on the drive. The workaround is to go to Advanced options and click Reset, the space will be released then.
Hi there, I can't find advanced options in XD , You mean on Creative cloud app ?
Will the reset will reset my apps also ? I have so many plugins installed , i don't want to reinstall
This is in App Settings (Right-click Adobe Xd > App Settings).
Edit: Resetting it will remove your plugins (thanks Martin)
The space taken is mostly thumbnails and cached artboards. You can also try to manually delete the folder with the thumbnails, which takes most of that space. I've discussed it with another user in this thread. This will not remove your plugins.
In my case it removed all plugins and cleared the list of recently opened files, both OK for me. The important thing here is that XD runs much faster now (at least for a while).
