Hey Vladut:
If you succeed in recovering the previous *dbf* file, you can join it again
to the recent damaged shapefile, by the common field of area, provided your
previous field SUP (area) was actually the area of the geometry elements.
Before joining, recalculate and/or round the area fields,
This is a great idea if she is on Windows.
Right click on the folder and select previous versions.
Then just selectively drag and drop files from that
restored folder.
Backups - backups. At home I have no fewer than
6 backups around me. Even on the road I have 2 - 3
backups with me at all
Restoring only the dbf will do am error for a shapefile because it is sync
with shp and shx.
The retrieve should fo for all three files or nothing.
The dhx could be recalculate from dbf and shp. But dbf and shp must be
sync-ed.

Windows has a feature called previous versions. Locate the shape files on
explorer, look for the dbf file, right click, properties and see if you
have any previous versions that you can restore.

Ciao Vladut,
I'm sorry, you have no chanches to recover deleted attributes.
You need to populate attributes again.
However, in my mind, this could be not a impossible job.
SUP (area) attribute is a geometry dependant value, you could calculate
areas again with a simple string in field
If you made changes to the tables and saved them then there is for me no
obvious way to recover the information to its previous state.
Unless you had a backup of your original data which is always a good
thing to have.
Good luck.

Hi,
I used MMQGIS to delete duplicate geometries. After deleting, I saved the file
using a pre-existing name, overwrote the file and opened it.
The file was blank. What could have gone wrong? I have lost all the
data/records in the old file. The attribute table was blank and the file fise
1kb.
