Yes, they are pooled in the same way as regular files.

Re: [BackupPC-users] Question about attrib file structure - Help needed
Was hoping to get answers to these question to confirm the algorithm I am using on my BackupPC_deleteFile script. I just want to make sure I am not missing any subtleties here with the attrib files.

[BackupPC-users] Question about attrib file structure
Is the following true: 1. If a directory is *empty*, is there any reason for it to have an attrib file? Because in playing around with creating and deleting directory contents, I found that sometimes even after emptying directory contents, the subsequent incremental backups may sometimes still have (empty) attrib files. 2. If not, can I safely erase any (empty) attrib file that has no files associated with it? 3. Other than type=10 (delete), is there *any* reason for an attrib file to contain an entry for a file that is not present in the directory? Because, I have found some attrib files on my system in past backups that have file entries with type 0 (i.e *not* type 10) yet there is no file present in the directory. 4. If not, can I safely *remove* any non type=10 attrib entry if the corresponding file is not in the directory?
