This script does what you need. You need to extend it to also manage the "Image Set 2" folder and its extension name, but It will be quite easy to just duplicate what's inside the Tell "Finder" block.
Because you have multiple folder, I used a sub-routine to process your folder, each time calling new rule. For instance the 1st rule is to process "Image Set 1, search for 0001,0002,0003,0004 and replace each with Front,Back,Top, Bottom.
The rule 2 is to process "Image Set 2, search for 0001,0002,0003,0004 and replace each with F,B,T, B.
The first part build the rules. The script itself is reduced to a loop through each rule, calling the sub-routine "Process_SubFolder" with the 3 variables: sub folder name, current targets and new names.
(*
Define record Rule, made of 3 variables :
NFolderNFolder: the name of sub-folder
NSource : the list of part of file names to be processed
NDest : the list of new names. This list MUST count same number of items as NSource
All rules are added into ListRules
*)
global ChosenName, ImagesFolder -- mandatory to use in the sub-routine
set Rule to {NFolder:"Image Set 1", NSource:{"0001", "0002", "0003", "0004"}, NDest:{"Front", "Back", "Top", "Bottom"}}
set ListRules to {Rule}
set Rule to {NFolder:"Image Set 2", NSource:{"0001", "0002", "0003", "0004"}, NDest:{"F", "B", "T", "B"}}
set ListRules to ListRules & {Rule}
set R to display dialog "Enter a name" default answer ""
set ChosenName to text returned of R
if ChosenName is "" then return -- no name selected, end of script
set ImagesFolder to choose folder with prompt "Choose Images Folder:"
repeat with aRule in ListRules
Process_SubFolder(NFolder of aRule, NSource of aRule, NDest of aRule)
end repeat
-- end of main script
on Process_SubFolder(LFolder, LSource, LDest)
tell application "Finder"
set SubFolder to (ImagesFolder as string) & LFolder
if folder SubFolder exists then
set FileList to every file of folder SubFolder -- get all files of Images Set 1
repeat with aFile in FileList -- loop through each file
set FName to name of aFile
set NewName to ""
-- Manage extension of the file
if name extension of aFile is "" then
set NewExt to ""
else
set NewExt to "." & name extension of aFile
end if
repeat with I from 1 to count of LSource --loop trhough each source of the rule
if FName contains (item I of LSource) then set NewName to ChosenName & (item I of LDest) & NewExt
end repeat
if NewName is not "" then set name of aFile to NewName -- only if name must be changed !
end repeat -- loop through files of LFolder
end if -- folder exists
end tell
end Process_SubFolder
With this structure, you can add as many rules as you want !
Of course, I assume that you will never get twice same names in sub folder ! It is not the case in Image Set 2, where you will have 2 files with new name = ChosenNameB : it will create an error !!
