<Overview>
Fast content search across large numbers of files.
Performs keyword and regular-expression searches over text files, Office documents (Word/Excel/PowerPoint), and PDFs under the specified folder, and can also search DICOM patient metadata.
For forensic use, MD5 and SHA-256 digests can be added to the result list.
File format is detected from the file's internal contents rather than its extension, so confidential documents disguised as backup files are still picked up.
<Features>
• Supported formats: Text files (.txt .csv .log .xml .json) plus .pdf .docx .xlsx .pptx and .dcm (DICOM). Their content is extracted and searched.
• Three search modes:
Normal: Plain substring match
Regex: Regular expression
Pattern File: Choose a named regular expression from the bundled patterns.txt. 32 ready-to-use patterns are included covering email, phone numbers, ID numbers, URLs, hash digests, API keys, and more.
• Hash computation: Optionally output MD5 / SHA-256 for each hit file in the result list.
• CSV export: Save the entire result list to a CSV file.
• See through disguised file extensions: Confidential documents disguised as backup files etc. (which would normally be skipped) are picked up and searched.
<How to Use>

5. Toggle options as needed (recursive search, case sensitivity, target file types, hash computation, etc.).
6. Click Search.
7. Double-click a row in the result list to open the file's location in Explorer (DICOM files open in the built-in viewer).
