Como posso filtrar o arquivo de texto para remover tudo e apenas deixar os caminhos nele? Por exemplo: 

dslkjcblasdjncklasdnlc /asdds/ads/adss/sdf.jpg asljdascuashn sdkm
/sdf/dsf/dsf/dfs/sdfs.txt ,nbaskhdnasm.ddslkjcblasdjncklasdnlc
/asdds/ads/adss/sdf.jpg asljdascuashn sdkm /sdf/dsf/dsf/dfs/sdfs.txt
,nbaskhdnasm.ddslkjcblasdjncklasdnlc /asdds/ads/adss/sdf.jpg
 asljdascuashn sdkm /34/34/dsf/dfs/sdfs.txt

como posso remover tudo e deixar apenas os caminhos para que eu tenha:

/asdds/ads/adss/sdf.jpg
