Digby: A multi-file copmressor
|
|
|
|
There are some drawbacks to this application.
|
|
1) You can't compress multiple files or a folder at this moment.
|
|
2) It puts the files into memory, which is bad if the file you want to compress
|
|
is bigger than the memory you have.
|
|
3) There's no support for using the `*` modifier for compressing all files in
|
|
working directory.
