How is your script waiting for up to 4 hours? Could that not have a section where the time has exceeded the limit and it fires an alert?
Alternatives might be to have your main script write a message in a log file that you alerting script can read 4 hours (and a little bit) after the main script is called in. This could be via a separate cron job or by you main script sending this in at the beginning:-
A few more questions:-
What have you tried so far?
What would you expect you main script to do if the file has not arrived?
If it is a large file, how do you check that the file is complete before you start processing it?
What output/errors do you get?
What OS and version are you using?
What are your preferred tools? (C, shell, perl, awk, etc.)
What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?
There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.

LEARN ABOUT NETBSD
crontab
CRONTAB(1) BSD General Commands Manual CRONTAB(1)NAME
crontab -- maintain crontab files for individual users (ISC Cron V4.1)
SYNOPSIS
crontab [-u user]
crontab [-elr]
DESCRIPTION
crontab is the program used to install, deinstall, or list the tables used to drive the cron(8) daemon in ISC Cron. Each user can have their
own crontab, and though these are files in /var/cron, they are not intended to be edited directly.
If the /var/cron/allow file exists, then you must be listed therein in order to be allowed to use this command. If the /var/cron/allow file
does not exist but the /var/cron/deny file does exist, then you must not be listed in the /var/cron/deny file in order to use this command.
If neither of these files exists, depending on the compiled in settings, only the super user will be allowed to use this command, or everyone
will be allowed to use this command. On NetBSD everyone is allowed to use this command.
The default maximum size for a crontab is 256 kilobytes, but this may be changed for all users on the system by putting the desired maximum
size (in bytes) in the /var/cron/maxtabsize file.
If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines
``your'' crontab, i.e., the crontab of the person executing the command. Note that su(1) can confuse crontab and that if you are running
inside of su(1) you should always use the -u option for safety's sake.
The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is given.
The -l option causes the current crontab to be displayed on standard output.
The -r option causes the current crontab to be removed.
The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit
from the editor, the modified crontab will be installed automatically.
FILES
/var/cron/allow Optional list of users that are allowed to use crontab.
/var/cron/deny Optional list of users that are disallowed to use crontab.
/var/cron/maxtabsize Maximum size of crontab files. Defaults to 256 kilobytes.
/var/cron/tabs/ Directory containing the individual user crontab files, named after the user.
DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line.
SEE ALSO crontab(5), cron(8)STANDARDS
The crontab command conforms to IEEE Std 1003.2 (``POSIX.2''). This new command syntax differs from previous versions of Vixie Cron, as well
as from the classic Version 3 AT&T UNIX syntax.
