ConvertArchive (Convert archives to a different format)

Buttons/Scripts
, ,
1

ConvertArchive copies the content of selected archives into new archive containers in a different format (7z, RAR, ZIP). The original archives are not deleted. Archives that already have a target archive will be skipped. The add-in uses the internal Copy command for all conversions.

Arguments

  • FORMAT Determines the container format. Uses the same syntax as the ARCHIVE argument. If omitted, .zip is used.

  • TO Determines the target directory. If omitted, the source directory is used.

  • COPYTIMESTAMPS Copies the created and modified timestamps to the new archive container.

  • DRYRUN Creates and logs the internal commands without executing them.

  • NOLOG Disables logging. This is overridden by DRYRUN.

Examples

ConvertArchive FORMAT=.7z                   // create 7z

ConvertArchive FORMAT=.zip,split:100kb      // create zip, split into .z* files

ConvertArchive TO={destpath}

ConvertArchive COPYTIMESTAMPS

How to set up and use

:one: Save CommandConvertArchive.js.txt to   ↓

:two: Add the new command to a button, hotkey, context menu, etc., just like a built-in command, or run it from the FAYT Command field.

How to Convert a .zip to a .7z in a Single Button

Nice!

What if one would like the option to delete the original archive once the conversion was completed/confirmed?

3

The archives that actually get converted will be selected once the script is finished - just hit delete. I am always a bit nervous when auto-deleting files but I'd wouldn't mind adding a delete option. Are you brave enough?

There's a fine line between brave and foolish. I walk it all too often... :wink:

Alright, here's a new version that adds DELETEORIGINAL. You can also pass QUIET to suppress the confirmation dialog and NORECYCLE to skip the recycle bin.

I'll update the main post in a few days if nobody gets hurt :wink:

Enjoy the walk!

:joy: agreed. Auto-delete is great but scary. Got to double-check the duplicates! Before it's sent to the bin.

Balancing bravery with common sense, I tied the new version to a button as follows:

@keydown:none
ConvertArchive Format=.zip
@keydown:ctrl
ConvertArchive DELETEORIGINAL Format=.zip
@keydown:shift
ConvertArchive DELETEORIGINAL NORECYCLE Format=.zip

Works well!

Thanks, as always, @lxp !
