Steps to reproduce

add file on another computer (macOS) or webinterface
Nextcloud sync client (2.3.3) on my computer (Linux) fails with "File name too long"

Expected behaviour

sync file

Actual behaviour

file is synced on other computer and server
file is not synced on my computer
error message is shown: "File name too long"

charaters: filename: 150 filepath: 211 (inside cloud folder) absolute filepath: 236 (in the filesystem)

if I reduce the filename to 144 chars the file gets synced as usual.

Nextcloud version: 13.0.4

There is no problem on the macOS computer, but on my Linux computer. May be this issue is related to Linux, ecryptfs, ext4.

esalgado commented 6 years ago

This happens to me as well. In file synced from a windows client, does not sync in Linux, ecryptfs, ext4 client.

rohlandm commented 5 years ago

I also tried to sync a folder encrypted using gocryptfs, and some files fail to sync because of "File name too long"

Edit: Server: 16.0.1, Debian 9, official Docker Image Client: 2.5.1, Ubuntu 19.04

akurzawa commented 4 years ago

Server 17, client 2.6 windows.

Filename too long Is it too long for nextcloud indeed?

zlukenic commented 4 years ago

same problem but error message is not god. File name is not to long it's just because there is strange caracter just before the file extension. in my case the file name was "BL PRET ATELIER INCUBES BLI21000 2017.05.03.pdf"

resolution: just rename file by deleting one caracter before the extension (.pdf)

alexanderdd commented 4 years ago

Ideally, Nextcloud Web interface should not accept file names (when you create/rename) that are too long, that would be an issue in server - anybody know if there is an issue about that already? I only found this but it is slightly different issue https://github.com/nextcloud/server/issues/4046

For the client, there should be a more helpful error message telling the user how to resolve the problem. Ideas:

"File name exceeds maximum of 255 characters"
"File name too long. Click here to truncate to maximum allowed length"

danielwbn commented 3 years ago

I have the same error: the linux client (v 3.0.2) fails to download files with long file names (in my case 140 chars). If I shorten the names in the web client (NC 19.0.4) they download fine. Also, I can create files with such long names (or rename the files after download to original long name) on the linux PC (ext4, ecryptfs) just fine and they do sync back to nextcloud server via the same client.

danielwbn commented 3 years ago

I just updated to NC client version 3.1.0 (Ubuntu) and still have the same error

danielwbn commented 3 years ago

NC client 3.2.1 still gives same error. However, I am beginning to think it might not be related to the NC client, but to my system. I have not investigated this further, but when I call "getconf NAME_MAX ./" (which I think returns the maximum filename length) in the sync folder in question (or in fact anywhere in my home dir) I get 143 in return. Calling "getconf NAME_MAX /" returns 255.

This happened to me a few days ago on Nextcloud 20.0.10 A long filename was created online but could not be synced to my linux machine with the error "file name too long"

mgallien commented 3 years ago

Can you test against the latest version of desktop client ? If you can reproduce it, we will need the desktop logs (at least) to be able to understand what is going wrong. If this is fixed, can you close the issue ?

danielwbn commented 3 years ago

nextcloud desktop 3.2.2, I get the same error. The log file is probably way too long to paste here (>50MB), but I think I found the relevant lines:

Hi,

I had just the very same problem and the propsed solution from @alexanderdd would be perfect. Is there any activity in this issue? How can it be reopend and pushed?

Thanks

So I expect the storage used by nextcloud server would similarly block the creation of such a long file name

solracsf commented 2 years ago

Well, on Windows, you can create such file. Error is produced when file is uploaded to Nextcloud.

It works on Linux too:

Exact file name is

touch 1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901.md

Same bug here. I can upload file with to long paths from windows but cant sync them on linux. I use cryptomator, so I can't find the corresponding files which are too long. Linux NC Client 3.5.4 Windows NC Client 3.4.1 Cryptomator Windows 1.6.5 (msi-3397) I attached the log file from the linux client. I hope there is no private data included, otherwise please delet the log-file after downloading it. 20221126_1240_owncloud.log.0.txt

just saying: This bug lead me to leave linux and nextcloud for quite some time and fall back to windows due to heavy work load.

Just run in to this error.

Dragged an image out of a web browser on to local drive in a folder that's managed by NC, and now getting the error. There doesn't appear to be any way to fix it at all.

Normally I can use old-school cmd prompt and do a dir /x to see the 8.3-style filename, and then delete that.

13/01/2023  06:51            23,881 HRB          HrbyFl0Q3AVOptlJJSnQ4AmZpBA0_UhiEDDvGTQZbvvrq_HLudeCzhZAqvGTVJ4C0yEvclEwqO-7790VldeqkAdJj38JKe-XSqx-BpLXwPbkKTuKNWg4lhoSr9zVjGQzynNxP2Y5aE5KRi9pEXQRVT4mc5OVM5TNjDVtJcHSZvHlD-otkaUgaQvN9-CaFF7eB9X8VLjKLBJ2gulmHaOKxfWyBn93_5wJzCQEEcRu_QpHXCEl5d4dcNVT9kJ.jpg

As you can see above, the 8.3 filename is just HRB, however del HRB does not work. I suspect this is becuase NC is holding on to the file until it syncs, but obviously it can't sync because name too long.

Anyone know of a way to delete the file that has too-long filename from an NC-managed folder on local disk? I'm on Windows 10.

Suggestion: Link on NC context menu, or the NC tray menu (where error is shown), to delete/rename the file.

EDIT: Found a workaround:

Go to folder with the problem file
Move all the non-broken things (incl. subfolders) in to a different folder
Delete the folder that cotnains the problem file

Hopefully this is of use to others running in to this problem on Win10 (:
