# vfscopy # [vfscopy](https://git.rootprojects.org/root/vfscopy)
Copy a Virtual FileSystem, such as Recursively copy a Virtual FileSystem, such as
[http.FileSystem](https://golang.org/pkg/net/http/#FileSystem), [http.FileSystem](https://golang.org/pkg/net/http/#FileSystem),
recursively to a native file system destination. to a native file system destination.
Works with any file system that implements http.FileSystem, Works with any file system that implements http.FileSystem,
such as `vfsgen`, `fileb0x`, `gobindata`. including `vfsgen`, `fileb0x`, `gobindata` and most others.
## Example: native file system (os)
```go ```go
httpfs := http.Dir("/tmp/public/") httpfs := http.Dir("/tmp/public/")
vfs := vfscopy.NewVFS(httpfs) vfs := vfscopy.NewVFS(httpfs)
if err := Copy(vfs, ".", "/tmp/dst/"); nil != err { if err := vfscopy.CopyAll(vfs, ".", "/tmp/dst/"); nil != err {
fmt.Fprintf(os.Stderr, "couldn't copy vfs: %v\n", err) fmt.Fprintf(os.Stderr, "couldn't copy vfs: %v\n", err)
} }
``` ```
## Example: vfsgen
**Note**: `vfsgen` does not support symlinks or file permissions.
```go
package main
import (
"fmt"
"git.rootprojects.org/root/vfscopy"
// vfsgen-generated file system
"git.example.com/org/project/assets"
)
func main() {
vfs := vfscopy.NewVFS(assets.Assets)
if err := vfscopy.CopyAll(vfs, ".", "/tmp/dst/"); nil != err {
fmt.Fprintf(os.Stderr, "couldn't copy vfs: %v\n", err)
}
fmt.Println("Done.")
}
```
