Unknown file extension
File type: Unknown file
The .otherfolder file extension is not associated with a documented file format or known software product.
The file's purpose and contents cannot be determined from this extension alone.
File type category:
Unknown file

No vendor, software application, platform, purpose, or internal structure has been identified for the .otherfolder file extension.
Because this is an unknown file extension, the file may belong to a private or unidentified application, but its format cannot be reliably described or confirmed.
There is no known program that can reliably open an .otherfolder file. The application that created the file is needed to determine how it should be opened.
A plain-text editor can be used to check whether the file contains readable text, but it will not correctly open an unknown binary file.
An .otherfolder file cannot be sensibly converted without first identifying its format and the software that created it.
Once the originating application is known, use that application's own export or save-as function, if available.
