Whoever owns those files is the person who copied them.

You can copy files for example, by using an editor incorrectly, or misusing the mv statement. It's not hard to inadvertantly overwrite a file.

Plus, it sounds like protections aren't what the should be.
If you and pqrs are in the same group, protections on pqrs' home directory need to be changed. If you aren't in the same group, it means his home directory (or yours) is open to the world. Probably not cool.

If you need to share files, use /tmp - or create a standard exchange subdirectory for each user - that has group read/write permissions so everyone can copy & read files in the directory.

There is no real audit trail for file activity. The only thing you can do is to stop it from happening again.

SYNTAX

       pure-quotacheck -u username/gid -d home directory [-g group/gid]

DESCRIPTION

       pure-quotacheck create a .ftpquota file in the specified directory.
       This file contains the current file and size of the directory, and it is used by Pure-FTPd when virtual quotas are enabled.
       It's recommended to periodically run pure-quotacheck for every user, in crontabs.

OPTIONS

       -d <directory>
	      Scans the specified <directory>.

       -g <group or gid>
	      Sets the group files will be scanned as. This is optional : if a user name is passed to -u</fR>, group are automatically retrieved.

       -u <user or uid>
	      Set the user name files will be scanned as. This is mandatory, and it can't be "root".

AUTHORS

       Frank DENIS <j at pureftpd dot org>

SECURITY

       pure-quotacheck switches real and effective uids/gids as soon as possible. Root privileges are never given back.
       pure-quotacheck refuses to scan directories with uid = 0 (root) or gid = 0 (wheel/root) .
       pure-quotacheck performs a chroot() call to the home directory. It never traverses parent directories.
       pure-quotacheck only scans real files (no socket, no pipe, etc) .
       pure-quotacheck enforces read access on directories to prevent against people doing chmod 0 before a quota scan.
       pure-quotacheck enforces write access on the home directory to properly write the .ftpquota file.
       pure-quotacheck never scans the same inode/device pair twice.
