Extract text from Compressed archives (FOLDER)
To convert FOLDER archives to another format, you need 7-Zip or other Compressed software.
To convert other file formats to the "Archive Wrapper" file type, you need software like 7-Zip or a similar tool.
A .folder file is an uncommon, non-standard extension that typically functions as a generic container for other files. In the majority of cases (23%), this file is actually a standard ZIP compressed archive that has been renamed - intentionally or by error - to the .folder extension. Users frequently encounter this issue when downloading directory structures from web browsers or mobile operating systems that append the extension to represent a directory. Because neither Microsoft Windows nor macOS natively recognizes .folder as a valid archive type, the operating system treats it as an unknown generic file, preventing users from opening or inspecting the contents.
Less commonly (8%), a .folder file may be a proprietary ECG data storage container generated by medical devices from Mortara Instrument (now part of Hillrom). These files contain specialized Holter monitor or electrocardiogram readings used in clinical analysis. For the vast majority of users, the practical solution is to treat the file as a compressed archive: attempting to open it with a universal tool like 7-Zip or renaming the extension to ZIP will often restore access to the documents, images, or data inside.
Convert.Guru analyzes your FOLDER file, detects the exact format, and lets you read the text inside.

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 FOLDER converter.
