Created attachment 130130 [details] log file 1. Open attached project in Netbeans. 2. Rename Project JavaApplication1 to JavaApplication21 (Also choose rename folder). 3. Rename Package javaapplication1 to javaapplicatoin21 4. Repeat steps 1 & 2 changing 21 to 22. 5. close project and then reopen it. 6. Click undo button. 7. Click undo button again. 8. Notice that there is an extraneous folder created named JavaApplication21/src/javaapplicaion1 in the project directory on the system drive that is empty. This is not expected. Workaround: Delete the extraneous folder from system drive. See attached logfile and screenshot.

Attachment 130133 [details] (logfile 7.3 RC1) is the wrong log file. I will post the correct log file later.
Created attachment 130422 [details] correct logfile 7.3 RC1 (Build 201301172100) This time it also left an extraneous package folder "javaapplication24" inside of the valid project folder after undoing the renaming of packages.
Still valid in Netbeans 7.4, but not critical. I understand what is going on now, the renaming of a project and directory is not recorded by the Undo feature, therefore if you rename a file before this, it has no way of restoring just the filename, so it restores the entire file path. As far as I can tell from testing, there is not way it can overwrite a file in another package if a project is created with the same name, package name and file name as the renamed project because it will get undone first. The worst case senario is the package and file on an undo is merged with a project of the same name. The steps to recreate are easier: 1. Create any Java project with main class. 2. Rename the package. 3. Rename the project along with the folder. 4. Repeat #3 and #4 3 times. 5. With focus on renamed project, click Undo 3 times. Results is recreation of project/package on disk for each rename.
Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
