I purchased a page of arrows from Adobe Stock. I tried to open the file in Preview and a pop up box opens up and says that the file is unsafe. I tried a few other files in Adobe Stock and it does the same thing. What program should I use to open the file I purchased and take the arrows I want off?
Is it a vector file? In that case, Illustrator.
Not sure? Post the ID number and we can check.
They are vector arrows, and at the bottom the format is AI (Adobe Illustrator):
Ideally, you want to work with them in Illustrator so that you can size them up or down with out degradation. You can open them in Photoshop but they will rasterize (covert to pixels), so you will need to pay attention to the resolution and scaling.
