Howto recover files / Howto remove duplicate files

 My first micro (16gb) sd card died after years of work in a spare phone. Windows couldnt read it anymore and I had no device with a *real* os near but, at https://www.cgsecurity.org/wiki/PhotoRec I found everthing I needed. Worked flawless.

 
 
You will not recover your direcotry hirachy and some files get duplicated. So next step is to get rid of tem:

With the powershell one liner:

ls *.txt -recurse | get-filehash | group -property hash | where { $_.count -gt 1 } | % { $_.group | select -skip 1 } | del

ls *.txt -recurse | get-filehash | group -property hash | where { $_.count -gt 1 } | % { $_.group | select -skip 1 } | del

view raw removeDuplicateFiles hosted with ❤ by GitHub

you can drop every file got duplicated.
