Extract text from search index files (CRWL)
To convert CRWL index files to another format, you need Windows Search Indexer or other System software.
To convert other file formats to the "Windows Crawl File" file type, you need software like Windows Search Indexer or a similar tool.
A .CRWL file is a temporary system file generated by the Microsoft Windows Search Indexer. It acts as a crawl file, logging the status of directories and files currently being scanned to build the main Windows Search database. Under the hood, these files often store data in raw UTF-16 (LE) text encoding.
Because they are proprietary system caches, .CRWL files pose significant usability challenges. They are not meant to be opened by users. Frequently, these files become bloated and consume gigabytes of storage space in the C:ProgramData\Microsoft\Search\Data directory. Furthermore, they do not contain your actual documents, photos, or videos - only the metadata and index paths used by the operating system. Attempting to open a .CRWL file in standard text editors like Notepad will usually result in locked file errors or sluggish performance due to massive file sizes.
Directly converting a .CRWL file to standard document formats like PDF or DOCX is impossible because it is a raw system log, not a user document. However, system administrators and forensic analysts often extract the internal strings into TXT or CSV formats to audit what the system was indexing.
Standard online converters fail to process this closed, proprietary format. Drag and drop your file to see what it is and convert it if supported. convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your CRWL file, detects the exact format, and lets you read the text inside.
Users also converted GTHR, DEL and EX files.
If you want to convert CRWL file to TXT, RTF, DOC, DOCX, ODT, PAGES, TEX, LATEX, MD, MARKDOWN, LOG or NFO, you can use Windows Search Indexer or similar software from the "Search Index Temporary Log" category. In the File menu, look for Save As… or Export….
To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to CRWL, try Windows Search Indexer or another comparable tool in the "Search Index Temporary Log" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CRWL converter.
