Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Why do deleted Content Browser folders reappear?

Hi, When I delete a folder in the content browser a redirector will be created and I have only one map. Why does this happen? There is nothing "old" who needs to know the new location(only one map). After a restart of UE4, the deleted folders with the redirectors reappear in the content browser. It is realy annoying. How can i delete the folders for ever? "Fixup Redirectors in Folder" doesnt help, and I dont want to experiment with manual deletion in the explorer.

Hey EternalWalker,

Did you rename the folder or any files inside that folder before deleting it? If so, it might be one of our known issues with Redirectors, mentioned here:

https://docs.unrealengine.com/latest/INT/Engine/Basics/Redirectors/index.html

Try doing the Fixup and then deleting the folder, then close/reopen the project and see if that works.

avatar image Nhorth Jun 05 '14 at 08:12 AM

thanks for your fast answer. I used the Fixup many times, but it doesn't help.

Example:

Folder named "Character", I rename it to "Characters" and then i have two folders. One folder Character with empty sub-folders and one folder Characters with all assets. And if i want to delete the Character folder UE4 thinks the assets still exists in the "Character" folder and i can only delete it with force-delete. Then i save the Content Browser and use Fixup. After that i can delete the "Character" folder. But when I restart the editor the Character folder with the sub-folders reappear. The same happens if I move a folder to a different location.

(my project location: C:\GameDev\UnrealProjects )

avatar image Ben Halliday STAFF Jun 05 '14 at 12:41 PM

Can you try it again, this time doing a Fixup before your deletion? Thanks!

avatar image Nhorth Jun 06 '14 at 11:32 AM

I did Fixup before and after deletion. I can reproduce this bug. When i use the ThirdPerson-C++-Template and move the textures folder to another location, the Textures folder stays at its location and i create a new folder with the moved assets at the desired location. Its weird. And i dont know how to delete the Textures folder at the old location.

Maybe UE4 needs some rights? Maybe he cant delete this stuff? Or a problem with the redirectors?

I think it has something to do with that: The redirectors doesnt disappear and the content-explorer shows all folders with files. And i cant see the redirectors in the content browser. The result is, that i have old empty folders, which reappear every time UE4 checks the project folder structure.

Or maybe it has something to do with blueprints/materials, all stuff that needs to be compiled. The redirector doesnt disappear because the blueprint only knows the old location?

Maybe move this to the bug reports section?

avatar image Ben Halliday STAFF Jun 24 '14 at 06:38 PM

Hey EternalWalker,

Sorry for the delay in response. There is a bug in our database that involves redirectors requiring two Fixups before they can be deleted and I thought that may have been what you were running into here, but it looks like this might be a separate bug. I will enter a new bug for folders remaining after deletion. In the meantime, the only way you'll be able to remove the folder will be to find it in Explorer and delete it manually. Just be sure that you've removed all references beforehand!

Best,

Ben Halliday

Any updates on this? Got the same problem. Deleted folders are automatically restored after each project load (fix redirections didn't change anything)?

avatar image Nhorth Jul 20 '15 at 10:15 AM

Its not fixed. The folders doesnt get deleted in the windows explorer. This causes the reappearance of the folders in ue4. I need to delete this manually. Really anoying to keep the project clean.

avatar image Ben Halliday STAFF Jul 20 '15 at 06:01 PM

Sorry, no update yet. The bug is still open in our system (UE-11796). I'll post here when I see any change.

  • same issue in multiple projects. Bug still exists in 4.9.2 even after multiple "Fix Up Redirectors in Folder", and multiple editor restarts.

avatar image devast3d Dec 30 '15 at 10:50 PM

4.10 and the bug still alive. I guess it's some kinda core feature now...

avatar image dzodzu Feb 06 '16 at 05:36 PM

Any news on that? 4.11 and still renaming or removing folders is a bizzare hardcore thing..

avatar image Ben Halliday STAFF Feb 07 '16 at 04:06 AM

There is no update at this time.

avatar image Neutronux Feb 19 '16 at 04:33 PM

It's pretty difficult to keep a project slim and clean if you have to fight against those anoying zombie-folders. Is it save to delete your folders in windows-explorer? Or does it mess up other (redirection) stuff if you do that? Sometimes I don't really know anymore what's there and what just looks empty. For example if an fbx import failed for some reason, and you fix the fbx and reimport to the "empty" folder than you could crash UE4 editor.

avatar image Ben Halliday STAFF Feb 19 '16 at 10:56 PM

I did a little digging through our bug reports, and found another that covers this better (UE-14559). However, it's been fixed since 4.9. As long as you're aware of the information in this documentation regarding redirectors, and the Content Browser's Filter ability to search for redirectors, you should be fine.

