There is no "create time" value, unfortunately.

There is only access time, change time and modification time.

To use the modification time you could do:

find /folder/name -maxdepth 1 -type f -mtime +30 -print0 | xargs -0 rm

The above will not recurse into subdirectories. If recursion is desired omit "maxdepth 1"

woolmilkporc: "There is only access time, change time and modification time."

These files are never modified or changed since they are voicemail messages in WAV format on the server.  The script will be run as a daily cron job that will check folders and auto clean up messages which were left more than 30 days ago.  In this case the change time and modification time would actually be the same as the create time.

Also no need for recursively since there are no folders in the directory we are looking in.

OK then,

use mtime, and there is no difference between using maxdepth and not using it if there are no subdirectories.

You could try

find /folder/name -maxdepth 1 -type f -mtime +30 -print0 | xargs -0 echo rm

to have the "rm" statement(s) just printed, not executed - kind of a "dry run".
