Get back lost shelf changes

You can restore the state of those files if they were edited in IntelliJ. Use local history to see all the changes made in IntelliJ (VCS -> Local History -> Show History).",

Even there isn't Shelf tab in IDE you can find shelved changes as patch files at {ProjectName}/.idea/.idea.{ProjectName}/shelf/.idea/shelf. \n\nThen your can apply any selected patch.",

I was able to view lost changes and revert back to them by:\n\nright click on project directory, select Local History > Show History\nFind the entry in the history menu that you want to restore. You can examine the files by double clicking on the entry and the files to examine differences.\nRight click on the entry you want to restore, and select Revert\n\nNote in my case Git>VCS Operations>Show History showed nothing. Only through the Project Files menu.",

Andrei's answer was helpful for my situation where I renamed my project and my previously shelved changes were no longer found under the shelf, but I did run into an issue when applying the patch file because I was prompted to "Select missing base" for various files in the patch. Similar to what is seen in the screenshot below:\n\nhttps://youtrack.jetbrains.com/issue/IDEA-183910\nI was able to avoid having to "Select missing base" for various files by first changing the default shelf location and then applying the patch.\n\nhttps://www.jetbrains.com/help/idea/shelving-and-unshelving-changes.html#change-shelve-location\nAlso, I found my patch in this location:\n{ProjectName}/.idea/shelf\n\ninstead of the aforementioned location:\n{ProjectName}/.idea/.idea.{ProjectName}/shelf/.idea/shelf\n",

Maybe this will help someone:\nI lost part of my shelved changes in combination with an update of IntelliJ. I'm not sure if the update was the reason but eventually most of my most recent (and important) changes were gone.\nI couldn't restore them from local history as this does not "survive" an update of IDEA. But in the files I saw that there still is some data:\nC:\\Users\\myUser\\AppData\\Local\\JetBrains\\IntelliJIdea2021.2\\LocalHistory had a changes.storageData with ~50MB.\nCopying the files to the folder of the new version didn't help as the files got overwritten again.\nSolution:\nI was able to get the old version of IntelliJ (2021.2) here and installed it. This can be done in parallel, without removing the newer version.\nHere I was able to retrieve my changes from the Local History and shelve or apply them again.\nHint: Backup the "Local History" folder (or the whole IntelliJIdea20xx.x folder) before you start. I don't remember if I had to copy it in there again or if it worked out of the box. (Just to be sure the local history doesn't get lost).",
