For recovering deleted files from memory card or hardisks,pendrive there are a lots of software on internet but i recoment pandora recovery tool its free and easy to use.
How does it work?
Pandora Recovery allows you to find and recover recoverable deleted files from NTFS and FAT-formatted volumes, regardless of their type - you can recover pictures, songs, movies or documents. Pandora Recovery will scan your hard drive and build an index of existing and deleted files and directories (folders) on any logical drive of your computer with supported file format. Once the scanning is complete you have full control over which files to recover and what destination to recover them to. You can BROWSE the hierarchy of existing and deleted files, or you can use SEARCH functionality to find a deleted file if you remember at least one of the following:
- file size,
- file creation date, or
- file last accessed date
On top of that, Pandora Recovery allows you to preview deleted files of certain type (images and text files) without performing recovery. This feature becomes really important if you are forced to recover deleted files to the same drive. Currently you can preview files having several image file types (BMP, GIF, JPG, PNG, ICO,TIF, TGA, PCX, WBMP, WMF, JP2, J2K, JBG, JPC, PGX, PNM, RAS, CUR) and several text file types (TXT, LOG, INI, BAT, RTF, XML, CSS). Quick Viewer allows you preview file contents as text if it cannot find appropriate viewer for it. To use quick viewer you can select deleted file and or click the Quick Viewer icon or right click on deleted file and select ‘Quick View’. Quick View will then display a preview of deleted file.
