My Nextcloud is in a OVH server
I can’t reach Nexcloud , I thing it’s because my disk is full
so, via putty I want delete files
Can I delete files in var/www/nextcloud/data/myname/files_trashbin ?
If I delete a file in /var/www/nextcloud/data/myname/files#
when nextcloud will be ok again, does this flies will be deleted in synchronised computers ?
Why do you not use the the normal trashbin function in Nextcloud?
You must execute:
sudo -u www-data /var/www/nextcloud/occ files:scan --all
(maybe another user name or path, documentation)
→ please delete files direct in Nextcloud and then in trashbin.
Maybe you find old update-backups in /var/www/nextcloud/data/updater-****/backups. You can delete them if you have got a backup of your Nextcloud.
Search also big files with ncdu
Because I can’t anymore go to the web interface.
I think Nexcloud is not able to work because 0 octets free on the disk.
Ok. Then delete manually and use the occ files:scan --all command. Maybe first use the command to check the command works for you. 
thanks for your answer
In putty, if I write the command
occ files:scan --all
the answer is
Command ‘occ’ not found, but there are 21 similar ones.
It has to be installed ?
Sorry you need php in the command. My fault:
sudo -u www-data php /var/www/nextcloud/occ files:scan --all
You can go to the directory.
Maybe you must use sudo with another user e.g. www-data (see above) or direct without sudo -u www-data e.g.:
php occ files:scan --all
Obviousely my database did not start

Sorry i can not really help. Maybe you can read some other occ-commands and execute them e.g. to find out if Nextcloud works, … List users, list apps, repair, … Please post the command and the error and not only the error. Thanks.
Using the occ command — Nextcloud latest Administration Manual latest documentation
Sorry, the command was exactly your’s. In putty.
sudo -u www-data php /var/www/nextcloud/occ files:scan --all
Maybe the database is not running. Delete some files and then restart the database or boot the system.
Thanks
I deleted some files and now I can open Nextcloud. I will have to dilete others files.
I will have to find how I can delete old versions of the files. Do you know ?
You can find the files in /path/to/nextcloud/data/username/files_versions I do not know if it is a good idea or not. First check with ncdu if there are huge files in this directory. Also you can change the settions for versions read this.
