Hard disk crashed? Accidentally formatted the wrong partition? Your kid played with your important files and now they are all gone?
HAVE NO FEAR. Squirrelman is here to help with this pack of highly useful file recovery programs. All are "portable" runtime versions, which means you don't have to install them, just run them.

This pack includes the following :

GetDataBack for NTFS 4.0
R-Studio Network Edition 4.0
File Scavenger 3.2
Migo Recover Lost Data 3.1.1.2C
Multistage Recovery 3.6
RecoverMyFiles 3.8
Advanced Photo Recovery 2.1
CDRoller 8.50
PC Tools File Recover 7.5.0.10
Power Data Recovery 4.60
Ontrack Easy Recovery 6.12

They have saved my butt on several occasions. If you can't find your files with one, try the next one. One of these should be able to recover your files. I cannot guarantee 100% success but with these apps, your chances of recovery are extremely high, and if these all fail, your files can only be recovered by hardware based recovery companies that charge big bucks.
