The cp command does not work for directories with large number of files in them. I don't know what the upper limit is; I could probably find out with a lot of research. Also, the mv and rm commands do not work either under the same circumstance.
It has nothing to do with the rm command. The limit is the size of the buffer that commandline parameters can be fit into. This applies to all commands(except certain shell builtins in certain shells).

I suspect that the upper limit of the number of files that it can work on is 65536. I know that it is greater than 10,000 and less than 100,000. The 65536 is a SWAG number based on 26 years of Unix shell-scripting experience.
It is a "swag number" because it's a power of two, which memory is often allocated based on. It's the maximum size of the buffer for commandline arguments per process, and system-dependent.

I cleaned up the filesystem by removing files. I had to use a for-do-done loop and remove only one file at a time; this took many hours.
You may have been interested in the xargs command. It converts things read on stdin into commandline arguments, spanning across as many executions as necessary.

The tar syntax I quoted is in the man page on my AIX box. I've been using something similar to it for more than 20 years. It works.
It works in certain situations, yes. It will probably do what the OP wants. I have my doubts that "$FILESPEC" is working the way you think it is though -- either that or AIX has a very strange implementation of tar...

refile
refile(1) General Commands Manual refile(1)NAME
refile - file message in other folders (only available within the message handling system, mh)
SYNOPSIS
refile [msgs] [+folder] [options]
OPTIONS
Refiles the draft message, or the current message in your +drafts folder, if you have one set up. You cannot give a msgs argument when you
use this option. Moves a file into a folder. This option takes a file from its directory and places it in the named folder, as the next
message in the folder. The file must be formatted as a legal mail message. This means that the message must have the minimum header fields
separated from the body of the message by a blank line or a line of dashes. Prints a list of the valid options to this command. Keeps a
copy of the message in the source folder. Normally, refile removes the messages from the original folder when it refiles them. The -link
option keeps a copy in the original folder, as well as filing a copy in the new folder. Preserves the number of a message in the new
folder. Normally, when a message is refiled in to another folder, it is set to the next available number in that folder. The -preserve
option keeps the number of the message the same in the new folder as it had been in the old.
You cannot have two messages with the same number in one folder, so you should use this option with care. Specifies the source
folder to take messages from. Normally, messages are refiled from the current folder into another folder. However, you can take mes-
sages from a different folder by using the -src +folder option to specify the alternative source folder.
DESCRIPTION
Use the refile command to move the specified message from the current folder to another folder. You can refile messages in more than one
folder by giving multiple folder names as arguments.
If you do not specify a message, the current message is refiled. You can refile a message other than the current message by giving its num-
ber as a msgs argument. You can also refile more than one message at a time by specifying more than one message number, or a range of mes-
sage numbers, or a message sequence. See mark(1) for more information on sequences.
The current folder remains the same unless the -src option is specified; in that case, the source folder becomes current. Normally, the
last message specified becomes the current message. However, if the -link option is used, the current message is not changed.
If the Previous-Sequence: entry is set in the file, in addition to defining the named sequences from the source folder, refile will also
define those sequences for the destination folders. See mh_profile(4) for information concerning the previous sequence.
PROFILE COMPONENTS
Path: To determine your Mail directory
Folder-Protect: To set protections when creating a new folder
rmmproc: Program to delete the message
EXAMPLES
The following example refiles messages 3 and 5 in the folder +records: % refile 3 5 +records The next example files the current message
into two folders: % refile +jones +map The next example takes message 13 in the current folder and refiles it in the +test folder. The mes-
sage remains in the current folder as well as appearing in the +test folder. % refile -link 13 +test The next example takes a message from
the folder +test when it is not the current folder, and places it in the folder +outbox: % refile 3 -src +test +outbox
FILES
The user profile.
