help finding files

>previously paid for an account and don't anymore

As far as I know you have a limited time after you stop paying before your cloud files are deleted... I don't know the time limit, because I don't store anything in the cloud

This won't help the original person with lost files, but For anyone else reading this...
You should always have an extra copy of all files (or TWO full copies)
Computer crashes happen, so use an external drive for copies
A USB flash drive to keep in a safe place... here are 2, there are many more available
