+import { split, slice } from "std/text"
+
+const reduceFactor = 10
+
+// this main function allows using arguments
+main(args){
+
+    echo(args[1])
+
+    // accepting first argument  as folder. index 0 is just main.ab or bash
+    const folder = args[1]
+
+
+    // using commands and getting its output into text variable named 'res'
+    let filesSortedByTimeStr = $ ls -t "{folder}" $ failed {echo(-1)}
+
+    // converting string to array with demiliter
+    let filesSortedByTimeArray = split(filesSortedByTimeStr, "\n")
+
+    let abFilesSortedByTimeArray = []
+    for index,file in filesSortedByTimeArray{
+
+        if slice(file, -4) == ".fos" {
+        // add elements into array
+            abFilesSortedByTimeArray+=[file]
+
+        }
+    }
+
+    const bufferFolder = "{folder}/tobedeleted"
+    $ mkdir -p "{bufferFolder}" $ failed {echo("couldnt created tobedeleted folder")}
+    for index,file in abFilesSortedByTimeArray{
+        if index % reduceFactor != 0{
+            $ mv "{folder}/{file}" "{bufferFolder}/" $ failed {}
+        }
+    }
