How can I revover a backup file into portfolio performance, the extension is backup and i don´t see any option for this.
Just rename it; or better, make a copy first in case you need to try again.
But the extension is .backup
I rename it to xml but doesnt work, may be corrupted?
The file extension depends on various conditions as you could store the file in plain format, compressed or encrypted. The possible extensions are .xml;.zip;*.portfolio
