AbiWord is an open-source word processor from AbiSource. Its AbiCollab system supports collaborative work on documents, and an ABICOLLAB file stores descriptor information for a collaborative AbiWord document.
An ABICOLLAB file is separate from a regular AbiWord document and is mainly useful with an AbiWord version that supports the AbiCollab feature. The software linked to this record runs on Microsoft Windows.
Open an ABICOLLAB file with AbiWord on Microsoft Windows. You can open it from AbiWord's Open dialog or associate the file extension with AbiWord and double-click the file.
AbiWord may use the file to access the associated collaborative document rather than display ordinary document text directly.
An ABICOLLAB file is not normally converted directly because it describes access to a collaborative AbiWord document rather than serving as a standalone document format. Open it in AbiWord and, if the associated document is available, save or export that document to a format supported by AbiWord.
