ArcConvert is a free, portable, open source program for Windows that lets you convert file archives from one format to another. This is different from typical file converter software that you come across because almost none of them supports archive file formats.
Though most file archive programs can open a handful of different file archives, there are a still a large number of obscure file formats that won’t open with the file archiver you have installed in your machine. Say for example, neither 7-zip nor WinRAR supports YZ1, GCA, BEL, PMA, ALZ and a lot of other file extensions. (On a side note, have you ever looked beyond WinRAR, WinZip and 7-zip? No? There are lot’s of alternatives. Bitser is another good one). It’s highly unlikely that you will come across an archived file in any one of those formats, but can never say for sure.
ArcConvert can convert the following file formats:
7-ZIP/ LZH / CAB / ZIP / ARJ / ACE / RAR / TAR / TGZ / GZ / Z / BZ2 / YZ1 / YZ2 / GCA / BEL / RPM / DEB/ BH / Noa32 / HKI / PAQAR / QX /HA /ZOO /UHARC /LFB / ZLIB / UCL / IMP / RS / SPL / APK / Arc / DZ / MSI / ALZ / PMA / PAQ7 / CHM / UDA / PAQ8 / Cryptonite / ISO / LZOP / BMA / ZIP AES (128/192/256) / Nanozip Alpha/ XZ/ FreeArc/Zpaq/GZA
to the following ones:
ZIP, 7-ZIP, CAB, LHA, TAR, TGZ, BZ2, YZ1, BGA, RAR, ACE, NOA32, PAQAR, UHARC, YZ2, DZ, HA, XZ, FreeArc, ARJ/PAQ9/GZA
I have to admit, most of these names look alien to me.
If the archive is password protected, ArcConvert detects it automatically and prompts you to enter the password during conversion.
This application is going to come handy someday. If you are looking for an online solution, Zamzar does support quite a few.
