 Extract localizable texts to locres or txt file:  
 `UE4TextExtractor.exe <path to folder with extracted from pak files> <path to texts.locres file> [-old] [-raw-text-signatures=<signature1>,<signature2>,...] [-all-uexps]`  
-`UE4TextExtractor.exe <path to folder with extracted from pak files> <path to texts.txt file> [-raw-text-signatures=<signature1>,<signature2>,...] [-all-uexps]`  
+`UE4TextExtractor.exe <path to folder with extracted from pak files> <path to texts.txt file> [-raw-text-signatures=<signature1>,<signature2>,...] [-all-uexps] [-src]`  
 Example: `UE4TextExtractor.exe "C:\MyGame\Content\Paks\unpacked" "C:\MyGame\Content\Paks\texts.locres"`  
 
 Use `-raw-text-signatures=<signature1>,<signature2>,...` (or `-raw-text-signatures=all` if you don't want to go into detail, but it's not recommended) modifier for parsing localizable text by custom signatures. See also: [here](https://github.com/VD42/UE4TextExtractor/blob/master/RAW_TEXT_SIGNATURES.md).  
 Use `-all-uexps` modifier for additionaly parsing uexp files without matching uasset or umap files.  
+Use `-src` modifier to add string source information (filenames) to the txt file.  
 
 Convert locres to txt or backward:  
 `UE4TextExtractor.exe <path to texts.txt file> <path to texts.locres file> [-old]`
