Facing issues with file deletion from storage

The file upload is working just fine. I am using Appwrite SDK 14.0.0, I had to use an earlier version due to some other issue. Thanks.

Do you have permission set to delete such file?

Permissions as in, settings > permissions?

Yes

That affects all the files in storage

Except if the permissions are file-level

Sorry if i sound noob, but does file-level mean?

Also am I doing something wrong?, the file upload works just fine

Collection or bucket level permissions affect all the files inside such collection or bucket.

File/document level permissions affect only to some specific files/documents, so meanwhile you can modify and delete some docs, you will not be able to do the same with others
