File type not found

[Gary Killen]

I have a couple of files, not all of my files, that when I return to reopen the files will not open.  Mousing over them when opening them the popup says, "AFDESIGNER File," but when I open them it reads, "File type not supported."  I do not understand why Affinity Designer does not recognize it's own file.  Did I do something wrong?

Hi Gary, I opened this file in a hex editor and it was blank, a megabyte of zeroes. There's no information in it so Affinity doesn't recognize it as its own file. I'm unsure how it was created.

Perhaps by a failed attempt to save to somewhere other than local storage?

[Gary Killen]

Would you know if I did something wrong in saving it?  I created it in Affinity Designer and did a "save as."  I just do want to lose my work again making the same mistake.

Where did you ‘Save As…’ to? A local hard drive, or somewhere else? And if the latter, precisely where?

[Gary Killen]

I save to an external hard drive where other files are also stored.

To avoid losing your work in the future, ‘Save As…’ to a local hard drive and then backup to the external hard drive as a separate operation. The way the Affinity apps load and save their native files is highly efficient, but if you lose the connection to the target device during a save you can all too easily end up with a corrupted file.

Hard drive discs can just go bad, too.

Thank you KarinC for responding. It is an external hard drive.  It is working.  I have created other files in Designer since the lost ones and they are all accessible.  Other files from other programs are also accessible.  I have attached a png of one I created yesterday.  Do you think the file itself may have been to large?  What I was creating was a background to look like a rubber doormat.

They can get bad sectors and still work.

[Gary Killen]

I did not think about that.  I will run a check on that drive to see if there are bad sectors.   Thank you!
