How does unzip:to: access to the file ?

I do not get your question?

It must be in the workingDirectory?

Read the code luke....

unzip: fullFileName to: pathString
�� "Unzip the contents of the file specified by the full path name fullFileName to the location given by pathString."

�� | zipped buffer unzipped newName |
�� newName := fullFileName copyUpToLast: FileSystem disk extensionDelimiter.
�� pathString asFileReference ensureCreateDirectory.
�� unzipped := FileStream newFileNamed: (pathString asFileReference / newName) fullName.
�� ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

�� unzipped ifNil: [self error: pathString, ' looks incorrect'].
�� [ unzipped binary.
�� zipped := self on: (FileStream readOnlyFileNamed: fullFileName).
�� buffer := ByteArray new: 50000.
�� [zipped atEnd] whileFalse: [unzipped nextPutAll: (zipped nextInto: buffer)]]
�� ensure: [
�� zipped close.
�� unzipped close].
�� ^ newName

I use it a lot to uncompress external resources like this:

fileRef := ....
GZipReadStream unzip: fileRef basename to: FileSystem workingDirectory.

but it could be used to pass a directory as String I guess.

Comment should be corrected.

unzip: fullFileName to: pathString
�� "Unzip the contents of the file specified by the full path name fullFileName to the location given by pathString."

so we would expect to pass a string in the second argument?

the unique sender of it in the system

unzip: fullFileName
�� "Unzip the contents of a gzipped file specified by its full file name to the current working directory"

�� ^ self unzip: fullFileName to: FileSystem disk workingDirectory

but the implementation seems to indicate that fullFileName is should be a string as well as pathString

unzip: fullFileName to: pathString
�� "Unzip the contents of the file specified by the full path name fullFileName to the location given by pathString."

�� | zipped buffer unzipped newName |
�� newName := fullFileName copyUpToLast: FileSystem disk extensionDelimiter.
�� pathString asFileReference ensureCreateDirectory.
�� unzipped := FileStream newFileNamed: (pathString asFileReference / newName) fullName.
�� unzipped ifNil: [self error: pathString, ' looks incorrect'].
�� [ unzipped binary.
�� zipped := self on: (FileStream readOnlyFileNamed: fullFileName).
�� buffer := ByteArray new: 50000.
�� [zipped atEnd] whileFalse: [unzipped nextPutAll: (zipped nextInto: buffer)]]
�� ensure: [
�� zipped close.
�� unzipped close].
�� ^ newName

Am I correct to think that the comments are not really good enough?
