I was working on a file at office and everything was ok, after opening it at home a message popped up The file appears to be corrupted.

PS. since I bought the programs a few years ago there was never a problem, and in the last few months it has happened to me a few times

Pendrive

So an via USB connected external storage device, which might fall into power saving sleep mode when not directly used/accessed for some time. - Every external connected device, no matter if an USB-stick or USB-drive, network NAS, network cloud drive etc. can make trouble here, when using the Affinity software products to directly store and/or read data from those external devices.

Thus a rule of thumb when using Affinity software is always, to better work I/O wise only on the local drive/disk with the Affinity software in order to prevent possible data lost and to use all external storages just as (like) a backup storage (drive). Meaning to manually copy files between the local working drive and external backup storage via system level file copy/move operations, before opening them in Affinity, instead of accessing external stored files directly from inside of an Affinity product.
