Because of a problem in an XP computer I had to use Ubuntu Live CD to access and save data to an external USB drive. Now, some of the folders in the USB can be accessed without any problem but some of them not. Any file in this folder starts with "locked-" and ends with a strange extension.

The output of ls command is:

-rw------- 1 paco paco  19968 may 19 19:02 locked-Xiquets.doc.riwd

I have tried to just remove the .XXXX extension but then LibreOffice can't properly open files. It asks for encoding but ISO-8859 and UTF8 give error in opening the file.

Any idea? Thanks in advance.

Output of mount:

/dev/sdb1 on /media/48C1DA7909338E77 type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096)

Renaming JPG files does not work:

paco@xubasco:/media/48C1DA7909338E77/papa/FOTOGRAFIA/CUADROS$ mv locked-CUADROS_120.JPG.fpyq CUADROS_120.JPG
paco@xubasco:/media/48C1DA7909338E77/papa/FOTOGRAFIA/CUADROS$ display CUADROS_120.JPG
display: Not a JPEG file: starts with 0x60 0x32 `CUADROS_120.JPG' @ error/jpeg.c/EmitMessage/236.

Output of lsattr:

paco@xubasco:/media/48C1DA7909338E77/papa/FOTOGRAFIA/CUADROS$ lsattr locked-CUADROS_090.JPG.gfml
lsattr: Not implemented function while reading flags on locked-CUADROS_090.JPG.gfml

I had to translate from Spanish, sorry.

What was the issue you were having on the XP computer, and what tools did you use to recover the files? Were these files "locked" when on the XP drive, or did it happen when they were moved to the external hard drive? My guess is that this has something to do with what broke your XP box, but I am unsure. – reverendj1 May 23 '12 at 17:18
Hi, the issue with the XP computer (not actually mine) is a known trojan that blocks access to the computer. I am asking for help to remove it to the antivirus program help forum but it is not easy. It only actually shows a screen where you are asked to pay to unlock your computer. To save data I have just started Ubuntu and saved to the hard drive. All folders copied are in the computer data partition, supposedly the trojan is in windows start, not in data partition. – pacomet May 23 '12 at 17:24
Another curious thing is that in the photo folder some subfolders show pictures (jpg) without any problem and some others also show "locked files". Maybe I have to separately save the different folders to keep data safe? – pacomet May 23 '12 at 17:25
If you rename the "locked" .jpg files, can you open those? Maybe libreoffice just can't open those .docs, because you need a language pack or something. My best guess is that the Trojan didn't really do anything but rename all the files to try and get you to pay. – reverendj1 May 23 '12 at 17:30
What is the output to mount? Please add the output to your question and if possible point out which line is the drive with the problematic files on it. Also add the output for lsattr from the files in the directory. – jippie May 23 '12 at 17:32

There was not an Ubuntu based solution. The problem came from a virus in the computer. The only solution was to use some tools from the antivirus supplier that didn't perform exactly as needed. Not a good solution but a solution.
