hm. i’ve been using FL Studio since version 4 in 2004, have uninstalled and reinstalled countless times and have never lost a project file. i’m wondering, though, because i also took pains to back my stuff up periodically and therefore i’m trying to remember if i ever had to rely on this.
if this happened, i don’t think it’s normal behavior. are you 100% sure all of your flp files are gone?
edit: i’m currently researching this on the image-line forums. saw a staff admin post something that tracks with my experience in a thread with a user having a similar issue; they updated, now they can’t see any of their projects.
FL Studio installations can’t delete files, they will be somewhere you left them.
so in your case you said you uninstalled first. i’m trying to remember if there’s a checkbox or something to remove user files during uninstallation, but i can’t remember.
at any rate, i am definitely curious about this. i am sort of gathering that this is already from awhile back, but i think something went specifically wrong in your case. maybe i should try backing my stuff up tonight and then uninstalling FLS and see what happens.
