The off topic guessable security topic has become a request as suggested by DecaTec !!! Justed need to wait for NC18 fix first !!! Off course.

You want security over "guesslinks", add f2a, or yubikey or password... no random odd policy from the past like the laughable "guesslink" reason...

humour mode on: in case of extra security needed against "guesslink", use a scissor... cut down the link.

Steps to follow to produce the problem:

1. Create some file, for example file_1.txt"
2. Share the file and change the name of the URL, for example "test1"
   2.1.- We can try if it's working.... https://myserver.com/s/test1 ....... YES
3. Delete the file "file_1.txt"
   3.1.- We can try if it's working.... https://myserver.com/s/test1 ....... NO, of course, we delete the file.
4. Create other new file, for example "file_2.txt"
5. Share the file and change the name of the URL to "test1" again.

Problem: The web page notice that this name it's in use.

Suggestion of improvement:
A little box asking to overwrite the share link or overwrite directly

It would be a great feature, if the share renamer would not only work in "file" mode, but also in "gallery" mode.

It does work with renaming it in "file" mode and using/copying the link in gallery mode. But you can't generate/rename the link directly in gallery mode.

For example:

• renaming https://nextcloud/s/waytoolongrandomlink to https://nextcloud/s/test123 works
• using https://nextcloud/apps/gallery/s/test123 instead of https://nextcloud/apps/gallery/s/waytoolongrandomlink works then
• but making https://nextcloud/apps/gallery/s/waytoolongrandomlink to https://nextcloud/apps/gallery/s/test123 directly is not possible, because there is no share link rename button in the share menu in gallery mode

Hi,

Any chance to cleanup token id database ? every time I try to rename a link ti says: a link share with that token already exist

Is this going to be updated for 14? Just wanted to check.

Thank you @JonathanTreffler for this great and useful app!

Would it be possible to make it compatible with the new Nextcloud 26 (Hub 4).

In my case, it is one of the apps that keeps me from upgrading.

Hello, are there any plans to make your awesome plugin available in NextCloud 27?
Thanks in advance.

Hello,
many thanks for your great work with this tool.
Today we have an issue with the reuse of a share name. First, we had a group folder wich was shared like a simple dropit folder. We gave it a simple share name. Because we had some issues with the folder we decide to unshare and delete it. After that we created a new normal folder and shared as a dropit folder too. As we tryed to rename the share identically with the name of the deleted groupfolder share name before, we get the message that the share name is allready used.
How can we reuse a share name such as in our case after unshared an other share?

The app needs to be changed due to changes in NC 18 (share API), see nextcloud/server#15719 and nextcloud/socialsharing@931efc9.

If a folder is shared and the link is named with the name of a user it does not work and the error is not notified.

Hello, thanks for your work!

I think instead of using a separate tab for the functionality the app provides, it would be cool if your could use the API that was introduced for and is used by the downloadlimit app:
nextcloud/server#28835

App should be flagged as incompatible with NC18+ seeing as it doesn't work there as referenced in #21.
Currently it's an available app to download with no warning message re: deprecation of function.

Hey,

how can I delete used links?
deleted a link and now I cant use the same name again for a new folder.
thx

Steps to reproduce

1. Create an empty folder foo
2. Create a new share link for foo
3. Set that link's permissions to read only
4. Rename that link to bar
5. Add a second share link
6. Set that second link's permissions to file-drop
7. Rename the second link to rab
8. Click the copy link button for both links and paste them somewhere

Expected behaviour

When I click the copy link button I want to have the corresponding link in my clipboard
When I click on the context menu button I want to see the permissions set for that link
Bonus: I want to see which link is which without clicking on rename to see the placeholder name

Actual behaviour

Both links end with rab
I only see the permissions for the rab-Link, the bar-Link has none of the radio-buttons marked

Does not work NC19

Hi, thanks for keeping this great app alive!

Please consider adding the ability to send a URL to a YOURLS instance via their API, which is fully open source and coded in PHP.
Here is the API documentation. And more general API and Hook documentation + info on the Passwordless API

Thanks either way!

I changed the share token to a human readable word. All works fine, exception one thing!

I'f I copy the new link the new human readable accesstoken/name ist copied, but If I klcik on share via eMail, the old share token will be used! :/

Just installed sharerenamer on Nextcloud 18. I don't see the edit field where you would enter the share's name. Happy to provide more details on request.

Nextcloud 26.01 installed on Ubuntu 22.04 LTS, full manual installation.

ShareRenamer was disabled after my upgrade from 25.06 to 26.01, and while I can enable it and it briefly appears in the active Apps list, it is almost immediately silently disabled again. I have tried uninstalling and reinstalling the app, and restarting the server, with no effect. No other apps show this behavior. I have installed ShareRenamer directly from the App Store.

