Automatically Deleting Files After X Days - General Data Protection Regulation May 2018

Hello Greg,

Was there any progress on that?

Thanks,

Luk

So created a quick bit of code to delete files older than X days but its very rough and hasn't been tested properly.  It doesn't get round the issue of dates of folders, nor does it get round the issue of not knowing the creation date.  Comments welcomed as there must be a better way than this?

   enum MODIFIED_DATE_TYPE {
        SERVER_MODIFIED_DATE, CLIENT_MODIFIED_DATE;
    }

    private long deleteFilesOlderThanXDays(long numDays, MODIFIED_DATE_TYPE TYPE) throws DbxException {
        //ALPHA - add protection against going above long.MAXIMUM
        long numberFilesDeleted = 0;
        ListFolderBuilder listFolderBuilder = client.files().listFolderBuilder("");
        ListFolderResult result = listFolderBuilder.withRecursive(true).start();

        while (!result.getHasMore()) {
            if (result != null) {
                for (Metadata entry : result.getEntries()) {
//                    System.out.println("Analysing: " + entry.getPathLower());
                    if (entry instanceof FileMetadata) {
                        Date dateOfFile;
                        switch (TYPE) {
                            case CLIENT_MODIFIED_DATE:
                                dateOfFile = ((FileMetadata) entry).getServerModified();
                                break;

                            case SERVER_MODIFIED_DATE:
                                dateOfFile = ((FileMetadata) entry).getClientModified();
                                break;
                            default:
                                throw new AssertionError();
                        }
                        //Check to see if the current file is too old
                        if (getDaysBetween(new Date(), dateOfFile) > numDays) {
                            this.deleteFile(entry.getPathLower());
                            numberFilesDeleted++;
                        }
                    }
                }
                if (!result.getHasMore()) {
                    return numberFilesDeleted;
                }
                try {
                    result = client.files().listFolderContinue(result.getCursor());
                } catch (DbxException e) {
                    //ALPHA - TIDY UP HERE.  CATCHING or THROWING??? - GDPR - Note what you're logging
                    //  log.info("Could NOT get listFolderContinue");
                }
            }
        }
        return numberFilesDeleted;
    }

tuancrab Thanks for the feedback. Dropbox doesn't offer a feature exactly like this, but I've sent this along as a feature request.
