In french: <Variable zipArchive>.EstMulti

Returns the type of archive: single-part archive or multi-part archive.

Example

MyArchive is zipArchive

ResOpenArchive = MyArchive.Open("D:\Backups\Backup.zip")

IF ResOpenArchive = 0 THEN
...
END
// Single-part or multi-part archive?

Syntax

<Result> = <Archive>.IsMulti()

<Result>: Boolean

True if the archive is a multi-part archive,
False if the archive is a single-part archive.

<Archive>: zipArchive variable

Name of a variable of type zipArchive corresponding to the archive to use.

Remarks

Use conditions

The archive type can be found only if the archive exists (archives are created using <zipArchive variable>.Create).
This function is available for WDZ, ZIP and 7z archives.

Reminder: Only ZIP, TAR and TGZ (TAR.GZ) archives are available.

Actions that can be performed on a multi-part archive

Some archiving functions can only be used on the single-part archives (add and delete files, create a self-extracting executable, etc.). To perform these operations, simply merge the sub-archives (<zipArchive variable>.Merge) to obtain a single-part archive.

From a multi-part archive, you can only:

Merge the different parts (<zipArchive variable>.Merge).
Get information about the archive and the files in the archive (<zipArchive variable>.ExtractPath, <zipArchive variable>.InfoFile, <zipArchive variable>.ListFile, etc.).
Extract the files (<zipArchive variable>.ExtractFile, <zipArchive variable>.ExtractAll).

Actions that can be performed on a single-part active

All archiving functions can be used on single-part archives, except <zipArchive variable>.Merge, which is used to merge the different parts of an archive.
