"Not a valid file name".

many of pdf files not open try windows, , try doing reader says "not valid file name".

it funny because able open them , hapens not able now.

it used hapen if had saved file long name, subseqently not able open nor copy windows, used rename (using windows of course) shorter name (the extension allways intact).

i have no problen opening other file or other pdf's, trying access particular files find myself problem (that did not have before; had been able open many of these files before).

i think , allmost problem reader , not widows, because program have updated reader.

all of articles use master's degree course in pdf worried stuck many of them...

thank you.

ps: before ask, files have no special characters (actually not allowed save file names these characters must know) , have *.pdf format.

try open them file open dialog box, not double-clicking ,
see happens.
