Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 12.0.2): 15.0.8
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): Apache 2.
PHP version (eg, 7.1): PHP 7

The issue you are facing:

In the nextcloud web interface, all files are listed as slightly smaller than they appear when synced to a computer or downloaded. For example, an image which appears to be 5.1MB on my desktop shows as 4.9MB on the web interface. A folder which appears to be 450.2MB appears as 429.2MB on the web interface.

Is this the first time you’ve seen this error? (Y/N): N

Steps to replicate it:

  1. Use web interface
  2. compare file sizes with files on local system

I’m guessing your local OS is showing you kilo/mega/giga, and NC/your server is using kibi/mebi/gibi (or vice versa). The file size is really the same, the two metrics are just slightly different.

I would think that too, but when I list the byte size of the file on disk, I get 5,199,450 bytes on disk & 5,268,848 bytes on Nextcloud.

Do you use server-side encryption, this increases the file size.
