When saving .ai data in NAS using Adobe Illsutarator 2021.app, there is a high probability that a file like [Acr535752510473602701316.tmp] will be generated in the same folder, and even if you try to delete it, it cannot be deleted (time passes). Can be deleted). I tried dropping the version of Illsutarator several times, but the result is the same. A NAS supporter told me it was a bug in Adobe Illustrator. No such file was generated when saved to the Mac desktop instead of the NAS. What is the cause?
