Gnucash backends

2018-03-20 Thread Jonathan Silvey
I have been using GnuCash on Linux Mint for several years. As they were
getting full, I decided to start a new file and this has been running
successfully for three weeks. When I try to run the old data, the relevant
files are there but when I click on them, I get 'No suitable back-end found
 ...'

  I can't find out on Google what a backend is and I don't know how to load
a
 file. Can you help, please?

You must have made some other change in addition to using a new filename
when you started your new file.

No suitable  back end error usually means that the data file is not in the
expected format.  Gnucash expects an xml-like format or certain database
formats.  Database formats need corresponding database programs to read
them.

Read the FAQ about files for more info.

If this doesn't help come back with more details about the file format you
thought you were using, whether you are storing files in a different folder
and anything else that may seem significant.

That error may mean you are trying to open a file that is not a
gnucash accounts file.
What is the name of the file you are trying to open?  It will normally
be something.gnucash

Define a little more what you are doing (that didn't work). Did you?
1) Click on the object (and got that message)
or
2) Having started gnucash, used file=>open to try to open the file by 
name (and got that message)


The former might just be no association (what did you rename the old 
file to? what "file extension" is part of the name?)
The latter would imply something wrong with the file (it should work 
even without an association)
