Test if all file types exist in the path you know.
(For windows below codes are working)

Note: The current test code is an alternative to "LuaFileSystem" (lfs.).

Code:
function pathExist(pth,fl1)
local file=pth..fl1
  local fl2  = os.rename(file, file)
  if not fl2 then
  print("File not found")
  else
  print("file available")
 end
 return fl2
end


Use:
Code:
--Folder
pathExist([[C:\Users\YourUserName\OneDrive\]],"Pictures")


Code:
--files
pathExist([[C:\Users\YourUserName\Desktop\]],"Sample.txt")


-------------------------------- or check and reName:
Code:
function pathExist(pth,fl1,refl)
local file=pth.."\\"..fl1
  local fl2  = os.rename(file, file)
  if not fl2 then
  print("File not found")
  else
  if refl=="" then
  print("file available")
  else
  local file1=pth.."\\"..refl
  local fl2  = os.rename(file, file1)
  print("New File name: "..refl.." success!")
  end
 end
 return fl2
end


--Use check name:
Code:
local cedir=getCheatEngineDir()
--or [[C:\Program Files\Cheat Engine 7.2]]

pathExist(cedir,"lua53-32.dll","")


--Use rename:
Code:
pathExist([[C:\Users\YourUserName\Desktop]],"lost1.txt","lost2.txt")


Enjoy it!

    return vrs2
    else
    print("File: '"..vrs1.."' Newer!")
    return vrs1
   end
  end
end

 local pth=[[C:\Users\YourUserName\Desktop]] --edit YourUserName
rst1=pathExist(pth .. "\\CT_V14.122.txt",pth .. "\\CT_V14.132.txt")
print(rst1)


-->rst1
--File: 'CT_V14.132.txt' Newer!