Great project, and thank you for continuing it!

Would be nice if it was possible to search links through the nextcloud search. Clicking a result would then lead directly to the shared folder. Is something like this planned?

Sometimes we only know the "public link" but forgot where the actual folder is on the server.

I use curl to batch create shares via the OCS Share API: https://docs.nextcloud.com/server/latest/developer_manual/client_apis/OCS/ocs-share-api.html#create-a-new-share

Is there anything similar possible when using this app to batch rename the shares?

I just setup NextCloud for a new project. I always install Sharerenamer for all my NextCloud instances. However, in NC v28.0.2 when I enable the extension, go to a folder, share it, the Sharerenamer icon does not show. There is no way to create a new share link.

Hello,

I know that sharerenamer does not work for new links with NC18+, but will updating NC17 retain current working/renamed links?

Not really an issue, but we have customers that fear that updating will break their current links.

Kind regards.

I see this in log:

Only variables should be passed by reference at /var/www/nextcloud/apps/sharerenamer/db/sharerenamermapper.php#30

Nextcloud 17rc1
Php7.3
Apache 2.4

I'm using Nextcloud 17.0.0 with ShareRenamer 2.7.3.

I've previously created some shares and renamed them with the app. These shares have since been removed as shares, reshared and the directories are deleted. I've also removed the from the "Deleted files", as it was the problem on other issues posted here.

Now if I create a new directory, with the same name as a previous share, it immediately shows up under "Shares" (Menu on the left) and I can not reuse any share names.

Link 'test' already exists. Please choose another link name.

How can I fix this behavior?

This is a great feature! It's just what I was looking for. It works great on files in the Files app:

But we use other share links too, like shared Forms (using the Forms app):

shared Polls (using the Polls app):

and shared Calendars:

(We also use Deck, but that doesn't support Share Links (only sharing with a Nextcloud group) so I won't ask about it)

None of these share links can be renamed by sharerenamer.

I suspect I might be asking for a painfully tall order here, but is there a way to make this work with all share links, not just Files? The generated share links all look similar, except where files are like https://example.org/s/DrKci3ampPZmcKj, Forms are like https://example.org/apps/forms/s/DrKci3ampPZmcKj.

Thanks a lot whether or not you have any insight here!

Hi,
No doubt it is a very useful app, thank you for that. 👍:sparkles:
Is there a way to use this in NextCloud Mobile App ? I installed it today on my NextCloud server. On browser, I am getting the option to rename shared link but in NC Android App, if I click share, it doen't give me any option to rename the link.

If you open the sidebar and share a file, and then switch to the Share Renamer tab of the sidebar, it'll show up as blank until you refresh the page. Or go to another file and come back. It should ideally refresh its "knowledge" of the file's sharing status when the Share Renamer tab is switched to, instead of upon sidebar opening (which I assume is what's happening now).

ShareRenamer lets me create a long share name (35 character places), and when I select copy link icon, it copies the entire long link which doesn't work. The original link will work however if I truncate the url to 32 character places, so the link that is created has actually already been truncated to 32 character places, but the copy link icon generates an incorrect url.

How can i delete a Link?

I deleted a folder that was still shared and now I cannot use the same link

Thank you

Better visualization of messages (e.g. when link already exists).

Does it work for you?
The ShareRenamer 2.7.3 is marked as installed and active on my NextCloud 19.0.0 but it doesn't show up in the detail view of a file.

Sadly, I cannot maintain this app any further.

The app is only compatible up to Nextcloud 17. It will probably need some changes in the Nextcloud core code in order to make it compatible to Nextloud 18+.

Because I don't have the time to maintain this project any further, I'm looking for a new maintainer. If you're interested, please reply on this issue or contact me.

After renaming a Link neither the original Link nor the renamed one work. If I deactivate Shareramer the renamed Link is working.

That's a bit strange and it would be fine if you could have a look at it.

it's possible to assign same share name to different items

On my share, there is no Rename Share or something...

Especially for Nextcloud 14 compatibility, the rename function should move into the 3-dot menu of the share link. If you check out Nextcloud 14 you will see the layout changed:

So there should be an entry for "Change link" below "Copy link" which then opens the text field.

NextCloud supports to add multiple "Share Link"(s), imagining a user created several Share Link for the same resource, but having different permissions, they all displayed same. When this user wants to edit one of them, will have to click/and open them one by one to find out the link needed to edit.

If user can name those "Share Link"(s) to different meaningful text, will be a great improvement to the experiment.

It will be something like this:

• Share link for Alice (drop folder)
• Share link for Bob (read only)
• Share link for John (full access)
