Hi newbie_01,

I don't know about such custom applications, so, a custom script could be adapted to do the job.

As you can see below, for this tasks "find" command would be your friend, and combining it with desired
criterias and some other commands, you'll satisfy your requirements.

You've asked for:

1-) removing files that are x-number of days old,
Code:
# 1-) Looking for txt files older than 365 days and printing them within folder and subfolder
 find . -name "*.txt" -mtime +365

# 2-) Printing txt files modified less than 365 days ago within folder and subfolders
 find . -name "*.txt" -mtime -365

# 3-) Printing txt files modified 365 days ago within folder and subfolders
 find . -name "*.txt" -mtime 365

# 4-) Removing txt files older than 365 days within folder and subfolders
*(if you want to remove files is advisable to be sure about files listed/found by "find...")
 find . -name "*.txt" -mtime +365 -exec /bin/rm -f '{}' +

About -mtime: (-mtime n)
(+) means greater than, (-) means less than, and without any symbol means exactly equal to.

2-) Zipping files "if they are core dumped files"
*(Below examples how to zip files, but which is the characteristic of a core dumped file?)
Code:
#1-) Looking all txt files within folders and its subfolders and compress them in a unique zipped file (Compressed_Files.zip)
 find . -name "*.txt" -print | zip Compressed_Files -@

# 2--)Compressing each txt file within folder and subfolders file, adds to original name ".gz" (filename.txt to filename.txt.gz) 
# and deletes original file
 find . -name "*.txt" -exec gzip -f '{}' +

# 3-)Unzipping each txt files within folder and its subfolders, deleting original gz file.
 find . -name "*.txt.gz" -exec gunzip -f '{}' +

3-) Removing files if they are zero-sized files:
Code:
 # 1-) Removing zero size files within folder and its subfolders.
1-) find . -type f -size 0 -exec /bin/rm -f '{}' +
or
2-) find . -type f -empty -exec /bin/rm -f '{}' +

Hope it helps,

Regards.
