Please help me to restore my file, I saved it but my computer cant find it

Hi all, I made an file with all my household spendings with Libre Office Calc, I saved it and every time I worked on it I saved it again as this is a very precious file to me. Now I cant seem it anymore and futhermore I cant seem to find it on my computer. I am 100% certain I saved it even though I cant find it anymore. Do you have any advice or recommendations for me on how to get my file back? Thank you very much for your time and effort.

best regards,

If you open the LO Start Center, go to File / Recent documents and see if it’s listed there. Otherwise you can do a file system search using the file manager or a utility.