If you run a redirector fixup, it should remove these redirector files as expected, even when fixing up references in unloaded maps. Replacing references in maps in place is more complicated; for now, Replace References continues to leave redirectors. Maps can then be fixed up without issue.

Deleting redirectors manually in Windows Explorer is dangerous, and I'd definitely consider making a copy before doing so in case any references are broken when doing so.

If you're still having issues in 4.9 and newer engine versions, please be descriptive in your process and give me steps to follow to recreate the issue. Thanks!

I could not confirm this. "Show Redirectors" does not show anything.

Steps to reproduce: Create new third person project 4.10.4 - no starter content: "TestProject"

Export the SK_Mannequin.fbx to the windows desktop (just to get same mesh to reproduce)

Create a new folder below "Content" called "Import"

Import the SK_Mannequin.fbx from the windows desktop into the Import folder

Create new subfolders Import/Materials, Import/Misc, Import/Skeleton

Move the skeleton of the import to Skeleton folder, materials to Materials, physical asset to Misc

Open the imported (and moved) skeleton, open the retarget manager, select humanoid and save the skeleton.

Do the same with the original UE4_mannequin_skeleton in Mannequin/Character/Mesh

Retarget the ThirdPerson_AnimBP from the Mannequin/Animations folder to the new imported skeleton via rightclick on the anim_bp

Click "Save All" and save all.

Close the project and open it again.

Delete the Import folder.

Close the project and open it again: The Import folder is back again.

Got to Filters->Misc->ShowRedirectors: Nothing here but "Drop files here or right click to create content."

Rightclick on "Import" folder and klick on "Fix up Redirectors in folder." Delete it again.

Close the project and open it again: The Import folder is back again.

Change the game mode to "Game mode", remove the Blueprints folder with the Third person BP and the Third Person Game mode.

Save all, restart the project. Finally even remove the origianl mannequin folder including the skeleton. So only the empty map and its meshes remain. Click "Fix up redirect" on any remaining folder (there are just a few left). Close the project and open it again: The Import folder is back again... even if the skeleton that was used as base for retargeting (including it's subfolders) could be deleted successfully, the imported mesh was never used and no redirectors show up.

Hello,

There is an issue in our database (UE-11796), that relates to folders not being removed completely from the Content Browser. Thank you for your report.

Have a great day

avatar image CleanCut Jul 21 '16 at 03:01 AM

Is UE-11796 ever going to be fixed? It's driving me crazy in 4.12.5

avatar image Etienne Andlau Feb 12 '16 at 03:30 PM

Hi,

Had the same problem. Go into your project folder. Mine is in MyDocuments on my Windows machine. You should see that folder you are trying to get rid of in there. Delete it. Now launch your Unreal engine again, open your project in it and it should be gone :-)

avatar image trepaning Feb 16 '16 at 07:57 AM

Deleting the folders worked for me, thanks.

avatar image KWS May 16 '16 at 12:04 PM

The editor just can't delete folders at all, it only temporarily hides them from the Content Browser. that's how simple this 3+ year old bug/annoyance is.

There are no redirectors, just empty folders. and the only way to remove them is by deleting in Explorer.

You could literally just create an empty folder in UE or Explorer. add nothing to it at all, then try delete in UE. nope, survives every time.

alt text

This message should be re-worded to explain that it is only temporarily hiding this folder from the Content Browser, not deleting from HD.

avatar image CleanCut Jul 21 '16 at 03:01 AM

Amen. Silly, stupid, very harmful-to-developer-experience bug.

avatar image hawkenfox Jun 19 '16 at 04:01 PM

This is super annoying , shouldn't this be like totally fix like right now since most user would depend on the content browser to keep their stuff organised? Get on top of this small but super annoying bug it's been years.

