While I was working on pset4/recover I couldn't make it work as desired, so I wanted to check the first few bytes of card.raw manually. I double-clicked the file and now my cs50 IDE never loads and crashes the browser.

Is there any way to fix this? Thanks

The IDE isn't able to recognize the card.raw file as something that can be opened as any particular file type. When I double-click on it, the IDE hangs, as you experienced. My browser didn't crash (Firefox), it gave me a popup error message after it timed out. Yours may have actually crashed, I can't explain that.

However, if you right click on the file name and select "Open as hexadecimal" from the popup menu, you should get what you want. If not, leave a comment.

Hope this helps. ;-)

    Hi, indeed the browser did not crash but it was the IDE, same as you. I did not know the "Open as hex" option, so thanks.
