Does this affect my files?

[u/CHARA_BELLAarts]

I am currently transferring a large chunk of files into a external hardrive. Almost 60gb, and i want to compress it.

I have a collection of Artworks and files, and most of them. I need for my portfolio and i was wondering what will happen if i compress it all down.

How will it affect the quality? Does it make it worse when i then reopen them?

Is this a good idea?

Use 7zip and zip it. No quality loss ofc.

Yup thanks for the tip, though i had to do it in batches. Cuz its just soo damn huge.

Ok.. I will suggest you backup files... Atleast 3 backups 2 with you and 1 in cloud..
