function get_sfv_name trys to find name of .sfv file in releasename.
and from error (The system cannot find the path specified) it seems that script doesnt even checks if .sfv file is there, because path not found.
maybe u have some 'strange' chars in releasename.
apart of this error 3 problem that seemed to be a deleted dir,
what i said before is that with one release iojZS.exe is crashing at all. I tryed to have a look on the error and it seems to be inside unzip.cpp code (i compiled iojZS in asm format with BCC32 [-S flag] than with Olly Debugger recovered the error address and assembly code at that address then i had a look inside the .asm created by BCC32 for the same code as shown on olly debugger and find out that the error was generated inside a part of code of unzip.cpp).
these files cant be deleted include the speedtest, but wipe can do this.
iam using nxtools 1.0.6, if i uploaded any bad file to site, so its always dupe file, must be do "site undupe xxxx.xxx", it will be allow to upload again.
