The files with extension .gcm in the books directory are not your 
account files. They merely store some metadata like which tabs were open 
the last time you closed gnucash.

The actual books are where you chose to store them when you initially 
created and saved them. That's just like other applications such as Word 
work.

The file dropdown on the other hand maintains a list of the most 
recently used files (again like many applications do). If the entries in 
this list don't work anymore that can be because

1. you have moved/deleted the original files
2. they are using a backend that is no longer installed

So some relevant questions:

a. where did you originally save the account files you are now missing ?
b. what file format did you use to save them ? Sqlite, xml, postgresql, 
mysql ?
