Hi there. I have posted before and even got a tech to look at the problem, but no joy, so hoping the community can help. I scan images using an Epson graphic arts scanner. The images are 48 bit depth, uncompressed TIFs, typically about 1 GB off the scanner. I edit in Affinity and have done so through both Version 1 and 2. FIRST: my latest image, same parameters as described, has caused Affinity to choke twice, as I near completion in editing (which takes WEEKS). The file tries to load, and then I get a message that reads "failed to load document, document appears corrupted" Here is the response I got: "Hi Sandra, I just wanted to let you know that I've downloaded your file. It also fails to open for me, so I've logged it with our developers to see if anything can be done. However I can't give any timeframe as to when this may be. In reference to your other post and files getting larger, when this occurs try using File > Save As to create a new file. As this process should get rid of anything not being used and streamline the file." So I started editing it again, and again, near completion, Affinity has choked. I have a Dell Precision laptop, 32 gigs RAM, 2.57Ghz processor. There is no reason that affinity should be choking on this. I have worked on scores of similar images. SECOND: (and alluded to in tech response above): the uncompressed TIFs come off the scanner at just under a GB. But as I work, the image bloats to 5 or 6 GB. I tried the advice above, of saving iterations under different names, but they are ALL bloated. Why does this happen? I thought maybe all the history was saved with every edit, but not so. I don't work in layers either - the document is flattened. I do need to routinely zoom to 400% for editing (painting in a true black back ground with the clone tool, using a WACOM tablet and stylus). So. Any advice? Now Affinity got bought by Canva, let's hope it doesn't do a Boeing. Please advice why current version of Affinity chokes on large files, and how to stop the constant bloat in size. TIA.

I am new to editing software so I hope someone can help me. I am generating enormous files as I try to edit my work in Affinity Photo. Some files are hundreds of megabytes and one file has reached 2.3 gigabytes in size. I have been creating layers, adjustment layers and generally experimenting some of the time. But I have also been deleting layers and cleaning up as I went. I thought this would help to contain the file sizes. I read online somewhere that the history channel can contribute to this? Can I turn this off permanently? My question is 1. Why am I generating such huge files and how can I avoid this? 2. How can I reduce the file sizes to manageable proportions- bearing in mind that I have spent a lot of work on some of them and I don't want to do this all over again.I intend printing these files via an online printing firm. 3. Why is there no comprehensive book in English when there seems to be a German equivalent? If there is anyone who can point me in the right direction I would be very grateful. I've tried to upload some photos for members to view but both uploads have failed -probably due to the huge file size!
