This happens in After Effects CC 2023 (but I think it does the same thing in After Effects CC 2022) using Windows 10 Pro. When I load After Effects I get the message "Your disc cache folder is on a drive that does not have enough available space to safely store the full amount specified in your preferences. Please make more space available or go to "Media & Disk Cache preferences to change the folder or maximum disc cache size." In think the above message is incorrect. Drive H, where disc cache is: After Effects disc cache folder takes up 1.45 TB (1,606,163,136,512 bytes) The drive says: used space 1.46 TB free space 2.17 TB Capacity 3.63 TB ----- Media & Disc Cache preferences say: Enabled Disc Cache: [checked] Max Disc Cache Size: 2500 GB Basically the "Your disc cache folder is on a drive that does not have enough available space..." message is wrong. The message doesn't take into account the amount already taken up by the existing After Effects disc cache. Since the drive has a capacity of 3.63 TB (and I mainly only use that drive for After Effects, and previously I only used it for the AE disc cache and it gave this error previously) I should be able to store roughly (or very close to) 3.63 TB of After Effects cache on it (if I didn't use it for anything else). But After Effects just seems to say (made up variables): "If free_space_on_drive < max_AE_disc_cache_size then show that "not enough space" warning. Surely what it should be saying is something like "If free_space_on_drive < (max_AE_disc_cache_size - the_current_AE_disc_cache_size) then show the "not enough space" warning. With the current way it does the warning, if you only use a drive for the AE disc cache, if you set the max disc cache size to > half the disc size then when half the disc is used up you're going to get the current warning incorrectly telling you there's not enough space to fully store the cache.
