Afx 2017 on windows 10 is locking footage items on a hard drive making it impossible to change them by other programs.
on windows 7 Afx 2014 don't exhibit this behavior. Not sure if this is something to do with version of windows or AFx but definitely need a solution.
This ability is essential for any video or CGI pipeline. Files do need to be changed by other programs without closing Afx or creating new version of the footageas such workaround would slow work tremendously.
Adobe AE CC 2017 is a dog. Really stinks up the joint.
There are very few issues officially recognized as bugs, but there are a great many quirks in it that can make it virtually impossible for many people to use without long and painstaking diagnosis. Interestingly, some people report no problems... but if you look at the long list of woes reported in this forum, you'll probably come to the conclusion that something is amiss.
My advice: use an earlier version that actually WORKS.
I haven't seen this issue on my systems yet.
Can you describe a bit more what you're doing so I can try to recreate your process on my end and see if I can make it do the same thing?
