Hi Pablo;

On the following procedure you must only have care about files with some "danger" extension (as .EXE for instance)

cwpath              = "\\machine\c\myfolder\mysub"
cwoldtext           = "xxx"
cwnewtext           = "yyy"
Set defa to (cwpath)
nwtotalfiles        = 0
Dimension awFiles[1]
nwtotalfiles        = ADIR(awFiles,"*.*")
For ix = 1 TO nwtotalfiles
    cwbuff        = filetostr(awFiles[ix,1])
    do  while cwoldtext $ cwbuff
        if  at(cwoldtext, cwbuff) > 0
            cwbuff     = stuff(cwbuff, at(cwoldtext, cwbuff), len(cwoldtext), cwnewtext)
        endif
    Enddo
    =strtofile(cwbuff, awFiles[ix,1])
Endfor
