The IDE doesnt send the deleted project/file in Recycle Bin. It directly deletes with a confirmation message, which can be pressed accedentally. This results in complete project/file loss. In NTFS it is almost impossible to get that file/folder back via commercial undelete software.
IMHO, this is rather a feature. Reassigning to "projects"...
Accidentally ? When you press Del on project node (or invoke Delete Project action from menu) ID is asking another question about deleting folder from the disk (you need to check checkbox and press Ok (at least in current version). So I don't think it could be deleted "accidentally". So from my point of view - wontfix, but left on responsible developer's decision.
Friend i have not asked something strange, i just wanted a second level of security and that is if some how something is deleted it should go in recyclebin atleast on windows operating system, rather then totally disappearing. Windows users are fond of Recycle Bin so why are u taking it off from them when they use user superb IDE called netbeans! I hope u realize my point of view.!
Your use case is completly valid, but I'm afraid that it's not that easy in Java, there is no support for moving file to recycle bin. There is RFE for JDK http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5080625. Doing that in NB IDE would require probably JNI calls on windows and special handling of delete on different platforms. Changing to FEATURE, after there is support in JDK we might reconsider it.
This is a major flaw because an expected operation can result in an unexpected and permanent loss of information. It's unfortunate (but possibly expected) that the JRE would overlook such a critical platform flaw, but any serious desktop application must handle this issue properly even if it requires using JNI.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
