PhotoRec to parse from a ZLIB Stream

#1 Post by GreySlater »

Hello together

as PhotoRec can't parse directly from a "broken" Acronis Backup TIB archive file I was able to "convert" my TIB file into a ZLIB stream file.
  • what's my best option with this ZLIB stream file in the first place to ensure PhotoRec can get the most out of it
I highly want to appreciate the effort of work done in PhotoRec and it's file type recognition - this said I could carve out the ZLIB stream with foremost but I'm missing the ability to get "correct" and working files when working only with the option to identify a file by its header

Thank you

PhotoRec doesn't work on stream. You have to decompress the stream (zlib-flate -uncompress), create a file with the output and run photorec on this file.

Thank you @cgrenier

I decompressed everything into one file but was not sure which file extension I should use. I went with RAW

For comparison I made this with a "good" TIB archive were I backed up multiple known files (GIF, JPG, PNG, SNT, SQLITE, PDF) but qphotorec_win.exe has a hard time finding only one PDF and one GIF

how can I help PhotoRec
