AEJuice Find Missing Files is a script for After Effects that relinks missing files in a single click. When files in a project go missing, you select a folder where they might be located, and the script searches through that folder automatically and relinks the missing files it finds.
Search time depends on how many files sit in the folder — the more files there are, the longer the search takes. For that reason it works best when you point it at the folder where the missing files are most likely to be located, rather than a large folder that takes longer to scan. The script is also integrated with kBar.
AEJuice Find Missing Files supports After Effects CC 2015, 2017, 2018, 2019, 2020, 2021, 2022 and higher. It was last updated in October 2023 and is listed here as free; check the developer's page for current licensing details.
