Make a list of files in the directory, using opendir() and readdir().
The results will come in no particular order.

There is no guaranteed way you can tell "when a file came to the folder".
You can get close with st_mtime or st_ctime from stat() on each file.

Sort the files by time.  Perhaps this is an in-memory sort with qsort().

I don't know what you mean by "read 100 files at a time".  Open 100
files, read a byte from each, repeat reading the next byte from
each file until end-of-file?

Here is how you can list n oldest files

ls -lrt <directory>/<file extensions> | grep -v total | awk -F " "
'{print $9}' | head -100

this will list 100 oldest files of particular extension in a given
directory

You will if you can,
You won't if you can't

Or something like:

ls -F1t | grep -v '[*@/=]$' | head -100

ouch.  Getting the *next*, an n*100th, files will be a neat trick from here.
