Is there a file size limit for encrypting a single file with GnuPG(1.0.xx,2.0.xx,2.1.xx)?
The file size ranges from about 2GiB to 100GiB. I'm not worried about the 2Gib but I'm not really sure if it's a good idea to encrypt a single 100GiB file. Do I run into problems if I do that or is it perfectly safe to encrypt such large files?
I checked the FAQ on https://gnupg.org/ and only found an article dealing with
file size limits of the different ciphers but not if there is a limitation of the program itself. Here is the link to the specific part:

Kind regards
Probably you know this but I will make it clear for those who don't: GPG is documented either "symmetric" or "asymmetric" encryption. Actually the "asymmetric" encryption uses symmetric underneath, and only uses asymmetric to send/hide the symmetric encryption key. GPG allows specifying the "cipher" used for the symmetric encryption: "--cipher-algo" <- See the online manual [ gnupg.org/documentation/manpage.html ]. There is size limit for some ciphers as explained in YOUR line and grawity's answer. – Craig Hicks – 2018-04-30T22:02:25.297
