* Create new file in a collection:
```{r}
-collection$create(fileNames, optionalRelativePath)
+collection$create(files)
```
Example:
```{r}
-mainFile <- collection$create("main.cpp", "cpp/src/")
-fileList <- collection$create(c("main.cpp", lib.dll), "cpp/src/")
+mainFile <- collection$create("cpp/src/main.cpp")
+fileList <- collection$create(c("cpp/src/main.cpp", "cpp/src/util.h"))
```
-* Add existing ArvadosFile or Subcollection to a collection:
-
-```{r}
-folder <- Subcollection$new("src")
-file <- ArvadosFile$new("main.cpp")
-folder$add(file)
-```
-
-```{r}
-collection$add(folder, "cpp")
-```
-
-This examples will add file "main.cpp" in "./cpp/src/" folder if folder exists.
-If subcollection contains more files or folders they will be added recursively.
-
* Delete file from a collection:
```{r}
Make sure to include new file name in destination.
In second example file$move("newDestination/") will not work.
+* Copy file or folder inside collection:
+
+Directley from collection
+
+```{r}
+collection$copy("folder/file.cpp", "file.cpp")
+```
+
+Or from file
+
+```{r}
+file <- collection$get("location/to/my/file.cpp")
+file$copy("destination/file.cpp")
+```
+
+Or from subcollection
+
+```{r}
+subcollection <- collection$get("location/to/folder")
+subcollection$copy("destination/folder")
+```
