-/**
- * In case encryption was not enabled, we accidentally set encrypted = 1 for
- * files inside mount points, since 8.1.0. This breaks opening the files in
- * 8.1.1 because we fixed the code that checks if a file is encrypted.
- * In order to fix the file, we need to reset the flag of the file. However,
- * the flag might be set because the file is in fact encrypted because it was
- * uploaded at a time where encryption was enabled.
- *
- * So we can only do this when:
- * - Current version of ownCloud before the update is 8.1.0 or 8.2.0.(0-2)
- * - Encryption is disabled
- * - files_encryption is not known in the app config
- *
- * If the first two are not the case, we are save. However, if files_encryption
- * values exist in the config, we might have a false negative here.
- * Now if there is no file with unencrypted size greater 0, that means there are
- * no files that are still encrypted with "files_encryption" encryption. So we
- * can also safely reset the flag here.
- *
- * If this is not the case, we go with "better save then sorry" and don't change
- * the flag but write a message to the ownCloud log file.