Fix please - new vote needed on website - still very unfixed. Thanks

avatar image Imagine-Games Dec 10 '16 at 03:31 PM

Not entirely fixed, was able to delete some folders in 4.14.1 and then it stopped deleting additional folders after the 3rd delete.

avatar image studiomagicalfox Mar 18 '17 at 11:28 PM

I am using 4.15 and having a terrible time migrating assets into a project from other workshop type projects then trying to move them to the proper place within the destination project. I have learned to never try to move or rename folders within the content browser as this will just result in a second folder being created and the editor will not allow me to delete the old one regardless of when or how many times i run the fix redirectors tool. Renaming assets and moving assets and folder structures around the content browser is broken. This is a huge problem since migrating assets also migrates their old folder structure and there is no clean way to place the incoming assets where they need to be.The problem becomes unmanageable when the assets have a complex set of inter-relationships which are bound to break if one resorts to the file system explorer to clean things up.

avatar image jellocube27 Apr 21 '17 at 02:21 PM

I'm having trouble with this particular bug today, as well - it's certainly not resolved... For those of us just learning how to manage larger project hierarchies, it is really a major frustration.

avatar image jimd667 Apr 21 '17 at 03:47 PM

can confirm as well, I now just plan waaaay ahead and decide what my folder structures will be before I commit to it. otherwise I will spend an entire day fixing everything before giving up and reloading a backup and just dealing with my old folder names.

We need another bug report to vote this as much as possible since this is a fundamental aspect of the engine that's still broken after years.

Hello everyone,

I cleaned up the post a bit due to an excessive number of answers, and wanted to provide an official update on this issue. This issue is currently in our system, UE-11796. It is being investigated by our developers; however, there is currently no timeline for when a fix will be released. Their efforts are currently heavily focused on high-priority crash and showstopper bugs. I will continue to provide updates regarding this issue as they become available.

Have a great day

The bug is still here after 2 years. Using the windows explorer to find and delete unused folders is not very professional when you work with over 2000 folders/sub folders . Every "2 years old bugs" which are associated with very basic usage of the engine are considered as low priority. I don't get it, why not fixing the old bugs first before adding new features leading to new bugs?

avatar image Sean L ♦♦ STAFF Sep 20 '16 at 03:39 PM

Hey Haoris,

It looks like the issue has been resolved for 4.14. You can track the status of the issue here: https://issues.unrealengine.com/issue/UE-11796

Have a great day!

avatar image Haoris Sep 24 '16 at 09:36 PM

Nice. There's so much little very old bugs like this one which can seams to be low priority for Epic staff but are really anoying for us (I had to buy a software only for this one)

avatar image Krzysiek_TATE Nov 17 '16 at 02:34 PM

I'm using 4.14 and folders are still appearing after being deleted/moved or renamed first. Sometimes I'm unable to delete them - especially if there are empty folders inside, then I have to delete them one by one first. Isn't Unreal Engine supposed to be mature enough, after so many years of development and so much cash inflow, to be free of such basic bugs?

avatar image yn3 Nov 27 '16 at 08:44 PM

Not sure why you have to vote for something so blatantly wrong and soul crushing.

avatar image John Alcatraz Nov 27 '16 at 10:43 PM

You don't have to vote, if you click on the link you see that it's already fixed and the fix will be in 4.14.1 :)

Hello,

I've tested and confirmed that this is still occurring, and as a result I have reopened the ticket.

Thank you for your report.

Yeah, this is definitely still an issue in 4.14.1

So, although it's not a fix to the engine itself, I've found a way to permanently delete the folders/content from the content browser so we can all avoid that clutter. Open up your project folder wherever it's located on your PC, mine is in my documents folder within the file explorer. Go into your content folder within your project and adjust your folders from within there. Deleted folders will stay deleted, moved folders will remain moved to their new locations without duplicating folders, etc.. I've tested on engines 4.11 - 4.14, this method works on them all. I don't know if anyone else has been doing this, but I didn't see it posted as a solution, even if it is just a temporary solution until the engine is fixed.

Again, it's not a fix to the engine itself, it's just a "desktop fix" that will help maintain that clutter within your project. Hope this helps.
